Caracterización de Escherichia coli productoras de toxina Shiga (STEC) recuperadas de canales bovinas uruguayas
Characterization of Shiga toxin-producing Escherichia coli (STEC) recovered from Uruguayan bovine carcasses

Escherichia coli productor de toxina Shiga (STEC) es un microorganismo zoonótico que coloniza el tracto intestinal de los animales y causa en el hombre diarrea de severidad variable y enfermedades graves, entre ellas, el síndrome urémico hemolítico post-entérico por STEC (SUH-STEC). El SUH-STEC inte...

Comparison of microbiological quality between illegal and inspected salami

Arq. Inst. Biol; 88 (), 2021
The consumption of meat and meat products can pose consumers into risk due to the presence of biological hazards that can cause foodborne diseases. Thus, this study aimed to compare the microbiological quality of illegal and inspected salami sold in the state of São Paulo, Brazil. For this purpose, 80 s...

Virulence genotyping and antimicrobial resistance profiles of Yersinia enterocolitica isolated from meat and meat products in Egypt

Braz. j. biol; 81 (2), 2021
Pathogenic Yersinia enterocolitica (Y. enterocolitica) is one of the food-borne entero-pathogen responsible for yersiniosis in humans. The purpose of this research was to survey the prevalence, virulence-associated genes, and antimicrobial resistance of Y. enterocolitica isolated from meat and meat produ...

Frequency of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) in non-clinical Enterococcus faecalis and Enterococcus faecium strains

Braz. j. biol; 79 (3), 2019
Abstract The fidelity of the genomes is defended by mechanism known as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems. Three Type II CRISPR systems (CRISPR1- cas, CRISPR2 and CRISPR3-cas) have been identified in enterococci isolates from clinical and environmental samples. Th...

Shigatoxigenic and atypical enteropathogenic Escherichia coli in fish for human consumption

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Shigatoxigenic and enteropathogenic Escherichia coli with virulence and multidrug resistance profile were isolated from Nile tilapia. This study finding is of great importance to public health because they help understand this pathogen epidemiology in fish and demonstrate how these animals can t...

El objetivo del presente estudio fue describir la presencia de Enterobacteriaceae en muestras de carne recolectadas en mercados tradicionales de Lima y establecer los niveles de resistencia a antimicrobianos y la presencia de betalactamasas de espectro extendido (BLEE) y AmpC en Esch...

Survival of Salmonella spp. in minced meat packaged under vacuum and modified atmosphere

Braz. j. microbiol; 49 (3), 2018
Abstract The effect of different modified atmosphere packaging regimes on the behavior of Salmonella spp. on minced meat was studied. Minced meat was experimentally contaminated with a Salmonella spp. cocktail (S. Enteritidis, S. Typhimurium, S. Infantis and S. Arizonae), packaged under vacuum or modifie...

Rapid detection of food-borne Salmonella contamination using IMBs-qPCR method based on pagC gene

Braz. j. microbiol; 49 (2), 2018
Abstract Detection of Salmonella is very important to minimize the food safety risk. In this study, the recombinant PagC protein and PagC antibody were prepared and coupled with immunomagnetic beads (IMBs) to capture Salmonella cells from pork and milk samples. And then the SYBR Green qualitative PCR was...
