Environmental sampling for evaluating verotoxigenic Escherichia coli O157

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...

Adherence 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...

Agricultural, socioeconomic and environmental variables as risks for human verotoxigenic Escherichia coli (VTEC) infection in Finland

BACKGROUND Verotoxigenic E. coli (VTEC) is the cause of severe gastrointestinal infection especially among infants. Between 10 and 20 cases are reported annually to the National Infectious Disease Register (NIDR) in Finland. The aim of this study was to identify explanatory variables for VTEC infections reported to the NIDR in Finland between 1997 and 2006. We applied a hurdle model, applicable...
