Title: Seroepidemiological study of canine ehrlichial infections in Yamaguchi prefecture and surrounding areas of Japan
Abstract: Randomly selected serum samples from 150 dogs from Yamaguchi and neighbouring prefectures were subjected to the indirect immunofluorescent assay to detect antibodies against Ehrlichia canis, Ehrlichia chaffeensis, Ehrlichia muris and Ehrlichia from Ixodes ovatus. A total of 30 out of the 150 serum samples reacted with at least one of the antigens at a titer of 1:20 or more. Considerable cross-reactivity was seen and most samples reacted with at least two different antigens. Fifteen (10.0%) dogs had higher titers to E. canis than any of the other antigens. Four (2.7%) dogs had higher titers to Ehrlichia from Ixodes ovatus and one (0.6%) dog had higher titers to E. muris compared to the other antigens. The findings suggest that these five dogs may be infected with the domestic Ehrlichia of Japan. The remaining ten dogs had similar high titers to two or more of the antigens. This is the first serological evidence obtained of canine infection with the domestic Ehrlichia of Japan.
