Study reveals antimicrobial resistance and virulence genes in E. coli from cattle, highlighting risks of horizontal gene transfer across regions.

To investigate antimicrobial resistance, virulence, and plasmid profiles of E. coli from diarrheic cattle in China.
Characterized 91 E. coli isolates from four provinces using antimicrobial susceptibility testing and whole-genome sequencing.
Identified antibiotic resistance genes (ARGs) and virulence genes in the isolates.
Performed plasmid profiling to detect replicon types and analyze correlations with ARGs.
Conducted phylogenetic analysis to identify sequence types (STs) and serotypes.
Common resistance observed to ampicillin (49.5%), cefotaxime (37.4%), and tetracycline (36.3%).
Identified 21 multidrug-resistant strains, mainly from Ningxia and Shanxi.
Detected 53 distinct ARGs and 196 virulence genes, with key adherence and secretion systems prevalent.
Established a strong correlation between plasmids and ARGs, indicating high risk for horizontal gene transfer.
Identified 45 STs and 59 serotypes, revealing geographic dissemination patterns.

Wang et al. (2025) studied this question.
