ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

ABSTRACT In March 2016, wilt and shoot blight were observed on five-year-old apple trees (Malus domestica) cultivar Maxi Gala in a commercial orchard in São Joaquim city, state of Santa Catarina, Brazil. Isolation on culture media, biolog, biochemical, LOPAT tests, and whole genome sequencing were performed. Koch’s postulates were fulfilled on apple stems, leaves and fruits. The taxonomic position of a representative strain was determined by in silicoDNA-DNA hybridization using the Genome-to-Genome Distance Calculator which showed 93.9% similarity with Pseudomonas syringae. Results of biolog and biochemical tests did not match those expected for pv. papulans, morsprunorum or syringae. To our knowledge this is the first report of P. syringae causing bacterial canker in commercial apple orchards in Brazil.

ABSTRACT Cactaceae species are karyotypically well-known with x = 11 and chromosome number variation due mainly to polyploidization. However, both assumptions are based on descriptive observations without taking an evolutionary framework of Cactaceae into account. Aiming to confirm these hypotheses in an evolutionary context, we obtained chromosome numbers for 20 species of Cactoideae, performed an extensive review of chromosome number for the family, and analyzed these data using a phylogenetic approach. The karyotypes presented here were characterized by CMA/DAPI banding, and for six species 5S and 45S rDNA sites were located. Our data, along with a survey of the literature, reinforce the long-standing hypothesis of a x = 11 as the base chromosome number for Cactaceae. They also reinforce the relevance of polyploidy in karyotype evolution of cacti, although polyploidy was important just after the diversification of subfamilies Maihuenioideae and Pereskioideae. Despite the homogeneous chromosome complements observed among cacti, chromosome banding and FISH techniques revealed informative characteristics, allowing the identification of chromosome synapomorphies, such as proximal CMA+ bands in Melocactus and proximal 5S rDNA in Pilosocereus, indicating the taxonomic potential of chromosome characterization in cacti.

Abstract This study aimed to evaluate the performance in feedlot and temperament of Nellore bulls classified by residual feed intake. The residual feed intake was calculated as the difference between the observed and predicted dry matter intake. Bulls classified as low residual feed intake had lower dry matter intake (kg day−1) and dry matter intake (g kg−1 d−1) of body weight, and were more efficient in feed conversion ratio than those classified as medium and high. The average daily gain didn’t differ among residual feed intake classes and was 1.69 kg day−1, 1.82 kg day−1 and 1.71 kg day−1 for bulls classified as low, medium, or high, respectively. The residual feed intake was positively associated with dry matter intake, feed conversion ratio and subcutaneous fat thickness. The subcutaneous fat thickness was lower in bulls classified as low residual feed intake than in those with medium and high. No differences were observed in flight speed and reactivity score among residual feed intake classes. Overall, we concluded that bulls classified as low residual feed intake consumed less dry matter than high, with no differences in average daily gain, temperamentand had better feed efficiency, albeit their subcutaneous fat thickness was lower.

Abstract The asymmetry indexes have helped cytotaxonomists to interpret and classify plant karyotypes for species delimitation efforts. However, there is no consensus about the best method to calculate the intrachromosomal asymmetry. The present study aimed to compare different intrachromosomal asymmetry indexes in order to indicate which are more efficient for the estimation of asymmetry in different groups of orchids. Besides, we aimed to compare our results with the Orchidaceae phylogenetic proposal to test the hypothesis of Stebbins (1971). Through a literature review, karyotypes were selected and analyzed comparatively with ideal karyotypes in a cluster analysis. All karyotypes showed some level of interchromosomal asymmetry, ranging from slightly asymmetric to moderately asymmetric. The five tested intrachromosomal asymmetry indexes indicated Sarcoglottis grandiflora as the species with the most symmetrical karyotype and Christensonella pachyphylla with the most asymmetrical karyotype. In the cluster analysis, the largest number of species were grouped with the intermediary ideal karyotypes B or C. Considering our results, we recommend the combined use of at least two indexes, especially Ask% or A1 with Syi, for cytotaxonomic analysis in groups of orchids. In an evolutionary perspective, our results support Stebbins’ hypothesis that asymmetric karyotypes derive from a symmetric karyotypes.

Objetivou-se com esta pesquisa avaliar a competição interespecífica do Panicum maximum cv. Aries no período de estabelecimento, sendo os fatores estudados os níveis de sombreamento e de nitrogênio. Os níveis de sombreamento provocados pelas plantas daninhas foram de 0%, até 40%, até 70% e 60%, na ausência e na presença de nitrogênio. Foram analisados: altura de planta, dinâmica de perfilhamento, índice de área foliar (IAF), matéria seca, material senescente de folha e intensidade de competição relativa (ICR) de P. maximum cv. Aries com as plantas daninhas. Os dados foram submetidos a testes de homogeneidade de variâncias e normalidade de resíduos, e então realizados análises de variância (ANOVA), teste de média (Tukey) ao nível de 5% de probabilidade e regressão. As características morfológicas e produtividade do P. maximum cv. Aries apresentaram melhores respostas em condição de não interferência das plantas daninhas. O nitrogênio contribuiu para um melhor desenvolvimento de P. maximum cv. Aries, contudo no tratamento de convívio com as plantas daninhas sem corte houve o domínio sobre o P. maximum cv. Aries. O corte realizado nas plantas daninhas promoveu a diminuição da intensidade de competição interespecífica. A condição variável de sombreamento no tempo exprime diferentes respostas morfológicas em comparação com uma condição homogênea, interferindo principalmente na velocidade de estabelecimento do P. maximum cv. Aries.
ABSTRACT The aim of this research was to evaluate interspecific competition in Panicum maximum cv. Aries during the establishment period, studying the factors of shading and nitrogen levels. The levels of shading caused by the weeds ranged from 0% and 40% to 70% and 60% with no nitrogen and in the presence of nitrogen. Analyses were made of plant height, tiller dynamics, leaf area index (IAF), dry matter, senescent leaf material and relative competition intensity (ICR) in P. maximum cv. Aries when with weeds. The data were submitted to tests for homogeneity of variance and residual normality; analysis of variance (ANOVA), Tukey's mean difference test at 5% probability, and regression analysis were then carried out. The morphological and yield characteristics of P. maximum cv. Aries responded better where there was no interference from the weeds. Nitrogen contributed to greater development in P. maximum cv. Aries, but when coexisting with the uncut weeds, the weeds dominated the P. maximum cv. Aries. Cutting the weeds caused a reduction in the intensity of interspecific competition. The variable conditions of shade over time express different morphological responses in comparison to a homogeneous situation, mainly interfering in the speed of establishment of P. maximum cv. Aries.

RESUMO Os impactos das práticas de manejo intensivo sobre a sustentabilidade da produção florestal dependem da manutenção da fertilidade do solo. A contribuição dos resíduos florestais e da ciclagem de nutrientes nesse processo é crucial. Avaliou-se uma plantação de 16 anos de idade de Pinus taeda em um Cambissolo Húmico Alumínico léptico de textura argilosa, relevo ondulado, no meio-sul catarinense. Dez árvores foram amostradas em cinco classes de diâmetro, de acordo com a distribuição de diâmetro à altura do peito. A biomassa de acículas, galhos, casca, madeira e raízes foi medida para cada árvore. Além da biomassa vegetal, amostraram-se serapilheira acumulada e solo nas camadas de 0,00-0,20; 0,20-0,40; 0,40-0,60; 0,60-1,00; 1,00-1,40; 1,40-1,80, e 1,80-1,90 m. A concentração de nutrientes, o balanço de nutrientes e a caracterização mineralógica foram determinados a partir das amostras de solo coletadas. Três cenários de intensidade de colheita foram simulados, considerando a remoção de madeira (A), madeira e casca (B) e madeira, casca e copa (C). A soma de todos os componentes da biomassa foi de 313 Mg ha-1. O estoque de nutrientes na árvore foi N>Ca>K>S>Mg>P. A mineralogia do Cambissolo Húmico Alumínico léptico evidenciou a predominância de areia de quartzo e pequenos traços de vermiculita na fração silte. A argila é a principal fração que contribui para o intemperismo do solo em razão da transformação de ilita-vermiculita liberando K. O esgotamento dos nutrientes do solo a partir da biomassa foi: P>S>N>K>Mg>Ca. Fósforo e S permaneceram como os nutrientes mais limitantes no cenário A, por causa dos seus baixos estoques disponíveis no solo. No cenário B, o número de rotações florestais foi limitado para N, K e S. O cenário C resultou na maior diminuição de produtividade, e limitado pelo P, apresentando apenas duas potenciais rotações de cultivo para esse nutriente. Dessa forma, evidenciou-se, pelo número potencial de rotações de cultivo, que entre o cenário A, menos exaustivo, e cenário C, mais exaustivo, uma diferença de até 30 anos na capacidade de suporte do solo. Assim, o efeito de diferentes intensidades de colheita sobre a disponibilidade de nutrientes pode comprometer a sustentabilidade do P. taeda em longo prazo.
ABSTRACT The impact of intensive management practices on the sustainability of forest production depends on maintenance of soil fertility. The contribution of forest residues and nutrient cycling in this process is critical. A 16-year-old stand of Pinus taeda in a Cambissolo Húmico Alumínico léptico (Humic Endo-lithic Dystrudept) in the south of Brazil was studied. A total of 10 trees were sampled distributed in five diameter classes according to diameter at breast height. The biomass of the needles, twigs, bark, wood, and roots was measured for each tree. In addition to plant biomass, accumulated plant litter was sampled, and soil samples were taken at three increments based on sampling depth: 0.00-0.20, 0.20-0.40, 0.40-0.60, 0.60-1.00, 1.00-1.40, 1.40-1.80, and 1.80-1.90 m. The quantity and concentration of nutrients, as well as mineralogical characteristics, were determined for each soil sample. Three scenarios of harvesting intensities were simulated: wood removal (A), wood and bark removal (B), and wood + bark + canopy removal (C). The sum of all biomass components was 313 Mg ha-1.The stocks of nutrients in the trees decreased in the order N>Ca>K>S>Mg>P. The mineralogy of the Cambissolo Húmico Alumínico léptico showed the predominance of quartz sand and small traces of vermiculite in the silt fraction. Clay is the main fraction that contributes to soil weathering, due to the transformation of illite-vermiculite, releasing K. The depletion of nutrients from the soil biomass was in the order: P>S>N>K>Mg>Ca. Phosphorus and S were the most limiting in scenario A due to their low stock in the soil. In scenario B, the number of forest rotations was limited by N, K, and S. Scenario C showed the greatest reduction in productivity, allowing only two rotations before P limitation. It is therefore apparent that there may be a difference of up to 30 years in the capacity of the soil to support a scenario such as A, with a low nutrient removal, compared to scenario C, with a high nutrient removal. Hence, the effect of different harvesting intensities on nutrient availability may jeopardize the sustainability of P. taeda in the short-term.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

Objetivos:Avaliar a relação entre o polimorfismo 3111 T/C do gene CLOCK (rs1801260) e a presença de obesidade, bem como a duração do sono, em crianças de 6 a 13 anos. Em adultos, essa variante genética foi associada à duração do sono, níveis de grelina, peso e padrão alimentar. Embora, em crianças, a curta duração do sono tenha sido relacionada à obesidade, até o momento nenhum estudo foi direcionado no sentido de identificar possíveis mecanismos moleculares dessa associação.Métodos:Peso, altura e circunferências foram transformados em escores-Z para idade e sexo. A genotipagem foi realizada pela metodologia Taqman. Um questionário sobre horas de sono foi entregue aos pais. Testes estatísticos apropriados foram realizados.Resultados:Foram avaliadas 370 crianças (45% meninos, 55% meninas, idade média 8,5±1,5 anos). A prevalência de excesso de peso foi de 18%. A duração do sono foi, em média, 9,7 horas, sendo inversamente relacionada à idade (p < 0,001). A distribuição genotípica foi: 4% CC, 31% TC e 65% TT. Houve uma tendência de maior prevalência de excesso de peso em crianças que dormiam menos de 9 h (23%), quando comparadas às que dormiam mais de 10 h (16%, p = 0,06). O genótipo não se correlacionou significativamente a nenhum dos desfechos avaliados.Conclusões:O polimorfismo CLOCK 3111 T/C não está significativamente associado ao excesso de peso ou à duração do sono em crianças desta localidade.
Objectives:To evaluate the association between 3111T/C polymorphism of the CLOCK gene and the presence of obesity and sleep duration in children aged 6-13 years. In adults, this genetic variant has been associated with duration of sleep, ghrelin levels, weight, and eating habits. Although short sleep duration has been linked to obesity in children, no study has aimed to identify the possible molecular mechanisms of this association to date.Methods:Weight, height, and circumferences were transformed into Z-scores for age and gender. Genotyping was performed using TaqMan methodology. A questionnaire regarding hours of sleep was provided to parents. The appropriate statistical tests were performed.Results:This study evaluated 370 children (45% males, 55% females, mean age 8.5 ± 1.5 years). The prevalence of overweight was 18%. The duration of sleep was, on average, 9.7 hours, and was inversely related to age (p < 0.001). Genotype distribution was: 4% CC, 31% CT, and 65% TT. There was a trend toward higher prevalence of overweight in children who slept less than nine hours (23%) when compared to those who slept more than ten hours (16%, p = 0.06). Genotype was not significantly correlated to any of the assessed outcomes.Conclusions:The CLOCK 3111T/C polymorphism was not significantly associated with overweight or sleep duration in children in this city.

Neste experimento foram comparados os métodos de coleta total de fezes (CT) e de indicadores internos (cinza insolúvel em ácido - CIA, fibra bruta - FB e fibra em detergente ácido - FDA) na determinação dos coeficientes de digestibilidade aparente (CDA) da matéria seca (MS), proteína bruta (PB), extrato etéreo (EE), extrativo não nitrogenado (ENN) e energia bruta (EB) de uma ração comercial de gatos-domésticos para jaguatiricas (Leopardus pardalis). Seis animais adultos com peso de 12,45 ± 1,37kg receberam gradativamente a ração experimental na dieta habitual até o início do experimento e foram submetidos a um período de adaptação de 10 dias anteriores ao período de coleta. Os CDA obtidos pela CT, CIA, FB e FDA foram, respectivamente de 73,70; 76,83; 62,01 e 46,03% para matéria seca, 81,9; 84,8; 75,8 e 63,8% para proteína bruta, 85,0; 86,7; 78,5 e 69,1% para extrato etéreo, 78,52; 79,55; 69,11 e 53,04% para extrativo não nitrogenado e de 80,5; 82,2; 71,4 e 58,4% para energia bruta. O método de CIA mostrou-se eficiente na determinação dos coeficientes de digestibilidade aparente e pode contribuir com as investigações sobre a digestibilidade em dietas com felídeos selvagens. A ração utilizada permitiu aos animais um adequado aporte nutricional e apresentou menores custos/animal/dia em comparação aos itens que compunham a dieta habitual.
In this experiment, methods of total fecal collection (TFC) and internal markers (acid-insoluble ash - AIA, crude fiber - CF, and acid-detergent fiber - ADF) were compared for determination of the coefficients of apparent digestibility (CAD) for dry matter (DM), crude protein (CP), ether extract (EE), nitrogen-free extracts (NFE), and gross energy (GE) of commercial feline dry kibble for ocelots (Leopardus pardalis). Six adult animals, weighing 12.45±1.37 kg, gradually received experimental kibble in their usual diet until the beginning of the experiment and were submitted to an adaptation period ten days prior to the collection period. CAD obtained by TFC, AIA, CF, and ADF were, respectively, 73.7, 76.83, 62.01, and 46.03% for dry matter; 81.9, 84.8, 75.8, and 63.8% for crude protein; 85, 86.7, 78.5, and 69.1% for ether extract; 78.52, 79.55, 69.11, and 53.04% for nitrogen-free extracts; and 80.5, 82.2, 71.4, and 58.4% for gross energy. The AIA method showed to be efficient in determining coefficients of apparent digestibility and may contribute to investigations on the digestibility of diets for wild felines. In comparison to the items of ocelot's usual diet, the kibble used in this paper provided an adequate nutritional supply with reduced daily costs per animal.

O objetivo deste trabalho é descrever, em três propriedades rurais no Estado de Mato Grosso, a epidemiologia, o quadro clínico e o patológico da obstrução intestinal por fitobezoares em bovinos que pastoreavam em piquetes com predomínio de Stylosanthes sp. pelo menos 60 dias. A morbidade variou de 3,3% a 15% e a mortalidade foi de 100%. O quadro clínico foi de cólica abdominal caracterizado por apatia, anorexia, inquietação, desconforto, sudorese e vocalização, seguido por episódios de diarreia ou diminuição da produção fecal, desidratação, hipomotilidade gastrintestinal, aumento do volume abdominal, decúbito esternal ou lateral com a cabeça voltada para o flanco e morte. O curso clínico foi de 2-7 dias. A principal alteração notada durante a necropsia dos bovinos foi a obstrução intestinal por fitobezoar ovoide de 2-5 cm de diâmetro, frequentemente no duodeno, próximo ao piloro, ocasionalmente em sua porção média. Na área de obstrução notou-se a necrose da parede intestinal que estava enegrecida e intensamente demarcada em relação a segmento adjacente normal, além de intenso espessamento associado a edema, congestão e hemorragia. O abomaso e os segmentos intestinais anteriores a obstrução apresentavam-se repletos de conteúdo alimentar líquido e posteriormente estava com ausência de conteúdo. O rúmen frequentemente tinha grande quantidade de conteúdo liquido a pastoso. Em todos os bovinos necropsiados múltiplas estruturas sólidas, arredondadas ou ovoides, esverdeadas (fitobezoares) foram observadas no abomaso. Estes achados indicam que pastagens com predomínio de Stylosanthes sp. predispõem a formação de fitobezoares, os quais podem levar à obstrução intestinal e morte em bovinos.
The clinical and pathological findings of intestinal obstruction caused by phytobezoars in cattle consuming Stylosanthes sp. on three farms in Mato Grosso, Brazil, are described. The morbidity varied from 3.3 to 15% and the mortality was 100%. The animals stayed on pastures with predominance of Stylosanthes sp. for at least 60 days. The overall clinical picture was apathy followed by episodes of diarrhea or reduced feces and separation from the herd. Individual clinical signs were abdominal colic characterized by anorexia, discomfort, gastrointestinal hypomotility, dehydration, increased abdominal size, sweating, vocalization, sternal or lateral recumbence with the head on the flank. The clinical course lasted from 2 to 7 days. At necropsy, duodenal or pyloric obstruction was caused by ovoid phytobezoars of 2-4cm diameter; in the area of obstruction friable intestinal tissue with intense swelling, congestion, edema, and reddish mucosa was found. The rumen, abomasum and duodenum proximal to the site of obstruction was filled with greenish liquid, and absence of food contents was observed distally to the phytobezoars. Histologically, at the site of obstruction, the duodenum exhibited diffuse necrosis of the mucosal surface, thickening of the wall by submucosal edema, neutrophilic infiltration, fibrin deposition, necrosis of smooth muscle fibers, and marked congestion or hemorrhage. Pasture with the predominance of Stylosanthes sp. is a serious problem due to the possibility of phytobezoar formation, thus leading to intestinal obstruction and high mortality rates in cattle.

The common bean is one of the most important legumes in the human diet, but little is known about the endophytic bacteria associated with the leaves of this plant. The objective of this study was to characterize the culturable endophytic bacteria of common bean (Phaseolus vulgaris. leaves from three different cultivars (Vermelhinho, Talismã, and Ouro Negro) grown under the same field conditions. The density of endophytic populations varied from 4.5 x 10² to 2.8 x 10³ CFU g-1 of fresh weight. Of the 158 total isolates, 36.7% belonged to the Proteobacteria, 32.9% to Firmicutes, 29.7% to Actinobacteria, and 0.6% to Bacteroidetes. The three P. vulgaris cultivars showed class distribution differences among Actinobacteria, Alphaproteobacteria and Bacilli. Based on 16S rDNA sequences, 23 different genera were isolated comprising bacteria commonly associated with soil and plants. The genera Bacillus, Delftia, Methylobacterium, Microbacterium, Paenibacillus, Staphylococcus and Stenotrophomonas were isolated from all three cultivars. To access and compare the community structure, diversity indices were calculated. The isolates from the Talismã cultivar were less diverse than the isolates derived from the other two cultivars. The results of this work indicate that the cultivar of the plant may contribute to the structure of the endophytic community associated with the common bean. This is the first report of endophytic bacteria from the leaves of P. vulgaris cultivars. Future studies will determine the potential application of these isolates in biological control, growth promotion and enzyme production for biotechnology.

Este estudo disponibiliza dados sobre a fauna de Scarabaeinae que ocorre em plantio de eucalipto inserido em uma área originalmente aberta, citando quais espécies conseguem se estabelecer neste ambiente introduzido e sombreado. O levantamento de Scarabaeinae foi realizado em uma área de monocultura de eucalipto com armadilhas de interceptação de voo e armadilhas de queda iscadas com fezes humanas, banana em decomposição e carcaça, entre os meses de dezembro de 2005 e novembro de 2006. Foram capturadas 28 espécies pertencentes a 11 gêneros. Destas, 11 já foram registradas em ambientes de campo e mata nativa da região, outras 11 apenas em campo nativo, duas mostraram-se exclusivas ao plantio de eucalipto e quatro não foram identificadas a nível específico, o que não possibilitou a obtenção de maiores informações sobre registros em ecossistemas naturais da região. Os resultados obtidos mostraram que as espécies que ocorrem em eucalipto são generalistas em relação ao hábitat, apresentam preferência por ambientes sombreados e/ou são espécies "turistas". Este, contudo, representa um dos poucos levantamentos realizados na região e por isso, novos estudos são necessários a fim de obter maiores informações acerca da distribuição e resposta dos escarabeíneos aos sistemas naturais e antropizados.
This study provides data about the Scarabaeinae fauna that occurs in a eucalyptus plantation inserted in an originally open area, describing which are able to establish themselves in this introduced and shaded environment. The survey was carried in an area of eucalyptus monoculture using flight intercept and pitfall traps baited with human feces, rotten banana and carcass, from December 2005 to November 2006. Twenty-eight species were collected, belonging to 11 genera. Of these 28 species, 11 have been previously recorded in grassland and native forest environments of the region, 11 only in grasslands, two were exclusive of eucalyptus plantations and four were not identified at the specific level, which did not allow the achievement of more information on these species in the natural ecosystems of the region. The results showed that species that occur in eucalyptus are habitat generalists, have preference for shaded environments and/or are tourist species. This, however, is one of the few surveys performed in the region. Therefore, additional studies are necessary to obtain more information about the distribution and response of dung beetles to natural and anthropogenic ecosystems of the region.

Several molecular methods, such as Southern blotting hybridization, Multilocus Sequence Typing, and DNA microsatellite analysis, have been employed to genotype Candida albicans. The genotype analysis allows to group strains in clades, that is, a group composed of one ancestor and its descendants. These genotype studies demonstrate that clades distribution is influenced by geographic area as well as that antifungal resistance is associated with particular clades. These findings suggested that C. albicans reproduces mainly in a clonal manner, with certain degree of DNA microevolution. Additionally, virulence factors and site of isolation have also been associated with clade specificity. The present article is a brief review about the methods used for Candida genotyping and the correlated clade systems established. Special emphasis is given to Ca3 hybridization, MLST, and Microsatellites. The present work is also focused on the phenotypic and physiological traits associated with Candida clades.
