Survey on tick-borne pathogens in thoroughbred horses in the Hidaka district, Hokkaido, Japan.

A total of 87 Thoroughbred horses and 10 ixodid ticks from a ranch in Hidaka district, Hokkaido were tested for tick-borne diseases. Using the indirect fluorescent antibody (IFA) method, 3.4, 92.0 and 97.7% of the horses showed antibody titers of ≥ 80 against Anaplasma phagocytophilum, Rickettsia helvetica, and Borrelia garinii, respectively. This is the first report of infection with the 3 pat...

Serological and molecular survey of Rickettsial infection in cattle and sika deer in a pastureland in Hidaka District, Hokkaido, Japan.

Rickettsial infection of cattle and sika deer from a pastureland in Hidaka District, Hokkaido, Japan was examined by serological and molecular methods. Serum samples from 8 of 83 (9.6%) cattle reacted with Rickettsia helvetica antigens in an IFA test, with titers ranging from 1:160 to 1:640, while serum samples from 15 of 22 (68.2%) deer were positive for R. helvetica, with titers ranging from ...

Sterol composition in muscle and viscera of the marine bivalve Megangulus zyonoensis from coastal waters of Hokkaido, northern Japan.

Sterol composition in muscle and viscera tissues of the marine bivalve Megangulus zyonoensis was investigated. Among 13 different sterols identified by gas chromatography-mass spectrometry of their trimethylsilyl ether derivatives, cholesterol was the most abundant sterol, followed by 24-methylenecholesterol, in both muscle and viscera tissues. In this study, the proportion of brassicasterol, i...
