Colistin and Biofilm‐Related Genes of Positive Escherichia coli O157:H7 in Cattle (Bos taurus) Carcasses Antibiotic Resistance Profiles, Biofilm and Molecular Characterisation of Isolates

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Antimicrobial resistance in various infectious agents poses a public health threat. Therefore, this study aimed to determine the antibiotic resistance profiles, biofilm formation abilities and molecular characterisation of colistin‐resistant Escherichia coli O157:H7 from cattle carcasses.

Adhesive threads of extraintestinal pathogenic Escherichia coli

Gut Pathogens, 2009
The ability to adhere to host surfaces is by far the most vital step in the successful colonization by microbial pathogens. Colonization begins with the attachment of the bacterium to receptors expressed by cells forming the lining of the mucosa.

Open-source genomic analysis of Shiga-toxin–producing E. coli O104:H4 [PDF]

, 2011
An outbreak caused by Shiga-toxin–producing Escherichia coli O104:H4 occurred in Germany in May and June of 2011, with more than 3000 persons infected. Here, we report a cluster of cases associated with a single family and describe an open-source genomic

Molecular Characterization of Virulent Genes and Antimicrobial Resistance Patterns of Escherichia coli Isolated From Calf Scours in Western Iran

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study in Western Iran analysed E. coli in diarrhoeic neonatal calves and identified 307 isolates from 350 faecal samples. The pathotypes included EHEC (36.59%), EPEC (20.42%), ETEC (14.46%), STEC (12.34%) and NTEC (11.48%), with four STEC O157:H7 isolates. Serotypes O103 and O15 were the most common.

Type 1 fimbriae-mediated collective protection against type 6 secretion system attacks

mBio
Bacterial competition may rely on secretion systems such as the type 6 secretion system (T6SS), which punctures and releases toxic molecules into neighboring cells.

Phosphorylated OmpR Is Required for Type 3 Fimbriae Expression in Klebsiella pneumoniae Under Hypertonic Conditions

Frontiers in Microbiology, 2018
OmpR/EnvZ is a two-component system that senses osmotic signals and controls downstream gene expression in many species of Enterobacteriaceae. However, the role of OmpR/EnvZ in Klebsiella pneumoniae remains unknown.
