Characterization of Shiga Toxigenic Escherichia coli Isolated from Foods [PDF]
Journal of Food Protection, 2007 The aim of this study was to characterize Shiga toxigenic Escherichia coli (STEC) by PCR using strains isolated from ham, beef, and cattle in Colombia. A total of 189 E. coli strains were tested for the presence of the uidA, stx1, and stx2 genes, and identification was confirmed by the automated PCR BAX system for E. coli O157:H7.

Effectiveness of Bacteriophages Against Biofilm-Forming Shiga-Toxigenic Escherichia coli on Leafy Greens and Cucumbers. [PDF]
Phage (New Rochelle), 2020 Background: Shiga-toxigenic Escherichia coli (STEC) have caused several produce-associated outbreaks, making it challenging to control these pathogens. Bacteriophages could serve as effective biocontrol.

Role of host xanthine oxidase in infection due to enteropathogenic and Shiga-toxigenicEscherichia coli [PDF]
Gut Microbes, 2013 Xanthine oxidase (XO) has been recognized as an important host defense enzyme for decades. In our recent study in Infection and Immunity, we found that enteropathogenic and Shiga-toxigenic E. coli (EPEC and STEC) were far more resistant to killing by the XO pathway than laboratory E. coli strains used in the past.

Reduced Virulence of an fliC Mutant of Shiga-Toxigenic Escherichia coli O113:H21 [PDF]
Infection and Immunity, 2006 ABSTRACT The contribution of flagellin to the virulence of the O113:H21 Shiga-toxigenic Escherichia coli (STEC) strain 98NK2 was investigated in the streptomycin-treated mouse model. Groups of mice were challenged with either the wild-type STEC or a fliC deletion derivative thereof.

Influence of Plant Species, Tissue Type, and Temperature on the Capacity of Shiga-Toxigenic Escherichia coli To Colonize, Grow, and Be Internalized by Plants. [PDF]
Appl Environ Microbiol, 2019 Fresh produce is an important vehicle for STEC transmission, and experimental evidence shows that STEC can colonize plants as secondary hosts, but differences in the capacity to colonize occur between different plant species and tissues.

Biological Activities of Uric Acid in Infection Due to Enteropathogenic and Shiga-Toxigenic Escherichia coli [PDF]
Infection and Immunity, 2016 ABSTRACT In previous work, we identified xanthine oxidase (XO) as an important enzyme in the interaction between the host and enteropathogenic Escherichia coli (EPEC) and Shiga-toxigenic E. coli (STEC).

Isolation and characterisation of Shiga toxigenic Escherichia coli strains from northern Palestine [PDF]
Journal of Medical Microbiology, 2002 Shiga toxigenic Escherichia coli (STEC) isolates from symptomatic and asymptomatic patients in northern Palestine in 1999 were screened for serotype O157 and characterised for virulence genes by multiplex PCR assay. Of the 176 STEC isolates, 124 (70.5%) were of serotype O157. All these isolates carried the gene for Shiga toxin type 1 (stx,) and 112 (90.

A scoping review on the prevalence of Shiga‐toxigenic Escherichia coli in wild animal species [PDF]
Zoonoses and Public Health, 2018 AbstractZoonotic pathogens constitute the major source (60.3%) of emerging infectious diseases. Previous studies have investigated the prevalence of Shiga‐toxigenic Escherichia coli (STEC) among wild animal species, but comprehensive data are needed to assess the role that these animals have in the transmission of STEC infections to the human ...
