Salmonella isolated from the feces of migrating cranes at the Izumi Plain (2002-2008): serotype, antibiotic sensitivity and PFGE type.

From November 2002 to February 2008, 2,251 crane feces were collected at the Izumi Plain in Kagoshima Prefecture. Salmonella enterica was isolated from 359 feces (15.9%), of which 332 (92.5%) were Salmonella Typhimurium (ST), 9 were S. Hvittingfoss/II, 4 were S. Abaetetuba, 3 were S. Enteritidis, 2 were S. Konstanz, 1 was S. Pakistan and 8 were untyped isolates, respectively. Against 12 antimicrobial agents, no resistant strains were found in 154 isolates examined, but one was found to be resistant to ampicillin. By pulsed-field gel electrophoresis (PFGE), all but one of the 68 ST isolates tested showed indistinguishable banding patterns; one had a different pattern. The results suggest that ST strains from the same origin would spread in crane flocks during their stay at Izumi Plain every winter.
