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.

In preparation for tracheal intubation during induction of anesthesia, the patient may be ventilated with 100% oxygen. To investigate the impact of acute isocapnic hyperoxia on endothelial activation and vascular remodeling, ten healthy young men (24±3 years) were exposed to 5-min normoxia (21% O2) and 10-min hyperoxia trials (100% O2). During hyperoxia, intercellular adhesion molecules (ICAM-1) (hyperoxia: 4.16±0.85 vs normoxia: 3.51±0.84 ng/mL, P=0.04) and tissue inhibitor matrix metalloproteinase 1 (TIMP-1) (hyperoxia: 8.40±3.84 vs normoxia: 5.73±2.15 pg/mL, P=0.04) increased, whereas matrix metalloproteinase (MMP-9) activity (hyperoxia: 0.53±0.11 vs normoxia: 0.68±0.18 A.U., P=0.03) decreased compared to the normoxia trial. We concluded that even short exposure to 100% oxygen may affect endothelial activation and vascular remodeling.

Abstract The growth of the population of cattle egrets (Bubulcus ibis) in the archipelago of Fernando de Noronha constitutes a threat to public health and biological diversity because of their competition with and predation on native species and the possibility of transmission of pathogens to human beings, livestock and native wildlife. The aim here was to search for, isolate and identify serovars of Salmonella in clinically healthy local cattle egrets. Cloacal swabs were obtained from 456 clinically healthy cattle egrets of both sexes and a variety of ages. The swabs were divided into 51 pools. Six of these (11.7%) presented four serovars of Salmonella enterica subspecies enterica: Salmonella serovar Typhimurium; Salmonella serovar Newport; Salmonella serovar Duisburg; and Salmonella serovar Zega. One sample was identified as S. enterica subspecies enterica O16:y:-. Results in this study suggest that cattle egrets may be reservoirs of this agent on Fernando de Noronha and represent a risk to public health and biological diversity.

Fractionation of the EtOH extract from aerial parts of Baccharis uncinella C. DC. (Asteraceae) led to isolation of caffeic and ferulic acids, which were identified from spectroscopic and spectrometric evidence. These compounds exhibit antioxidant and anti-inflammatory properties and have been shown to be effective in the prevention/treatment of metabolic syndrome. This study investigated whether the combined treatment of caffeic and ferulic acids exhibits a more significant beneficial effect in a mouse model with metabolic syndrome. The combination treatment with caffeic and ferulic acids was tested for 60 days in C57 mice kept on a high-fat (40%) diet. The data obtained indicated that treatment with caffeic and ferulic acids prevented gain in body weight induced by the high-fat diet and improved hyperglycemia, hypercholesterolemia and hypertriglyceridemia. The expression of a number of metabolically relevant genes was affected in the liver of these animals, showing that caffeic and ferulic acid treatment results in increased cholesterol uptake and reduced hepatic triglyceride synthesis in the liver, which is a likely explanation for the prevention of hepatic steatosis. In conclusion, the combined treatment of caffeic and ferulic acids displayed major positive effects towards prevention of multiple aspects of the metabolic syndrome and liver steatosis in an obese mouse model.

O uso de fitoterápicos é uma alternativa de baixo custo e de fácil acesso para o tratamento de feridas cutâneas. Objetivou-se avaliar a ação do extrato oleoso de urucum na cicatrização de feridas cutâneas abertas. Inicialmente, identificaram-se os principais ácidos graxos do óleo de urucum. Foi realizado ensaio citotóxico para determinar as concentrações a serem utilizadas no ensaio in vivo. No experimento, feridas cutâneas em ratos Wistar foram diariamente tratadas com: extrato de urucum 0,1% (U 0,1%), extrato de urucum 0,01% (U 0,01%), vaselina (V) e solução fisiológica (SF), por até 21 dias. Aos quatro, sete, 14 e 21 dias, foi avaliada clinicamente a presença de exsudato, crosta e epitelização. Determinaram-se as áreas da lesão, e amostras de pele, fígado e rins foram coletadas para avalição histológica. Aos 21dias, amostras de pele foram coletadas para análise tensiométrica. Clinicamente, todos os grupos de tratamento apresentaram evolução cicatricial fisiológica. Os grupos U 0,1% e U 0,01% apresentaram maior presença de epitelização aos sete dias e maior retração cicatricial aos quatro dias. Na histologia, U 0,1% e U 0,01% apresentaram aos quatro e sete dias maior quantidade de fibrina e inflamação que V e SF, e, nos demais momentos, não houve diferenças entre os grupos. Quanto à fase cicatricial, aos quatro dias todos os grupos encontravam-se na fase inflamatória, aos sete dias U 0,1% e U 0,01% permaneciam na fase inflamatória, diferindo de SF e V, que se caracterizavam na fase proliferativa. Aos 14 dias, os grupos apresentavam-se em transição de fase proliferativa para maturação e, aos 21dias, estavam todos na fase de maturação. Os grupos tratados com urucum expressaram menor resistência à tensão que V e SF. Concluiu-se com este estudo que o extrato oleoso de urucum acelera o processo cicatricial nos primeiros dias, mas proporciona uma cicatriz de baixa qualidade.
Phytotherapies are a low cost, easily accessible alternative to traditional medicines in wound healing management. The purpose of this study was to assess the oil extract of Bixa orellana L. as a healing agent in the rat model of open wound healing. Initially, the oil was obtained and characterized through gas chromatography. Furthermore, the cytotoxic potential of the oil was verified in cell cultures to determine the doses used in animal experiments. Wounds were surgically produced in Wistar rats, these were treated with the oil extract at 0.1% (U 0.1%), 0.01% (U 0.01%), petrol jelly (V) and saline (SF) for up to 21 days. At four, seven and 14 days of treatment the wounds were assessed clinically regarding the presence of exudate, crust and epithelialization. The wound area was also determined and skin, kidney and liver tissues were harvested for histopathology. At 21 days of treatment the skins were also harvested for tension resistance assessment. Clinically, all groups evolved similarly, however, those treated with U 0.1% and U 0.01% had a greater amount of epithelialized wounds by day seven, and grater shrinkage by day four. Histopathologicaly, the skin samples of oil treated wounds had more lesions in the inflammatory phase at seven days, when compared to the controls, which were majorly in the proliferation phase. By 14 days no difference was observed among groups, which were all in the transition from the proliferation to the maturation phase. By day 21, all wounds were in the maturation phase. Oil treated wounds also had more fibrin in the first two assessment dates, when compared to the controls. Tension resistance of the oil treated wounds was, however, inferior to that of the controls. This study shows that B. orellana L. oil will hasten the onset of the healing process and its initial phases, but will ultimately produce a scar of poorer quality.

O extrato de trigo (Triticum sp.) vem sendo usado na cicatrização de feridas por estimular a síntese de fibroblastos, entretanto a sua aplicabilidade in vivo em apresentações comercialmente viáveis ainda tem de ser demonstrada. Neste estudo, avaliaram-se feridas cutâneas de coelhos tratadas com extrato aquoso de T. aestivum quanto à presença de tecido de granulação e epitelização, estruturas histológicas, qualidade cicatricial, além de ensaio tensiométrico. As feridas foram tratadas diariamente, por 21 dias, com diferentes concentrações do extrato (grupo I = 2mg/mL; grupo II = 10mg/mL) ou apenas o veículo (grupo controle = creme não iônico), e avaliadas nos dias sete, 14 e 21. A formação de tecido de granulação não diferiu entre os tratamentos. A epitelização aconteceu em menor tempo em feridas do grupo II, mas aos 14 dias já não havia diferença neste parâmetro. Na avaliação histopatológica, a qualidade cicatricial e a força de ruptura não diferiram no período estudado, entretanto a resistência tensiométrica das feridas do grupo I foi maior que a dos demais tratamentos. Dessa forma, conclui-se que, mesmo não havendo diferença na evolução cicatricial de feridas tratadas ou não com extrato aquoso de T. aestivum, o uso desse composto, a 2mg/mL, resultou em tecidos cicatriciais mais resistentes à tração.
While Triticum sp. has been shown to act in wound healing, stimulating collagen synthesis by fibroblasts, the use of this plant extract has yet to be assessed in vivo, in commercially viable presentations. This study used rabbits and assessed, on days seven, 14, and 21, the presence or absence of granulation tissue and epithelialization, histopathological structures, and scar quality through the breaking and tension strength. Treatments, performed for 21 days, were aqueous extract of T. aestivum at a concentration of 2mg/mL (group I) and 10mg/mL (group II) and a nonionic cream (control group). We demonstrate that the formation of granulation tissue was not significantly different between treatments. In the analysis of epithelial tissue, wounds in group II differed from other treatments by day 7. On days 14 and 21 there was no significant clinical difference between groups. In the histopathological evaluation, scar quality and rupture strength did not differ between the groups in the studied period. In the tension strength evaluation, group I differed from the others, presenting a higher tension strength overall. The studied treatments did not differ regarding healing evolution of the skin wounds, but T. aestivum extract, at 2mg/mL, presents better results in the tension strength evaluation.

Este estudo objetivou comparar a concentração de fungos viáveis, especialmente do gênero Aspergillus, no trato respiratório de equinos estabulados com e sem obstrução recorrente das vias aéreas (ORVA). Trinta e dois equinos provenientes de quatro centros de treinamento equestre do Brasil foram incluídos no estudo. Os animais foram submetidos a exame clínico e coleta de amostra respiratória, sendo categorizados em dois grupos: sadios e ORVA. Os lavados traqueobrônquicos obtidos foram avaliados por exame micológico direto e cultivo quantitativo. Ao todo, 18 equinos saudáveis e 14 com ORVA foram estudados. Fungos foram mais frequentemente detectados em amostras do grupo ORVA em comparação com o grupo controle, tanto no exame micológico direto (P<0,0001) e cultivo quantitativo (P<0,0001) quanto na concentração de unidades formadoras de colônias (UFC) de Aspergillus spp. isolada em cultivo (p=0,001). Equinos com ORVA têm maior concentração de propágulos fúngicos no trato respiratório em comparação com animais sadios. As implicações desses achados na patogenia da ORVA merecem maior atenção e investigação.
This study aims to compare the concentration of viable fungi, especially those of the genus Aspergillus in the respiratory tract of stabled horses with and without Recurrent Airway Obstruction (RAO). Thirty two housed horses from four equestrian centers in Brazil were included in the study. These animals were submitted to clinical examination and to a respiratory sample collection. They were categorized into two groups: healthy and RAO-affected horses. Samples obtained by tracheobronchial washes were evaluated for fungal microscopy, quantitative culture and Aspergillus spp. quantification. Eighteen healthy and 14 RAO-affected horses were studied. Fungi were more frequently recovered in the RAO group, in comparison to controls, for both fungal microscopy (P<0.0001), fungal culture (P<0.0001) and Aspergillus spp. quantitative culture (p=0.001). In conclusion, horses with RAO have significantly higher fungal load in the respiratory tract in comparison to healthy horses. The implications of these findings in terms of the pathogenesis of RAO deserve additional investigation.

Avaliaram-se a composição química e a digestibilidade in vitro da matéria seca (DIVMS) do bagaço de cana-de-açúcar hidrolisado com óxido de cálcio em dois períodos. As doses de óxido de cálcio aplicadas ao bagaço foram 0; 1,25; 2,5 e 3,75% (na base da MS) e os períodos de tratamento, 12 e 36 horas. O teor de matéria seca (MS) do bagaço de cana foi maior quando hidrolisado por 36 horas. O valor médio da proteína bruta foi de 2,4% e não foi influenciado pelo período, pela dose de óxido de cálcio nem pela interação período × dose de óxido de cálcio. Os teores de fibra em detergente neutro, fibra em detergente ácido, celulose e lignina diminuíram linearmente com a adição de óxido de cálcio. A digestibilidade in vitro da matéria seca, no entanto, aumentou 1,2% a cada unidade de óxido de cálcio adicionada ao bagaço da cana-de-açúcar. O tratamento com óxido de cálcio por 12 ou 36 horas melhora o valor nutritivo do bagaço de cana-de-açúcar.
The chemical composition and in vitro dry matter digestibility (IVDMD) of sugarcane bagasse hydrolyzed with calcium oxide (CaO) in two periods were evaluated. The doses of calcium oxide applied to bagasse were 0; 1.25; 2.5; and 3.75% (dry matter basis) and the treatment periods were 12 and 36 hours. The dry matter sugarcane bagasse was larger when hydrolyzed for 36 hours. The crude protein mean value observed was 2.4%, with no effects of period, CaO doses, or period and CaO interaction. The neutral detergent fiber, acid detergent fiber, celluloses, and lignin levels linearly reduced with CaO added. The IVDMD increased with CaO add, estimating increase of 1.2% for each CaO unit added to sugarcane bagasse. The periods of 12 or 36 hours can be adopted to sugarcane bagasse treatment with CaO. The CaO addiction to sugarcane bagasse improve its nutritive value.

Em vastas áreas do Alentejo, os solos sob pastagem natural apresentam baixa fertilidade. A aplicação de lama residual urbana (LRU) veicula matéria orgânica (M.O.) e nutrientes para o solo, mas também pode introduzir metais pesados e bactérias de origem fecal, pelo que é conveniente monitorizar o solo após a adição destes resíduos. Comparam-se as fertilizações orgânica com LRU e a mineral, nos efeitos em alguns índices de fertilidade e contaminação metálica e fecal de um solo derivado de xistos e grauvaques, no Alentejo, no 1º ano de um campo experimental com pastagens. O campo, com um esquema experimentalem “split-plot”, foi constituído por seis talhões de 0,5 ha, correspondentes a três tratamentos de fertilização (nula, mineral e orgânica, com LRU), em dois tipos de pastagem, natural e semeada. Aplicaram-se cerca de 13 t/ha de uma mistura de LRU das ETARs de tratamento secundário de Alvito e de Vila Nova de Baronia, com teores apreciáveis de M.O., N e Ca. A adubação incluiu N, P, K, Zn e Mo. Determinaram-se os valores de pH (H2O) e os teores de M.O. total, N total, P e K “assimiláveis”, catiões de troca e de Cd, Cr, Cu, Ni, Pb e Zn extraíveis por água régia, em amostras de terra (fracção < 2 mm), colhidas à profundidade de 0-15/20 cm, antes da aplicação dos fertilizantes e cerca de um ano após a incorporação dos mesmos no solo. Para a prospecção de indicadores microbianos de contaminação fecal (bactérias coliformes e Enterococcus), efectuaram-se três amostragens de terra (0-5/10 cm), imediatamente após a aplicação de LRU e seis e 13 meses depois, nas modalidades com e sem aplicação do resíduo. Para ambos os tipos de pastagem, a aplicação de LRU beneficiou nitidamente a camada superficial do solo quanto ao teor de M.O., um ano após a aplicação dos fertilizantes, não tendo alterado o nível inicial de metais pesados ou de bactérias de origem fecal.
In wide areas of Alentejo, soils under natural pasture have low fertility. Urban biosolids (UB) application introduce organic matter (O.M.) and nutrients in the soil, but it can also add heavy metals and bacteria of faecal origin. Thus, soil monitoring after the application of these residues is required. Organic with UB and mineral fertilisations were compared regarding their effects on some fertility and metallic and faecal pollution indicators of a soil derived from schists and grauwacks, in the 1st year of a field experiment with pastures. The experimental layout was a split-plot design, with six plots of 0.5 ha, referring to three fertilisation treatments (“nil”, mineral, and organic, with UB), in natural and sown pastures. The UB application was about 13 t/ha of a UB mixture from the Alvito and Vila Nova de Baronia plants, rich in O.M., N, and Ca. Mineral fertilisation included N, P, K, Zn, and Mo. Soil samples (fraction <2 mm) collected at the 0-15/20 cm depth, before the fertilisers application and around one year after the establishment of the experiment were analysed for pH (H2O) value and O.M., total N, available P and K, exchangeable cations, and extractable aqua regia Cd, Cr, Cu, Ni, Pb, and Zn. Microbial indicators of faecal contamination (coliform bacteria and enterococci) were also evaluated from topsoil samples (0-5/10 cm), collected immediately after the UB application, and 6 and 13 months afterwards, in the treatments with and without UB application. For both types of pasture, the UB application significantly improved the O.M. content in the soil surface layer, one year after the fertiliser application, and did not change the initial soil levels of heavy metals and bacteria populations of faecal origin.

RESUMO Frente ao crescente interesse em ecologia e conservação da fauna silvestre, o diagnóstico e tratamento de entidades nosológicas pertinentes aos animais não domésticos, mantidos em cativeiro, tem sido solicitado aos médicos veterinários e apesar disso, raros são os trabalhos publicados enfocando a microbiota de animais silvestres. É sabido que várias espécies fúngicas sapróbias são isoladas de pele, pêlos e conduto auditivo de animais domésticos, podendo em situações específicas serem potêncialmente patogênicos. Objetivou-se neste trabalho identificar as espécies de fungos em pele, pêlos e conduto auditivo de macacos bugio (Alouatta caraya), sagüis (Callithrix sp.) e macacos prego (Cebus apella) clinicamente saudáveis. As amostras foram obtidas por retirada de pêlos e descamação cutânea. E, ainda, realização de impressão em lâmina de vidro no pavilhão auricular de 16 bugios, 12 sagüis e 27 macacos prego apreendidos pelo Centro de Triagem e Quarentena do Reservatório de Manso, MT. No Laboratório de Microbiologia do Hospital Veterinário da Universidade de Cuiabá, o material foi processado visando a identificação fúngica. Evidenciou-se o desenvolvimento fúngico em 7 (43,75%) amostras provenientes de bugio, sendo, respectivamente, Curvularia sp.(12,5%), Drechslera sp. (6,25%), Penicillium sp. (6,25%), Cladosporium sp. (6,25%), Aspergillus sp. (6,25%), Fusarium sp.(6,25%). Das amostras provenientes de sagüi, 5 (41,67%) resultaram positivas, respectivamente, para Aspergillus sp.(16,65%), Drechslera sp. (8,34%), Rhodotorula sp. (8,34%), Curvularia sp. (8,34%). Em macacos prego, 7 (25,92%) amostras foram positivas, respectivamente, para Curvularia sp. (14,82%), Aspergillus sp. (7,4%) e Cladosporium sp. (3,7%). Na citologia para diagnóstico de Malassezia pachydermatis, encontrou-se células leveduriformes características em 1 (8,3%) sagüi, 3 (18,74%) bugios e 6 (22,23%) macacos prego. Frente aos resultados obtidos concluiu-se que os fungos isolados provavelmente são integrantes da microbiota normal dos animais, bem como ficou evidente a ocorrência de leveduras em grande número de animais. silvestre domésticos cativeiro disso silvestres pele patogênicos Objetivouse Objetivou se Alouatta caraya, caraya , caraya) Callithrix sp Cebus apella saudáveis cutânea E ainda 2 Manso MT Cuiabá fúngica Evidenciouse Evidenciou 43,75% 4375 43 75 (43,75% sendo respectivamente sp.12,5%, sp125 12,5% sp.(12,5%) 6,25%, 625 6,25% 25 (6,25%) sp.6,25%. sp625 . sp.(6,25%) sagüi 41,67% 4167 41 67 (41,67% positivas sp.16,65%, sp1665 16,65% 65 sp.(16,65%) 8,34%, 834 8,34% 8 34 (8,34%) 8,34%. 25,92% 2592 92 (25,92% 14,82%, 1482 14,82% 14 82 (14,82%) 7,4% 74 4 (7,4% 3,7%. 37 3,7% (3,7%) pachydermatis encontrouse encontrou 8,3% 83 (8,3% 18,74% 1874 18 (18,74% 22,23% 2223 22 23 (22,23% concluiuse concluiu 43,75 437 (43,75 sp.12,5% sp12 125 12,5 sp.(12,5% 62 6,25 (6,25% sp.6,25% sp62 sp.(6,25% 41,67 416 (41,67 sp.16,65% sp166 1665 16,65 sp.(16,65% 8,34 (8,34% 25,92 259 9 (25,92 148 14,82 (14,82% 7,4 (7,4 3,7 (3,7% 8,3 (8,3 18,74 187 (18,74 22,23 222 (22,23 43,7 (43,7 sp.12,5 sp1 12, sp.(12,5 6,2 (6,25 sp.6,25 sp6 sp.(6,25 41,6 (41,6 sp.16,65 sp16 166 16,6 sp.(16,65 (8,34 25,9 (25,9 14,8 (14,82 7, (7, 3, (3,7 8, (8, 18,7 (18,7 22,2 (22,2 43, (43, sp.12, sp.(12, 6, (6,2 sp.6,2 sp.(6,2 41, (41, sp.16,6 16, sp.(16,6 25, (25, 14, (14,8 (7 (3, (8 18, (18, 22, (22, (43 sp.12 sp.(12 (6, sp.6, sp.(6, (41 sp.16, sp.(16, (25 (14, ( (3 (18 (22 (4 sp.1 sp.(1 (6 sp.6 sp.(6 sp.16 sp.(16 (2 (14 (1 sp.(
ABSTRACT Due to the growing interest in ecology and preservation of wild animals, veterinary doctors have been asked to diagnose and treat nosologic entities pertaining to non-domestic animals that are kept in captivity. In spite of this, very few studies have been published focusing on the microbiota of wild animals. It is known that several saprobic fungus species are isolated from the hide, hair and auditory canal and these can, in specific situations, be potentially pathogenic. This study was aimed at identifying the species of fungus on the hide, hair and auditory canal of clinically healthy howling monkeys (Alouatta caraya), marmosets (Callithrix sp.), and capuchin monkeys (Cebus apella). The samples were obtained by extraction of hair and cutaneous exfoliation and glass lamina impression on the auricular pavilion of 16 howling monkeys, 12 marmosets, and 27 capuchin monkeys, captured by the Screening and Quarantine Center of the Manso Reservoir in Mato Grosso. At the Microbiology Laboratory of the University of Cuiabá Veterinary Hospital the material was processed for fungus identification. There was fungus development in 7 (43.74%) samples taken from howling monkeys, being, respectively, Curvularia sp. (12.5%), Drechslera sp. (6.25%), Penicillium sp. (6.25%), Cladosporium sp. (6.25), Aspergillus sp. (6.25%) and Fusarium sp. (6.25%). From the samples taken from marmosets, 5 (41.67%) were positive for > Aspergillus sp. (16.65%), Drechslera sp. (8.34%), Rhodotorula sp.

The objective of the present study was to investigate the influence of the establishment of dominance relationships and social stress on plasma cortisol and metabolite levels in Nile tilapia (Oreochromis niloticus). During the 30-day experiment, the fish weighing 236 ± 29 g were kept in individual aquaria, except for two pairings lasting 6 h each. Blood samples were taken from the animals before and after pairing. Display, approach, attack, rebuff, chase flight, and coloration were carried out on days 16 and 30. Activities and behaviors characteristic of the establishment of dominance relationships were described. It was possible to classify all experimental fish (N = 30) as dominant or subordinate. No differences were detected between dominant (N = 15) and subordinate (N = 15) fish during isolation or after pairing in cortisol (isolated: 5.76 ± 0.98 vs 5.42 ± 0.63; paired: 10.94 ± 1.62 vs 11.21 ± 2.45 µg/dl), glucose (isolated: 60.02 ± 4.9 vs 67.85 ± 16.16; paired: 110.44 ± 15.72 vs 136.26 ± 22.46 mg/dl), triglyceride (isolated: 167.87 ± 5.06 vs 185.68 ± 7.24; paired: 210.85 ± 13.40 vs 221.82 ± 12.70 mg/dl) or total protein levels (isolated: 7.01 ± 0.42 vs 6.69 ± 0.59; paired: 9.21 ± 0.62 vs 9.51 ± 0.66 g/dl). However, when isolated (N = 30) and paired (N = 30) tilapia were compared, there were significant differences in cortisol and metabolite levels. The similar response presented by dominant and subordinate tilapia indicates that establishment of dominance relationships was a stressor for both groups.

A ocorrência de S. Enteritidis, no Estado de São Paulo, Brasil, tem aumentado acentuadamente desde 1994. Um total de 105 cepas de S. Enteritidis (72 de origem humana e 33 de fontes não humanas), isoladas durante o período 1975-1995, previamente caracterizadas por fagotipagem, foram analisadas para: susceptibilidade aos antimicrobianos, perfil plasmidial e ribotipagem. Aproximadamente 70% das cepas foram susceptíveis aos agentes antimicrobianos testados, porém multirresistência foi principalmente observada, entre aquelas cepas isoladas de pacientes hospitalizados. No período de 1975-1992 verificou-se o predomínio do fagotipo 8 (PT-8), porém, nos anos seguintes, PT-4 foi o fagotipo predominante. Sete diferentes perfis plasmidiais foram detectados e 96% das cepas albergavam um plasmídio de aproximadamente 36 MDa. A ribotipagem discriminou 14 ribotipos (R1 a R14) entre as cepas examinadas. Pela análise do dendrograma, as cepas foram incluídas em três grupos com nível de similaridade de 60%. Os resultados obtidos indicam que um único ribotipo (R11), determinado para as cepas PT-4 isoladas a partir de 1993, caracteriza o clone epidêmico de S. Enteritidis em nossa região
In São Paulo State, Brazil, the epidemic increase in isolation of Salmonella Enteritidis has been observed since 1994. A total of 105 S. Enteritidis strains (72 from human and 33 from non-human sources) isolated during the period 1975-1995, previously characterized by phage typing, was analyzed by antimicrobial susceptibility, plasmid profile, and ribotyping. Over 70% of the strains were susceptible to all antimicrobial agents tested, however, multiple resistance to antimicrobials was observed among the studied strains, mainly those from hospitalized patients. Phage type 8 (PT-8) was predominant among the strains isolated during the period of 1975-1992, but in the following years, PT-4 was the most frequent phage type identified. Seven different plasmid profiles were detected and 96% of the isolates harbored a plasmid of approximately 36 MDa. Ribotyping discriminated fourteen ribotypes (R1 to R14) among the strains examined. By analysis of dendrogram the strains were included in three groups with similarity level of 60%. The obtained results indicate that, a single ribotype (R11), determined for PT-4 strains isolated from 1993, characterizes the epidemic clone of S. Enteritidis in our region.
