First isolation of urease-positive thermophilic Campylobacter (UPTC) from crows (Corvus levaillantii) in Japan.

Two strains of urease-positive thermophilic Campylobacter (UPTC), designated YC98-1 and YC98-2, were identified by biochemical characterization after isolation from the intestinal contents of crows around Yokohama City, Japan, in 1998. The biochemical characteristics of these strains were identical to those of strains described previously. Pulsed-field gel electrophoresis (PFGE) after separate digestion with ApaI, SalI, and SmaI of the genomic DNA from the two strains indicated that respective PFGE profiles were distinctly different and distinguishable from each other. This is the first report of the isolation of UPTC from crows (Corvus levaillantii).
