The presence of fungi and contaminating bacteria in ripened cheeses is a major concern for the dairy industry worldwide. Therefore, objective this study was to evaluate antimicrobial activity oregano essential oil (Origanum vulgare L.) (OEO) against (Escherichia coli Staphylococcus aureus) filamentous on during ripening. For purpose, Minas were produced artificially contaminated with strains enteropathogenic E. coli, multidrug-resistant S. aureus, Aspergillus flavus, Fusarium oxysporum,...
Cow raw milk cheese is widely eaten in Brazil. These products may be contaminated with pathogenic bacteria. In this work, we investigated the presence of Escherichia coli from different States From 147 "Minas" samples, 28 cheeses were positive for E. coli. Among 39 isolates cheeses, one was eae and negative bpfA efa1/lifA using PCR, so classified as atypical Enteropathogenic (aEPEC). Two other extraintestinal (ExPEC) genes. The aEPEC isolate belongs to serogroup O127 A phylogenetic group,...
Shiga toxin-producing Escherichia coli (STEC) colonize the gastrointestinal tract of animals; however, STEC may also cause severe diarrheal diseases. Food-producing animals have been acting as reservoirs and disseminators multidrug-resistant (MDR) bacteria antimicrobial resistance genes (ARGs); there are few studies characterizing molecularly bacterial isolates from sheep. Therefore, this study aimed to characterize E. obtained feces sheep in a Brazilian farmhouse. A total 14 MDR were 100...
Parmesan-type cheeses are the most consumed special in Brazil. It is generally sold retail shops, either grated or wedge-shaped pieces, and its quality varies considerably, which reflected directly price. There lack of processing standardization and, since ripening period fundamental for this hard, semi-fat cooked cheese, stage seems to be thin line between low high products. important note that Italian Parmegiano Reggiano matured a twelve months, as well rival Grana Padano, long causes...
The aim of this study was to detect 2 important toxin genes from diarrheagenic Escherichia coli (DEC) in bovine milk using a new multiplex PCR. To standardize the PCR, stx2 and elt were investigated for detection Shiga toxin-producing (STEC) enterotoxigenic E. (ETEC), respectively. DNA template prepared with thermal procedure (boiling) commercial kit. Samples consisted UHT pasteurized milk, both skimmed, STEC ETEC tested concentrations between 101 109 cfu/mL. With procedure, PCR system...
Cheese consumption has shown an important increase throughout the Brazilian territory, being second most imported product since 2015. Among different types of cheese, minas frescal represents one popular, due to its simple processing, low cost and high yield. However, perishability requires refrigeration relatively fast consumption, thus representing limiting factor in commercialization. Aspects such as having a moisture content, not undergoing maturation, containing no preservatives,...
