Prevalence and characteristics of Shiga toxin-producing Escherichia coli isolated from retail raw meats in China.
Shiga toxin-producing Escherichia coli (STEC) causes diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome in humans. Most human infections are attributed to consumption of STEC-contaminated foodstuffs of animal origin. In this study, we evaluated the prevalence of STEC from retail raw meats collected from two geographical regions in China. The results revealed that 166 out of 853 sample...
متن کاملCharacterization of Shiga Toxin Subtypes and Virulence Genes in Porcine Shiga Toxin-Producing Escherichia coli
Similar to ruminants, swine have been shown to be a reservoir for Shiga toxin-producing Escherichia coli (STEC), and pork products have been linked with outbreaks associated with STEC O157 and O111:H-. STEC strains, isolated in a previous study from fecal samples of late-finisher pigs, belonged to a total of 56 serotypes, including O15:H27, O91:H14, and other serogroups previously associated wi...
متن کاملPathogenic and phylogenetic characteristics of non-O157 Shiga toxin-producing Escherichia coli isolates from retail meats in South Korea
Herein, we report the pathogenic and phylogenetic characteristics of seven Shiga toxin (Stx)-producing Escherichia coli (STEC) isolates from 434 retail meats collected in Korea during 2006 to 2012. The experimental analyses revealed that all isolates (i) were identified as non-O157 STEC, including O91:H14 (3 isolates), O121:H10 (2 isolates), O91:H21 (1 isolate), and O18:H20 (1 isolate), (ii) ca...
متن کاملIdentification of shiga toxin producing Escherichia coli O157:H7 in raw cow milk samples from dairy farms in Mashhad using multiplex PCR assay
In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...
متن کاملShiga-like-toxin-producing Escherichia coli in retail meats and cattle in Thailand.
Specific DNA probes were used to identify Shiga-like toxin I (SLT I)- and SLT II-producing Escherichia coli in vegetables, meats, cattle, and farm animals in Thailand. SLT-producing E. coli was isolated from 9% of market beef specimens, from 8 to 28% of fresh beef specimens at slaughterhouses, and from 11 to 84% of fecal specimens from cattle. Animals were frequently infected with several diffe...
