The objective of this study was to assess the effect environmental factors on microbiological quality water and oyster flesh (Crassostrea gasar) farmed in two Amazon estuaries Pará, Brazil. were located Nova Olinda community Augusto Corrêa (site 1) Lauro Sodré Curuçá 2). Physicochemical parameters (the rainfall, salinity, temperature pH) evaluated over a one-year period. A total six liters 720 samples from farms used analyze coliforms, Escherichia coli, coagulase-positive staphylococci,...
ABSTRACT: The present study identified virulence genes and pathological changes caused by Escherichia coli in chicken carcasses condemned for airsacculitis assessed if the histopathological examination polymerase chain reaction (PCR) were effective studies like this. Trachea, liver, lung collected from 30 chickens with suspected that has been inspection line. samples analyzed PCR to simultaneously identify two (iss tsh genes) testing. efficiently genotypically characterize E. isolates, where...
ABSTRACT The objective of the present study was to Standardize a Polymerase Chain Reaction (PCR) protocol for authentication bovine and buffalo milk, detect presence Salmonella spp. Listeria monocytogenes. For this, target DNA extracted, mixed, subjected PCR assay. Milk samples were defrauded experimentally contaminated with microorganisms assess detection at different times cultivation, bacterial titers, concentration genetic material. In addition, tested extracted directly from food,...
Resumo A pasteurização compreende uma etapa de suma importância para eliminação patógenos no leite e, a fim manter inocuidade do alimento, o controle desse processo é fundamental ponto vista da segurança alimentar. Assim, objetivo deste trabalho foi verificar aplicabilidade e sensibilidade dos procedimentos detecção fosfatase alcalina em bovino, bubalino caprino, experimentalmente pasteurizados fraudados com alíquotas cru. O pasteurizado acrescido cru nas seguintes percentagens: 0,1%; 0,25%;...
O objetivo deste estudo foi caracterizar o perfil do consumidor de produtos lácteos origem bubalina e bovina nos municípios Soure Salvaterra (Ilha Marajó-PA), quanto ao sociodemográfico, nível conhecimento sobre qualidade higiênico-sanitária as fraudes nesses produtos. Para coleta dos dados foram aplicados questionários em voluntários, todos escolhidos acaso. Os obtidos analisados forma descritiva posteriormente submetidos à análise correspondência múltipla (ACM). A resultou um total 403...
