RESUMO Dentre os ajustes fitotécnicos necessários, a correta recomendação da população de plantas de cada cultivar de soja é de suma importância para o sucesso na produção desta cultura. Assim, o objetivo deste estudo foi analisar a distribuição e autocorrelação espacial da população de plantas de soja de acordo com a variabilidade espacial de atributos físicos e químicos de um Latossolo na região do Cerrado brasileiro. Os atributos estudados foram: população de plantas, produtividade de grãos de soja, condutividade elétrica aparente do solo, teor de matéria orgânica do solo, capacidade de troca catiônica, potencial hidrogeniônico e teor de argila no solo. A população de plantas variou inversamente em função da condutividade elétrica aparente do solo. As áreas com os maiores valores de condutividade elétrica aparente do solo, teor de matéria orgânica do solo, capacidade de troca catiônica e teor de argila apresentaram as menores populações de plantas. A produtividade da soja não foi influenciada pelo aumento ou diminuição da população de plantas, por isso é economicamente viável plantar com menor densidade de plantas para melhorar a margem de lucro do agricultor. necessários cultura Assim brasileiro foram solo agricultor
ABSTRACT Among the necessary phytotechnical adjustments, the correct recommendation of the plant population of each soybean cultivar is of paramount importance for success in crop production. Thus, the objective of this study was to analyze the distribution and spatial autocorrelation of the soybean plant population according to the spatial variability of the physical and chemical attributes of Oxisol in the Brazilian Cerrado region. The attributes studied were plant population, soybean grain yield, apparent soil electrical conductivity, soil organic matter content, cation exchange capacity, hydrogenionic potential, and clay content in the soil. The plant population varied inversely as a function of apparent soil electrical conductivity. The areas with the highest values of apparent soil electrical conductivity, soil organic matter content, cation exchange capacity, and clay content had the lowest plant populations. Soybean yield was not influenced by increase or decrease in the plant population. Thus, it is economically viable to plant with lower plant density to improve the farmer’s profit margin. adjustments production Thus region conductivity capacity potential populations farmers farmer s margin

Abstract This research was conducted for the purpose to evaluate the contribution Giant petrels and Brown skuas nestings in the formation of ornithogenic soils by the phosphatization process in Harmony Point, Maritime Antarctic. Ten nests were selected to collect topsoil samples (0-20 cm), from 0 m up to 20 m away, with regular spacing of 2 m. The analysis of the samples included the physical, chemical, mineralogical and geochemical analyzes. Phosphate minerals were identified. The presence of high content of some trace elements, such as Zn, Cu and Sr is associated with the bird’s excrements. Total-P and bioavailable-P recorded higher levels. This result demonstrates the importance of the time factor in the bird’s nesting, as well as in the development of the soil in these soil-forming environment. Phosphatization in these areas is not restricted to the specific location of the nest, since high values of P have been identified at distances between 8 and 12 m, from de nest’s top. This suggests the transport of P rich solutions and phosphatized material along fractures by the freeze-thaw cycles, contributing to increase the geographical expression of this phenomenon in this ice-free area, consequently the development of soils and the establishment of vegetation.

RESUMO A caracterização da resistência de plantas daninhas a herbicidas, bem como os estudos sobre os mecanismos de resistência e as alternativas para o controle químico são fundamentais para o manejo de plantas daninhas resistentes a herbicidas. Desta forma, este trabalho teve como objetivo reportar e elucidar o mecanismo de resistência de um biótipo de Raphanus raphanistrum a inibidores da acetolactato-sintase (ALS). Foram desenvolvidos trabalhos de dose resposta, sequenciamento do gene ALS, verificação de metabolização e alternativas para o controle químico. Ocorreu baixa eficiência de controle de herbicidas inibidores de ALS a esse biótipo, sendo confirmada a resistência cruzada. O sequenciamento gene ALS demostrou que o biótipo apresentou a mutação Try-574-Leu, já reportada na literatura e que confere resistência cruzada a este mecanismo de ação. O ensaio para verificação de metabolização provou que esse mecanismo não está envolvido na resistência. Já o estudo de controle químico indicou que existem alternativas para o controle do biótipo resistente. Conclui-se que o biótipo de nabiça apresentou resistência cruzada aos herbicidas inibidores de ALS, com a mutação Try-574-Leu na enzima alvo e que herbicidas de outros mecanismos de ação promovem elevada eficiência de controle. forma acetolactatosintase acetolactato sintase ALS. .

ABSTRACT Understanding how weeds resist herbicides, their resistance mechanisms, and alternative control methods are crucial for managing herbicide-resistant weeds. This study aims to unravel the resistance mechanism of a Raphanus raphanistrum biotype to acetolactate synthase (ALS) inhibitors. To this end, dose-response studies, DNA sequencing, and metabolic pathway verification were conducted. ALS-inhibiting herbicides showed low efficacy in controlling this biotype, confirming cross-resistance. Sequencing of the ALS enzyme revealed the presence of the previously reported Try-574-Leu mutation, known to confer cross-resistance to this mode of action. However, the metabolization verification assay demonstrated that this mechanism did not contribute to the observed resistance. Chemical control studies with alternative herbicides yielded promising results, indicating the potential for effective management of the resistant biotype. Our findings showed that the wild radish biotype used exhibits cross-resistance to ALS-inhibiting herbicides due to the presence of the Try-574-Leu mutation in the target enzyme. Notably, herbicides with alternative mechanisms of action prove highly effective in controlling this resistant biotype, offering valuable options for weed management strategies. herbicideresistant herbicide (ALS inhibitors end doseresponse dose response sequencing conducted ALSinhibiting inhibiting crossresistance. crossresistance cross Try574Leu TryLeu Try 574 Leu However results Notably strategies 57 5

ABSTRACT: In the last decade, there has been a significant increase in the demand for small rodents such as hamsters, guinea pigs, rats, and mice to be kept as pets. Consequently, the veterinary care provided to these animals has also increased. The aim of this study was to describe gross, histopathological and immunohistochemical findings of 26 spontaneous neoplasms diagnosed in 25 pet rodents in Northeastern Brazil. A retrospective study was carried out from 2014 to 2022 in two veterinary diagnostic laboratories to identify cases of tumoriform lesions in these species. Hamsters represented the most frequent species in this study (60%, 15/25), followed by rats (28%, 7/25), guinea pigs (8%, 2/25), and mice (4%, 1/25), with a mean age of 17.63 months. The anatomical regions of the face/head and thoracic region were the most affected. The most affected tissues were the skin/subcutaneous/mucosal (65%, 15/26) and mammary gland (23%, 6/26). Eighteen different types of neoplasms were diagnosed, and T-cell lymphomas and mammary adenocarcinomas were the most diagnosed tumors, each corresponding to 12% (3/26) of the cases. Leiomyosarcoma, myxosarcoma and mammary adenocarcinoma metastases were also noted. Immunohistochemistry was essential for the diagnosis of certain malignant mesenchymal and round-cell neoplasms. Pet rodent neoplasms in Northeastern Brazil are common, especially in hamsters, and immunohistochemistry can be a useful tool for the definitive diagnosis of these tumors.

ABSTRACT This study aimed to provide further insight into the evolutionary dynamics of SARS-CoV-2 by analyzing the case of a 40-year-old man who had previously undergone autologous hematopoietic stem cell transplantation due to a diffuse large B-cell lymphoma. He developed a persistent SARS-CoV-2 infection lasting at least 218 days and did not manifest a humoral immune response to the virus during this follow-up period. Whole-genome sequencing and viral cultures confirmed a persistent infection with a replication-positive virus that had undergone genetic variation for at least 196 days after symptom onset.

Molecular and periodic allotropes based on cyclo[18]carbon, known as archicarbons, were investigated using density functional theory (DFT) in both molecular and periodic models. This study explores the physicochemical characteristics of these exquisite carbon allotropes, including various molecular archicarbons (spiro[18]carbon, bicyclo[8]carbon, 0-tricyclo[8] carbon, 0-bi(cyclo[19]carbon), l-bi(cyclo[19]carbon), and 0-fused[18]carbon) and periodic archicarbons (poly-spiro[8]carbon, poly-0-bi(cyclo[8]carbon), poly-l-bi(cyclo[8]carbon)). Most proposed molecular archicarbons showed higher cohesive energy than cyclo[18]carbon, except for bicyclo[8]carbon, which suggests that those may be experimentally observable. Proposed synthetic routes for both molecular and periodic archicarbons are suggested, highlighting their potential, particularly in semiconductor applications, and paving the way for further exploration of their distinct electronic properties. cyclo18carbon, cyclo18carbon cyclocarbon cyclo 18 cyclo[18]carbon DFT (DFT models spiro18carbon, spiro18carbon spirocarbon spiro (spiro[18]carbon bicyclo8carbon, bicyclo8carbon bicyclocarbon bicyclo 8 bicyclo[8]carbon 0tricyclo8 tricyclo 0 0-tricyclo[8 0bicyclo19carbon, 0bicyclo19carbon bi 19 , 0-bi(cyclo[19]carbon) lbicyclo19carbon, lbicyclo19carbon lbicyclocarbon l l-bi(cyclo[19]carbon) 0fused18carbon fusedcarbon fused 0-fused[18]carbon polyspiro8carbon, polyspiro8carbon polyspirocarbon poly (poly-spiro[8]carbon poly0bicyclo8carbon, poly0bicyclo8carbon polybicyclocarbon poly-0-bi(cyclo[8]carbon) polylbicyclo8carbon. polylbicyclo8carbon polylbicyclocarbon . poly-l-bi(cyclo[8]carbon)) observable suggested potential applications properties 1 0tricyclo 0-tricyclo[ 0-bi(cyclo[19]carbon lbicyclo l-bi(cyclo[19]carbon polyspiro poly-0-bi(cyclo[8]carbon polylbicyclo poly-l-bi(cyclo[8]carbon) 0-tricyclo poly-l-bi(cyclo[8]carbon

RESUMO A adubação do capim-elefante é realizada de forma mais eficiente ao analisar as curvas de crescimento e acúmulo de nutrientes. Com isso, objetivou-se avaliar o crescimento, a produção de matéria seca e os acúmulos de nutrientes do capim-elefante. Foi utilizado um delineamento de amostragem, com coletas de plantas ao longo do tempo. O capim-elefante foi conduzido em quatro parcelas de 27 m2, durante dois ciclos de cultivo. Foram realizadas amostragens destrutivas de quatro plantas por coleta, para avaliar a produção de matéria seca e os acúmulos de nutrientes. No primeiro ciclo, as plantas foram coletadas aos 21, 35, 49, 63, 77, 91, 105 e 119 dias após o plantio. Após a última coleta do primeiro ciclo, foi realizado um corte de uniformização, eliminando as plantas restantes nas parcelas experimentais. O segundo ciclo de coletas ocorreu aos 21, 35, 49, 63, 77, 91 e 105 dias após corte de uniformização. Em todas as coletas foi realizada a contagem do número de perfilhos por metro linear e avaliada a altura das plantas. Os dados foram submetidos à análise de regressão não linear. O acúmulo de nutrientes pelo capim-elefante acompanhou a produção de matéria seca. As maiores taxas na produção de matéria seca ocorreram por volta dos 70 dias. O período de maior crescimento em altura ocorreu dos 18 aos 102 dias no 1º ciclo, e dos 8 aos 61 dias no 2º ciclo. O acúmulo de nutrientes apresentou a seguinte ordem decrescente: K>N>Mg>Ca>P>S>Fe>Mn>Zn>Cu (1º ciclo); e, K>N>Mg>Ca>P>S>Fe>Zn>Mn>Cu (2º ciclo). capimelefante capim elefante isso objetivouse objetivou se capimelefante. elefante. amostragem tempo 2 m2 m cultivo 21 35 49 63 77 10 11 plantio uniformização experimentais 9 7 1 º 6 decrescente KNMgCaPSFeMnZnCu K N Mg Ca P S Fe Mn Zn Cu ciclo) KNMgCaPSFeZnMnCu . 3 4
ABSTRACT Elephant grass fertilization is performed more efficiently by analyzing growth curves and nutrient accumulation. This study evaluated elephant grass's growth, dry matter production, and nutrient accumulation. A sampling design was used, with plant collections over time. Elephant grass was cultivated in four plots of 27 m2 during two cultivation cycles. Destructive sampling of four plants was carried out per collection to evaluate dry matter production and nutrient accumulations. In the first cycle, plants were collected at 21, 35, 49, 63, 77, 91, 105 and 119 days after planting. After the last collection of the first cycle, a standardization cut was made, eliminating the remaining plants in the experimental plots. The second cycle of collections was carried out at 21, 35, 49, 63, 77, 91, and 105 days after the uniformity cut. In all collections, the number of tillers per linear meter was counted, and the height of the plants was evaluated. The data were subjected to nonlinear regression analysis. The accumulation of nutrients by elephant grass accompanied the production of dry matter. The highest rates of dry matter production occurred around 70 days. The greatest height growth occurred from 18 to 102 days in the 1st cycle and 8 to 61 days in the 2nd cycle. Nutrient accumulation showed the following decreasing order: K>N>Mg>Ca>P>S>Fe>Mn>Zn>Cu (1st cycle); and K>N>Mg>Ca>P>S>Fe>Zn>Mn>Cu (2nd cycle). grasss s used time 2 m cycles accumulations 21 35 49 63 77 91 10 11 planting made counted analysis 7 1 st 6 nd order KNMgCaPSFeMnZnCu K N Mg Ca P S Fe Mn Zn Cu cycle) KNMgCaPSFeZnMnCu . 3 4 9

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.

RESUMO Esta pesquisa objetivou avaliar a eficiência de uso de fósforo em genótipos de meloeiro cultivados em sistema hidropônico. Foram avaliados 10 genótipos de meloeiro em soluções nutritivas com e sem restrição de fósforo. Utilizou-se o delineamento em blocos casualizados no esquema fatorial 10 × 2, com cinco repetições. Foram avaliados os seguintes caracteres: número de folhas, diâmetro do caule, comprimento do ramo principal, comprimento do sistema radicular, volume do sistema radicular, clorofila, razão do teor de fósforo na raiz e parte aérea, fósforo total, razão da matéria seca na raiz e parte aérea, matéria seca total e eficiências de uso, de aquisição e de utilização interna de fósforo. Verificou-se a existência de variabilidade entre os genótipos para todos os caracteres avaliados, exceto para clorofila. Os genótipos A-16, A-29, A-50, A-52 e Trinity foram classificados como eficientes e responsivos na solução com restrição de fósforo, sendo promissores para estudos em melhoramento genético.
ABSTRACT This study aimed to evaluate the efficiency of phosphorus use with melon genotypes cultivated in a hydroponic system. Ten melon genotypes were evaluated in solutions with and without phosphorus restriction. A randomized block design in a 10 × 2 factorial scheme was used, with five replicates. The following characteristics were evaluated: leaf number, stem diameter, main branch length, root system length, root system volume, chlorophyll, root and shoot phosphorus concentration ratio, total phosphorus, root and shoot dry matter ratio, total dry matter, and phosphorus use, acquisition, and internal utilization efficiencies. The existence of variability among genotypes was verified for all evaluated characteristics, except for chlorophyll. Genotypes A-16, A-29, A-50, A-52, and Trinity were classified as efficient and responsive in the phosphorus-restricted solution and are promising for breeding studies.

Abstract The objective of this work was to evaluate the temperament of Canchim calves using different methods, to compare these methods, and to determine the most suitable for commercial use. The temperament of 1,831 calves was evaluated at 15 days after weaning by visually analyzing movement, tension, breathing, vocalizing, and kicking. Measurements were taken at 10 and 20 s after the calf entered the scale. The reactivity score was determined electronically, and flight speed was measured after the calf left the scale. The results of the principal component analysis showed that the first component explained 40.27% of total variation. Positive correlations were found for tension at 10 and 20 s, movement at 10 and 20 s, and reactivity score, with correlation coefficients ranging from 0.60 to 0.88. Temperament and reactivity scores presented moderate correlations of 0.25 and 0.35, respectively, with flight speed. However, kicking had no correlation with any variable. No differences were observed for reactivity measured at 10 or 20 s. The visual evaluations of movement and tension or of reactivity through an electronic device can be used for temperament evaluation of Canchim calves. methods use 1831 1 831 1,83 breathing vocalizing 2 scale electronically 4027 40 27 40.27 variation 060 0 60 0.6 088 88 0.88 025 25 0.2 035 35 0.35 respectively However variable 183 83 1,8 402 4 40.2 06 6 0. 08 8 0.8 02 03 3 0.3 18 1, 40.

Abstract Areas of high concentration of seal carcasses have been observed in localized areas of James Ross Island, Antarctica. Such carcasses show an unusual vegetation development, in a semi-arid area with bare soils under intense winds, high salinity and sandy texture. We investigated carcasses of seals around a lake in James Ross Island, with four different stages of decomposition, with three replicates: Seal (S01), with recently mummified carcasses; S02, with partially degraded carcasses; S03, with broken carcasses with partially degraded exposed bones, and S04, with completely broken, scattered skeletons. The vegetation showed a maximum degree of development in carcasses at stages S02 and S03, with the environment between the skin and the skeleton as the preferred place for vegetation establishment. The chemical alteration was greater with increasing carcass decomposition but reduced with the spreading and final decomposition of the bones, with anomalous values observed only in the vicinity of the carcasses. It is concluded that the presence of carcasses of seals, concentrated in wet places, even in a semi-desert climate, represent important oases of nutrients, with a combination of physical and chemical effects throughout the decomposition process that favor plant establishment and succession.

Abstract This article carried out the first scientometric and spatial analysis of Brazilian scientific production on Antarctic soils and permafrost, based on all publications available from the Scopus and Web of Science databases. Information on co-authorship, citation, research topics, and sampling sites was used to understand the social and theoretical structure as well as the spatial dynamics of this research field in Brazil over the last 25 years. We highlight that Brazil is presently, the main country to study the soils and permafrost of Maritime Antarctica, in addition to having an international robust and prolific production, with high impact on the literature, and widely distributed throughout the studied region. It was also possible to identify potential future international partners, new research locations and strategic research themes. databases coauthorship, coauthorship co authorship, authorship co-authorship citation topics 2 years presently Antarctica literature region partners themes

RESUMO: Este estudo realizou a caracterização de coccidiose em frangos de corte e avaliou a ocorrência de casos sugestivos de enterite necrótica (EN), buscando se há alguma associação entre estas duas enfermidades em lotes de frango de corte no Brasil. Foram avaliadas 256 aves de 32 lotes. Lesões macroscópicas e histopatológicas foram graduadas para coccidiose e EN. O conteúdo intestinal foi investigado por reação em cadeia da polimerase (PCR) para sete espécies de Eimeria e por cultura anaeróbia seletiva para Clostridium perfringens e identificação do gene NetB. Os lotes positivos para coccidiose representaram 93,8%. Lesões macroscópicas de coccidiose foram de Grau 1 para E. acervulina (27%); E. tenella (9,7%) e E. maxima (8,9%). A avaliação histopatológica mostrou Grau 1 no duodeno (38,2%); jejuno (21,4%); ceco (9,3%) e íleo (5%). A PCR demonstrou positividade para E. tenella (21,9%), E. maxima (18,8%) e E. acervulina (3,1%). Lesões macroscópicas sugestivas de enterite necrótica variaram de grau 1 (16%), 2 (23%) e 3 (10,9%). A histopatologia indicou ausência de necrose, apresentando apenas hemorragia em mucosa e submucosa, com presença de Eimeria spp. Clostridium perfringens tipo A netB + não foi isolado, demonstrando que lesões macroscópicas encontradas principalmente no jejuno não caracterizaram NE, com base na histopatologia e negatividade do gene NetB. O estudo sugere que, em virtude da alta ocorrência de coccidiose nos lotes, muitos achados macroscópicos sugestivos de EN são, na verdade, atribuídos a lesões atípicas provocadas pela reprodução de Eimeria spp. RESUMO EN, , (EN) Brasil 25 (PCR NetB 938 93 8 93,8% E 27% 27 (27%) 9,7% 97 9 7 (9,7% 8,9%. 89 8,9% .

ABSTRACT: This study performed the characterization of coccidiosis in broilers and evaluated the occurrence of suggestive cases of necrotic enteritis (NE), seeking if there is an association between the diseases in Brazilian flocks. Two hundred and fifty-six birds from 32 flocks were evaluated. Macroscopic and histopathological lesions were graduated for coccidiosis and NE. Intestinal content was investigated by polymerase chain reaction (PCR) for seven species of Eimeria and by selective anaerobic culture for Clostridium perfringens and identification of the NetB gene. Flocks positive for coccidiosis represented 93.8%. Macroscopic lesions of coccidiosis were Grade 1 for E. acervulina (27%); E. tenella (9.7%) and E. maxima (8.9%). Histopathological evaluation showed Grade 1 in duodenum (38.2%); jejunum (21.4%); cecum (9.3%) and ileum (5%). PCR demonstrated positivity for E. tenella (21.9%), E. maxima (18.8%), and E. acervulina (3.1%). Suggestive macroscopic lesions of necrotic enteritis ranged from Grade 1 (16%), 2 (23%) and 3 (10,9%). Histopathology indicated the absence of necrosis, showing only hemorrhage in the mucosa and submucosa, with the presence of Eimeria spp. Clostridium perfringens type A netB+ was not isolated, demonstrating that macroscopic lesions found mostly in the jejunum did not characterize NE, based on histopathology and negativity of the NetB gene. The study suggests that, due to the high occurrence of coccidiosis, many macroscopic findings suggestive of NE are, in fact, attributed to atypical lesions caused by the reproduction of Eimeria spp. ABSTRACT , (NE) fiftysix fifty six (PCR gene 938 93 8 93.8% E 27% 27 (27%) 9.7% 97 9 7 (9.7% 8.9%. 89 8.9% .

Abstract This study evaluated the technological viability of yogurt with the addition of green-banana biomass (Musa spp.) considering the resistant starch (BBV) as a potential prebiotic ingredient and texture agent. Four yogurt formulations were prepared: control; 3% BBV; 5% BBV; and 10% BBV. They were subjected to analysis of resistant starch, lactose, fat, total dry extract, defatted dry extract, moisture, ash, proteins, pH and titratable acidity; syneresis analysis, instrumental texture and instrumental color. All four formulations met the requirements of the identity and quality regulation for fermented milks regarding the physicochemical and microbiological parameters. In the instrumental color analysis, in all treatments with added BBV, darkening was observed after 21 days, with a reduction of a* coordinate and an increase of b* coordinate. In the instrumental texture analysis, the yogurt in the Control treatment had the highest firmness (0.430 N) at 21 days among these treatments. Among the treatments with added BBV, the yogurt with 5% added BBV showed the best results for increasing the viability of lactic bacteria. It was found that yogurt with added BBV is a promising alternative in the elaboration of functional dairy products, adding value to the banana production chain by reducing the green fruit waste. greenbanana Musa spp. spp (BBV agent prepared control 3 5 10 lactose fat extract moisture ash proteins acidity parameters 2 b 0.430 0430 0 430 (0.43 N bacteria products waste 1 0.43 043 43 (0.4 0.4 04 4 (0. 0.

RESUMO: O presente estudo investigou a ocorrência de Salmonella spp. em fezes de 200 potros com até um ano de idade (100 com sinais clínicos de diarreia e 100 sem sinais clínicos de diarreia), utilizando as técnicas de cultivo bacteriológico e PCR em tempo real (qPCR) pelos métodos de corante fluorescente (SYBR® Green) e sonda específica (Taqman®) para a detecção do gene invA com e sem etapa de pré-enriquecimento seletivo em caldo de tetrationato. O cultivo bacteriológico revelou 15% (n=30) de animais positivos (21 animais com diarreia e nove animais sem diarreia). Dentre esses 30 isolados, 13 sorovares diferentes foram identificados: S. Infantis, S. Minnesota, S. I.4,5,12:i:-; S. Anatum, S. Cerro, S. Oranienburg, S. Braenderup, S. Give, S. Newport, S. IIIb 61:c:z35, S. 109:-:1.5, S. I.4.12:d:-, S. I.6.8:-:-. Multirresistência foi constatada em 43,33% (n=13) dos isolados, sendo um isolado obtido de animal sem diarreia e 12 isolados de animais com diarreia. Todas as técnicas de qPCR empregadas no estudo apresentaram maior número de amostras classificadas como positivas para Salmonella spp. comparadas ao cultivo bacteriológico de fezes. Adicionalmente, em todas as técnicas de qPCR houve maior número de animais detectados como positivos no grupo de animais com diarreia em relação aos animais sem diarreia. Os resultados confirmaram a utilidade do método qPCR sem a etapa de pré-enriquecimento em tetrationato, como um teste rápido para detecção de Salmonella spp. em animais portadores ou em animais com sinais clínicos de diarreia. O cultivo bacteriológico deve ser associado para a realização do teste de sensibilidade aos antimicrobianos e sorotipificação. O isolamento de Salmonella spp. em nove animais sem diarreia, confirma a importância dos animais portadores assintomáticos na epidemiologia da doença. A multirresistência observada evidencia a importância do uso racional de antimicrobianos em equinos e a importância da adoção de protocolos de biossegurança que sejam eficazes para controlar a disseminação de infecções entre animais e a transmissão zoonótica nas fazendas.

ABSTRACT: The present study investigated Salmonella spp. in the feces of 200 foals up to one year of age (100 with clinical signs of diarrhea and 100 without clinical signs of diarrhea). Bacteriological culture, serotyping, antimicrobial susceptibility, and real-time PCR (qPCR SYBR® Green or a TaqMan®) for detecting the invA gene (with and without a selective pre-enrichment step in tetrathionate broth) were performed. Bacterial culture revealed 15% (n=30) of positive animals (21 animals with diarrhea and nine without diarrhea). Among the 30 isolates, 13 different serovars were identified: S. Infantis, S. Minnesota, S. I.4,5,12:i:-; S. Anatum, S. Cerro, S. Oranienburg, S. Braenderup, S. Give, S. Newport, S. IIIb 61:c:z35, S. 109:-:1.5, S. I.4.12:d:-, S. I.6.8:-:-. Multidrug resistance was found in 43.33% (n=13) of the isolates, with one isolate obtained from animals without diarrhea and 12 isolates from animals with diarrhea. All qPCR techniques used in the study classified more samples as positive for Salmonella spp. than the bacterial culture of feces. In addition, all qPCR techniques detected more positive animals in the diarrhea group than in the diarrhea-free group. The results confirm the utility of the qPCR method without the pre-enrichment step in tetrathionate as a rapid test for Salmonella spp. in carrier animals. In animals with clinical signs of diarrhea, it can be combined with bacterial culture (antimicrobial susceptibility testing and serotyping). The isolation of Salmonella spp. in nine animals without diarrhea confirms the importance of asymptomatic carrier animals in the epidemiology of the disease. The multidrug resistance observed highlights the importance of rational antimicrobial use in horses and adopting biosecurity protocols that are efficacious in controlling the spread of infections between animals and zoonotic transmission in farms.
