In a study between January 1995 and July 1998 of 690 pet cats from 10 private animal hospitals in Sapporo, Hokkaido Prefecture; Sendai, Miyagi Prefecture; Joetsu, Niigata Prefecture; Fujisawa, Kanagawa Prefecture; Kyoto, Kyoto Prefecture; Sanda, Hyogo Prefecture and Mishima, Osaka Prefecture; Hikawa, Shimane Prefecture; Aira, Kagoshima Prefecture; Shimajiri, Okinawa Prefecture in Japan, Bartonella spp. were isolated from 7.2% (50/690) of all the cats examined. No Bartonella species were isolated from the cats in Sapporo or Sendai. The isolation rate varied from 2% in Joetsu and Sanda to 20% in Shimajiri. B. clarridgeiae was isolated from 2 of 50 cats in Kyoto, 3 of 50 in Mishima and 1 of 50 in Shimajiri, but not in cats from the other cities or counties. Though the cats of Joetsu, Fujisawa, Kyoto, Sanda, Aira and Shimajiri were infected with either B. henselae or B. clarridgeiae, 1 of 8 infected cats in Mishima was harbouring both Bartonella species. Type I of 16S rRNA gene was the predominant type among the isolates of B. henselae, but only one isolate derived from Shimajiri was found to be of type II. This is thought to be the first report on the prevalence of B. clarridgeiae and the 16S rRNA gene type of B. henselae among cats in Japan.
