| epidemiology, histopathology, and muscle distribution of trichinella t9 in feral raccoons (procyon lotor) and wildlife of japan. | the prevalences of trichinella t9 in trapped raccoons (procyon lotor) and several other potential mammalian reservoirs in hokkaido, wakayama, and nagasaki prefectures were investigated. muscle samples were collected from 2003 to 2006 from 1,080 raccoons, 113 raccoon dogs including 2 species (nyctereutes procyonoides albus and n. p. viverrinus), 41 wild boars (sus scrofa leucomystax), 14 martens (martes melampus), 10 badgers (meles meles), 5 siberian weasels (martes sibirica coreana), 7 mink (mus ... | 2007 | 17310398 |
| trichinella nativa and trichinella t9 in the hokkaido island, japan. | trichinella sp. muscle larvae were isolated from the thigh muscle of two red foxes (vulpes vulpes) captured in sapporo and otofuke, hokkaido, japan, in 2003. multiplex pcr designed for genotyping the genus trichinella revealed that the sapporo isolate showed a specific pattern to t. britovi complex (t. britovi, trichinella t8 and trichinella t9) and the otofuke isolate showed that to t. nativa. nucleotide sequences of a part of the mitochondrial cytochrome oxidase subunit i (coi) gene and intern ... | 2006 | 17049300 |

| 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 ... | 2001 | 11438434 |
| efficacy of anthelmintic baiting of foxes against echinococcus multilocularis in northern japan. | field application of anthelmintic baits against echinococcus multilocularis in red foxes (vulpes vulpes) was conducted on nemuro peninsula at the eastern edge of hokkaido, japan. the total study area was 412 km(2), of which 135 km(2) were used for bait distribution. commercial baits containing 50mg praziquantel were distributed by car along roads outside towns and villages in a density of 15/km(2). additional baits were distributed around fox breeding dens. baiting was done from november 1999 to ... | 2013 | 24001877 |
