Description
Wiwiek Tyasningsih and a large Indonesian team hunt, in a 2026 study, for resistance genes in bacteria carried by market quails in Surabaya. E. coli from poultry serves as a sentinel for drug resistance. Strains producing ESBL enzymes, especially the CTX-M family, threaten both animal and human treatment. The team swabbed 100 quails across five markets between November and December 2024. They identified the bacteria, profiled drug response, and screened resistant isolates for the CTX-M gene.
Nearly every sample, 98 percent, grew E. coli. Resistance was common to ciprofloxacin at 50 percent and tetracycline at a third of isolates. Four isolates resisted multiple drug classes. Among twenty isolates resistant to aztreonam, eight carried CTX-M genes. Patterns differed between markets, pointing to differences in drug use or exposure. The authors warn that markets can act as reservoirs of resistance. They call for a closer watch and hygiene along the quail supply chain.
