Abstract
ABSTRACT
Detection and analysis of
Babesia
species from ticks recovered from dogs in Japan were attempted by PCR and nucleotide sequence analysis based on the 18S rRNA gene, respectively. A total of 1,136 ticks were examined for
Babesia
DNA by 18S rRNA-based PCR and nucleotide sequencing. Partial sequences of
Babesia canis vogeli
DNA were detected from six ticks in Aomori, Nara, Hiroshima, Oita, and Okinawa Prefectures; and
Babesia gibsoni
Asia-1 DNA was also detected in four ticks in Osaka, Hiroshima, Miyazaki, and Okinawa Prefectures. Unique sequences of 1,678 bp were also obtained from
Ixodes ovatus
ticks in Akita and Fukui Prefectures. The sequences were similar to those of
Babesia odocoilei
(97.7%) and
Babesia divergens
(97.6%). This is the first report of the detection of DNA belonging to this group in Japan.
