Managemental influences on the selective proliferation of two strains of haemolytic Escherichia coli in weaned pigs [PDF]

, 1988
In an experimental study on a piggery it was found that haemolytic Escherichia coli of O-serotypes 138 or 139 proliferated in the intestinal tracts of pigs following weaning, with E.

Always one step ahead: How pathogenic bacteria use the type III secretion system to manipulate the intestinal mucosal immune system [PDF]

, 2011
The intestinal immune system and the epithelium are the first line of defense in the gut. Constantly exposed to microorganisms from the environment, the gut has complex defense mechanisms to prevent infections, as well as regulatory pathways to tolerate ...

Multiplex PCR to Diagnose Gastrointestinal Infections: Key Limitations in Interpretation

United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.
ABSTRACT Multiplex polymerase chain reaction (PCR) panels are increasingly used for the evaluation of acute diarrhea, providing rapid and sensitive detection of a broad range of enteric pathogens. However, their widespread adoption has created important interpretive challenges for clinicians.

Atypical Enteropathogenic Escherichia coli

, 2016
The atypical enteropathogenic Escherichia coli (EPEC), a subgroup of EPEC, has the ability to cause histopathologic attaching and effacing lesions in eukaryotic cells, but lacks the virulence-associated EPEC adherence factor plasmid.

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Pathogenic Foodborne Bacteria in the Game Meat of Hunted Large Ungulates—A Systematic Review and Meta‐Analysis

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Zoonotic bacterial pathogens are a major concern for food safety, yet information regarding their occurrence in game meat remains fragmented. This systematic review synthesizes available data on Salmonella spp., Shiga toxin‐producing Escherichia coli (STEC), Listeria spp., Yersinia spp., and Campylobacter spp.
