Studies on verotoxigenic Escherichia coli O157 in Swedish cattle From sampling to disease spread modelling
Verotoxigenic Escherichia coli O157:H7 (VTEC O157) is an important zoonotic pathogen capable of causing infections in humans, sometimes with severe symptoms such as hemorrhagic colitis and hemolytic uremic syndrome (HUS). Cattle are considered to be the main reservoir of the bacterium. In this thesis, sampling strategies to detect VTEC O157 in a cattle herd, risk factors for the introduction an...
متن کاملAdherence Patterns of Verotoxigenic Escherichia coli (VTEC) Non-O157 Strains Isolated from Faecal Samples in Iran
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...
متن کاملPreharvest control of Escherichia coli O157 in cattle.
Bovine manure is an important source of Escherichia coli O157 contamination of the environment and foods; therefore, effective interventions targeted at reducing the prevalence and magnitude of fecal E. coli O157 excretion by live cattle (preharvest) are desirable. Preharvest intervention methods can be grouped into 3 categories: 1) exposure reduction strategies, 2) exclusion strategies, and 3)...
متن کاملPCR detection of Escherichia coli O157:H7 directed from slaughtered cattle in Shiraz, Iran
Escheric hia coli O157:H7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . Detection of the low infectious dosage of bacterium requires a sensitive method. We developed polymerase chain reaction (PCR) assays to detect the gene Stx2 irrespective of the bacterial serotype. In this study, the detection limit of the PCR protocol in detecting Stx...
متن کاملThe Importance of Escherichia coli O157:H7 in Foodborn Infection
Enterohemorrhagic Escherichia coli O157: H7 is one of the most important causes of bloody diarrhea. This bacterium is able to make bloody diarrhea or Hemorrhagic Colitis (HC) through verotoxin or shigatoxin production, and in acute forms it may lead to Hemolytic Uremic Syndrome (HUS) or Thrombotic Thrombocytopenic Purpurea (TTP). Contamination with E. coli O157:H7 usually happens after consumpt...
