| Com o objetivo de analisar as características físico-químicas do leite UAT durante sua industrialização e de comparar os resultados com a legislação vigente, foram analisadas 150 amostras, colhidas em seis etapas, em diferentes fases do processamento, sendo 60 de leite cru, 60 de leite pasteurizado e 30 de leite UAT. As amostras foram submetidas à determinação de acidez titulável, densidade, teor de gordura, extrato seco total (EST) e desengordurado (ESD), ponto crioscópico, pH, redutase, estabilidade ao álcool 68% e à pesquisa das enzimas peroxidase e fosfatase alcalina. Os resultados indicaram que os valores médios do extrato seco total e do extrato desengordurado, bem como do índice crioscópico apresentaram-se, em algumas colheitas, inferiores aos... |

| ABSTRACT: Brazilian poultry industry generates large amounts of organic waste, such as chicken litter, which is often used in agriculture. Among the bacteria present in organic fertilizer are members of the Enterobacteriaceae family, such as Escherichia coli. The aim of this study was to analyze the profile of virulence factors and antimicrobial resistance of E. coli isolates from avian organic fertilizer. A total of 47 E. coli strains were tested through Polymerase chain reaction to detect virulence genes (hlyF, iss, ompT, iutA and iroN). Fourteen antimicrobials were used to test antimicrobial susceptibility in the strains. Genes characteristic of Avian Pathogenic E. coli (APEC) were reported among the strains, with the hlyF, iss and ompT genes being the... |

| ABSTRACT In this experiment, the beneficial effects of mannan-oligosaccharide (MOS) on immunology and intestinal microbiology of Nile tilapia juveniles was demonstrated. Prior to this, three levels of MOS in Nile tilapia diets (1, 8, and 15 g.kg−1) were tested, and hematological parameters, serum lysozyme, and intestinal microbiology were analyzed. The fish blood was sampled at day zero (basal sample) and after 45 days of trial, and the intestinal microbiota was evaluated at the end of the experiment. After 45 days of trial, fish fed 8 and 15 g.kg−1 of MOS presented an increase in both aerobic and lactic acid bacteria numbers in their guts. The MOS feeding also increased the counts of total leukocytes, monocytes, and lymphocytes of fish, but a decrease in... |
