Zoonosis Update Since Escherichia coli O157:H7 was first recognized in 1982 as a human pathogen, considerable progress has been made in elucidating principal vehicles of transmission. Cattle have been identified as a major source of E coli O157:H7 infection of humans, with as many as 1 in 4 animals at slaughter shedding the pathogen in feces during the summer months. 1 Case-control studies of s...

OBJECTIVE Ankaferd hemostat (Ankaferd Blood Stopper®, ABS)-induced pharmacological modulation of essential erythroid proteins can cause vital erythroid aggregation via acting on fibrinogen gamma. Topical endoscopic ABS application is effective in the controlling of gastrointestinal (GI) system hemorrhages and/or infected GI wounds. Escherichia coli O157:H7, the predominant serotype of enterohem...

AIMS The efficacy of antimicrobial ice was evaluated for the reduction of foodborne pathogens on the surface of fish. METHODS AND RESULTS Antimicrobial ice containing chlorine dioxide (ClO2) was utilized to control foodborne pathogens in laboratory media and on fish skin. Escherichia coli O157:H7, Salmonella serotype Typhimurium and Listeria monocytogenes strains were treated with antimicrobi...

Mastitis is a major problem in dairy farms and E. coli mastitis especially is a major disease in cows (1) because of the latter increasing incidence and severe symptoms (16). The concept of E. coli mastitis is that the organisms live in the environment and contaminate the teats probably as a result of fecal contamination (20). Shiga toxin-producing E. coli (STEC) isolates are an important group...

Atypical enteropathogenic Escherichia coli (aEPEC) is an important etiological agent of infantile diarrhea worldwide. Pathogenic aEPEC strains employ LEE-encoded proteins to subvert normal host cell functions, culminating in intestinal pathologic alterations termed attaching and effacing (A/E) lesions. In addition, some aEPEC strains harbor non-LEE effectors that may contribute to pathogenesis,...

BACKGROUND & OBJECTIVES Verotoxigenic Escherichia coli are important serotypes of enterohaemorrhagic E. coli (EHEC) subgroup that cause attaching and effacing lesions in enterocytes by producing verotoxins or shiga-like toxins resulting in haemorrhagic colitis (HC) and haemolytic uremic syndrome (HUS). The aim of this study was to detect these serotypes specially E. coli O157:H7 in stool sample...

Shiga toxin producing Escherichia coli (STEC) is a newly emerged pathogen has gained immense attention across the globe. It causes large scale epidemics and thousands of sporadic cases of diarrheal illness every year. STEC infections have been reported across the world and causes mild illness to severe bloody diarrhoea and even lifethreatening complications such as HUS in humans. The serotype O...

The adherence property of 70 verotoxigenicE. coli (VTEC) strains, not belonging to O157: H7 serotype (non-O157) was checked on HeLa cells adherence assay. These strains were isolated from patients with diarrhea and healthy individuals. The results obtained in this study revealed that localised adherence (LA) was manifested by 3 strains of which two belonged to serogroups O111, O127 and the thir...

Shiga toxin 2 (Stx2) from the foodborne pathogen Escherichia coli O157:H7 is encoded on a temperate bacteriophage. Toxin-encoding phages from C600::933W and from six clinical E. coli O157:H7 isolates were characterized for PCR polymorphisms, phage morphology, toxin production, and lytic and lysogenic infection profiles on O157 and non-O157 serotype E. coli. The phages were found to be highly va...

Enterohemorrhagic Escherichia coli (EHEC) O157:H7 causes bloody diarrhea and hemolytic-uremic syndrome (HUS) and is the most prevalent E. coli serotype associated with food-borne illness worldwide. This pathogen is transmitted via the fecal-oral route and has a low infectious dose that has been estimated to be between 10 and 100 cells. We and others have previously identified three prophage-enc...
