Biological Activities of Uric Acid in Infection Due to Enteropathogenic and Shiga-Toxigenic Escherichia coli. [PDF]
Infect Immun, 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).

Role of host xanthine oxidase in infection due to enteropathogenic and Shiga-toxigenic Escherichia coli. [PDF]
Infect Immun, 2013 ABSTRACT Xanthine oxidase (XO), also known as xanthine oxidoreductase, has long been considered an important host defense molecule in the intestine and in breastfed infants. Here, we present evidence that XO is released from and active in intestinal tissues and fluids in response to infection with enteropathogenic ...

Biomédica: revista del Instituto Nacional de Salud, 2023 Introduction. Shiga toxin-producing Escherichia coli (STEC) is a foodborne pathogen associated with clinical cases of diarrhea in humans. Its main virulence factors are the Shiga toxins (Stx1 and Stx2).

Fatal hemorrhage induced by subtilase cytotoxin from Shiga-toxigenic Escherichia coli [PDF]
Microbial Pathogenesis, 2011 Subtilase cytotoxin (SubAB) is an AB(5) type toxin produced by a subset of Shiga-toxigenic Escherichia coli. The A subunit is a subtilase-like serine protease and cleaves an endoplasmic reticulum chaperone BiP. The B subunit binds to a receptor on the cell surface. Although SubAB is lethal for mice, the cause of death is not clear.

Surveillance of Shiga toxigenic Escherichia coli in Australia
Communicable Diseases Intelligence, 2005 All Australian States and Territories have low rates (= 0.32 cases per 100,000 population) of notification for Shiga toxin-producing Escherichia coli (STEC), except for South Australia where the rates are tenfold higher at 2.58 cases per 100,000 population.

Prevalence of Escherichia coli O157 isolated from marketed raw cow milk in Kwara State, Nigeria
Scientific African, 2023 Escherichia coli (E. coli) is a common cause of poor milk microbial quality, often resulting from unhygienic milk handling. Here, a cross-sectional study was performed to determine the prevalence and antibiotic susceptibility profile of E.

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.

Molecular characterization of Escherichia coli recovered from traditional milk products in Kashan, Iran [PDF]
Veterinary World, 2017 Aim: Shiga toxigenic Escherichia coli (STEC) strains as emerging groups of foodborne pathogens are responsible for most foodborne illnesses. The aim of this study was to determine the antibiotic resistance pattern in STEC isolated from traditional milk ...

Emerging Infectious Diseases, 2021 We describe the consequences of 2 major changes in notification criteria for Shiga toxin–producing Escherichia coli surveillance in the Netherlands. The change to reporting acute, more severe infections appears to be a good compromise between workload ...

Characterization of Shiga Toxigenic Escherichia coli Isolated from Foods
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.
