serological evidence of coxiella burnetii infection in wild animals in japan.one hundred and thirty-four (26%) of 511 sera from 11 wild animal species in eight prefectures in japan had antibody titers to coxiella burnetii by the enzyme-linked immunosorbent assay. high prevalences were observed in japanese black bears (ursus thibetanus) (78%), hokkaido deer (cervus nippon yesoensis) (69%), japanese hares (lepus brachyurus) (63%), japanese deer (cervus nippon centralis) (56%), and to some extent in japanese monkeys (macaca fuscata) (28%). a low prevalence (13%) was observe ...19938355353
seasonal variations in the presence of antibodies against coxiella burnetii in dairy cattle in hokkaido, japan.the prevalence and seasonal variations of infection by coxiella burnetti in cattle were investigated seroepidemiologically on a farm in hokkaido, japan, by an immunofluorescent antibody test. a total of 364 serum samples from 28 cows were collected from august 1993 to october 1995 in two barns on the farm. it was found that the number of antibody-positive cows and their antibody titers were significantly elevated in winter and decreased in summer. in addition, antibodies were detectable in seroc ...19979087948
detection of coxiella burnetii from dust in a barn housing dairy cattle.we attempted to detect coxiella burnetii in dust samples collected from a barn housing dairy cattle by the polymerase chain reaction (pcr) method. ten dust samples (five from ventilation fans and five from crossbeams) were collected from two areas in a barn on a farm near sapporo, hokkaido. c. burnetii was detected in 5 of the 10 dust samples. it was believed that aerial contamination by c. burnetii occurred in the barn.19989525780
serological survey of five zoonoses, scrub typhus, japanese spotted fever, tularemia, lyme disease, and q fever, in feral raccoons (procyon lotor) in japan.we investigated the seroprevalence of five tick- or mite-borne zoonoses, scrub typhus (orientia tsutsugamushi), japanese spotted fever (rickettsia japonica), tularemia (francisella tularensis), lyme disease (borrelia afzelii and borrelia garinii), and q fever (coxiella burnetii), in feral raccoons (procyon lotor) captured in hokkaido and kanagawa prefectures in japan. of the 559 raccoons captured in hokkaido, 8 (1.4%), 3 (0.5%), 1 (0.2%), and 1 (0.2%) carried antibodies against o. tsutsugamushi ...201120553108
serological screening of coxiella burnetii (q fever) and brucella spp. in sheep flocks in the northern prefectures of japan in 2007.ovine sera collected from the northern prefectures of hokkaido, iwate and aomori in japan, were examined for the presence of antibodies against coxiella burnetii (q fever) using the complement fixation test and, against brucella spp., using both the rapid serum agglutination test and the complement fixation test. none of the sera tested were serologically positive to brucella spp. a total of 21 animals (8.64%) out of 243 samples tested were seropositive to the c. burnetii antigen. levels of infe ...201223277117
epidemiological survey for toxoplasma gondii, chlamydia psittaci var. ovis, mycobacterium paratuberculosis, coxiella burnetii, brucella spp., leptospirosis and orf virus among sheep from northern districts of japan.a serological survey was carried out in the northern prefectures of hokkaido, iwate and aomori in japan, for the presence of antibodies against toxoplasma gondii, chlamydiapsittaci var. ovis, mycobacterium paratuberculosis, coxiella burnetii, brucella spp., leptospirosis and orf virus (orfv). out of 267 samples tested, highest overall prevalence (28.78%) was found for t. gondii. the 12.59% of tested sheep were positive for c. psittaci var. ovis. a total of 8.67% were found to be seropositive for ...201323318575
