Assesses antibiotic resistance in E. coli strains from livestock, suggesting a need for better controls.

The central aim is to evaluate antibiotic resistance levels in E. coli from livestock facilities and assess associated risks.
Isolated 202 E. coli strains from fresh milk, raw meat, and other livestock sources.
Tested susceptibility against 17 antibiotics using Mueller-Hinton agar.
Measured inhibition zones after incubation at 35 ± 2 °C for 18–24 hours.
High resistance to ampicillin (65.5%) and third-generation cephalosporins (up to 40%).
Moderate resistance to fluoroquinolones, specifically ciprofloxacin (24.3%).
Maximum susceptibility was found for carbapenems (97.5%) and colistin (94.0%).
Resistance varied significantly based on sample type, with swabs and dairy showing highest rates.

Yelshibayev et al. (2026) studied this question.
