A total of 328 cloacal swabs and 163 footpads of wild birds were investigated for the detection of salmonellae. All 19 isolates from cloacal swabs were serotyped as Salmonella Typhimurium and were susceptible to all five conventional antimicrobial agents (ampicillin, chloramphenicol, streptomycin, oxytetracycline and nalidixic acid) tested. In contrast, 15 salmonellae isolated from footpads included S. Muenhen, S. Virchow, S. Bareily and S. Bovismobificans, including S. Typhimurium, and these non Salmonella Typhimurium isolates showed multiple drug resistance.
