hepatozoon infection in a wild fox (vulpes vulpes schrencki kishida) in japan. 19827098235
lyme disease spirochetes in a wild fox (vulpes vulpes schrencki) and in ticks.lyme disease spirochetes were demonstrated in a wild female fox (vulpes vulpes schrencki) and in ixodes persulcatus ticks collected from the fox on sapporo, hokkaido, japan. spirochetes were detected in i. persulcatus, as well as skin lesions, brain, heart, kidney, and liver of the fox. five of seven isolates reacted with a monoclonal antibody against borrelia afzelii specific osp b. deoxyribonucleic acid (dna) relatedness of a brain isolate was 89% to b. afzelii, and ranged from 50 to 67% to th ...19947933292
coproantigen detection in a survey of echinococcus multilocularis infection among red foxes, vulpes vulpes schrencki, in hokkaido, japan.detection of echinococcus coproantigen using sandwich enzyme-linked immunosorbent assay (selisa) was performed on fecal samples of red foxes in hokkaido, japan. fecal samples were collected around fox dens in 1990 and 1992. the antibodies used for selisa recognize heat-resistant antigens, thus all fecal samples were heated to render it safe for handling before examination. detection of taeniid egg in fox feces collected was considered as an indication of e. multilocularis infection. in fecal sam ...19989637302
prevalence and intensity of echinococcus multilocularis in red foxes (vulpes vulpes schrencki) and raccoon dogs (nyctereutes procyonoides albus) in otaru city, hokkaido, japan.a survey was done in an attempt to investigate the epidemiological status of echinococcus multilocularis in red foxes and raccoon dogs in otaru city from june to september 1999. sixty-seven red foxes (vulpes vulpes schrencki) and 13 raccoon dogs (nyctereutes procyonoides albus) were captured, and postmortem examinations were conducted with them. thirty-eight red foxes (56.7%) and 3 raccoon dogs (23.1%) were found to be infected with e. multilocularis. the total biomass of e. multilocularis in al ...200211949476
characterization and application of newly developed polymorphic microsatellite markers in the ezo red fox (vulpes vulpes schrencki).the ezo red fox (vulpes vulpes schrencki), a subspecies endemic to hokkaido island, japan, is a known host species for the tapeworm echinococcus multilocularis. to develop tools for molecular ecological studies, we isolated 28 microsatellite regions from the genome of ezo red fox, and developed 18 polymorphic microsatellite markers. these markers were characterized using 7 individuals and 22 fecal samples of the ezo red fox. the number of alleles for these markers ranged from 1 to 7, and the obs ...201628002597
adenosquamous carcinoma with cilium formation, mucin production and keratinization in the nasal cavity of a red fox (vulpes vulpes schrencki).a diagnosis of adenosquamous carcinoma was made in an 11-year-old red fox. the animal showed emaciation and purulent nasal discharge. necropsy revealed diffuse thickening of the nasal mucosa and tumours on the soft palate, and there was an oronasal fistula contiguous with the tumours. the nasal and oral lesions were composed of adenocarcinomatous cells and squamous cells, the latter predominating in the oral lesions. the marrow of the palatine bone also contained neoplastic tissue, which consist ...200717645890
first report of trichinella nativa in red foxes (vulpes vulpes schrencki) from otaru city, hokkaido, japan.forty-three red foxes (vulpes vulpes schrencki) and nine raccoon dogs (nyctereutes procyonoides viverrinus) were captured in otaru city, hokkaido, japan and examined by muscle digestion for the presence of trichinella sp. larvae. of the foxes, five (11.6%) were positive for larvae of trichinella nativa while none of the raccoon dogs were found to be positive. this finding suggests that the red foxes are important reservoir hosts of sylvatic trichinellosis in otaru, hokkaido. this is the first re ...200111438434
