LONDON (Reuters Health) – Antibiotic-resistant Escherichia coli is commonly spread from animals to people in the Netherlands, according to a report in the June issue of the Journal of Antimicrobial Chemotherapy.
Dr. E. E. Stobberingh and colleagues from the University Hospital Maastricht in the Netherlands analyzed the prevalence of resistance in faecal E. coli in 47 turkeys and 50 broilers commonly given antibiotics and in 25 laying hens that were infrequently treated with antibiotics.
To examine the "possible dissemination of resistant E. coli or resistance genes from these poultry populations to humans," the researchers examined faecal samples from individuals who had contact with these animals. This included 47 turkey farmers, 51 broiler farmers, 25 laying-hen farmers, 47 turkey slaughterers and 46 broiler slaughterers.
The team also determined the MICS of antibiotics commonly used in poultry medicine and used pulsed-field gel electrophoresis (PFGE) to genotype ciprofloxacin-resistant isolates from all eight populations and from turkey meat.
Turkeys and broilers had a significantly higher prevalence of resistant E. coli than the laying-hen population. Turkey and broiler farmers and turkey and broiler slaughterers had a higher resistance to nearly all antibiotics than laying-hen farmers.
The investigators found that while multiresistant isolates were common in turkey and broiler farmers, they were absent in laying-hen farmers. In addition, turkeys, turkey farmers, turkey slaughterers, broilers, broiler farmers, and broiler slaughterers all had the same resistance patterns.
"The PFGE patterns of the isolates from the eight populations were quite heterogeneous, but E. coli with an identical PFGE pattern were isolated at two farms from a turkey and the farmer, and also from a broiler and a broiler farmer from different farms," Dr. Stobberingh and colleagues explain. "Moreover, three E. coli isolates from turkey meat were identical to faecal isolates from turkeys."
