Shiga toxin-producing O157 in piglets and food from backyard systems.

Piglets suffer from diarrhea caused by the Shiga toxin-producing (STEC) and can be carriers of the bacteria, with public health consequences in developing countries. The aim of the present study was to study the prevalence of STEC O157 in feces of 465 piglets and 54 food mixes from backyard systems, the antimicrobial susceptibility of STEC and the frequency of genes encoding extended-spectrum β-lactamases. The was isolated from 75.

Captive Green Iguana Carries Diarrheagenic Pathotypes.

The green iguana appears to be a carrier for bacteria causing gastrointestinal infections in humans. The presence of diarrheagenic (DEC) pathotypes, however, has not been studied in this reptile. The aim of the current work was to investigate the prevalence of DEC in the intestines of 240 captive green iguanas, their phylogenetic groups, and the antibiotic susceptibility profile.

Performance of culture media for the isolation and identification of Staphylococcus aureus from bovine mastitis.

Rapid isolation and identification of pathogens is a major goal of diagnostic microbiology. In order to isolate and identify Staphylococcus aureus, a number of authors have used a variety of selective and/or differential culture media. However, to date, there are no reports comparing the efficacy of selective and differential culture media for S.
