| present status of trichinellosis in japan. | there have been three mass outbreaks of human trichinellosis in japan. the first was in 1974 in iwasaki, aomori prefecture, involving a group of hunters who ate raw meat of a black bear they had shot. of the 20 people who ate the bear meat raw, 15 showed clinical symptoms of trichinellosis. the second outbreak was experienced in sapporo, hokkaido, in 1980. the patients had eaten the raw meat of a brown bear served in a local restaurant. twelve people were diagnosed positive on the basis of clini ... | 1991 | 1822910 |
| 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 ... | 1993 | 8355353 |
| 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 |
| 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 ... | 2002 | 11949476 |
| 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 |
| epizootiological survey of trichinella spp. infection in carnivores, rodents and insectivores in hokkaido, japan. | in order to evaluate the present epidemiological situation of trichinella infection in wild animals in hokkaido, japan, red foxes (vulpes vulpes), raccoon dogs (nyctereutes procyonoides) , brown bears (ursus arctos) , martens (martes melampus), rodents and insectivores captured in hokkaido were examined for muscle larvae by the artificial digestion method from 2000 to 2006. foxes (44/319, 13.8%), raccoon dogs (6/77, 7.8%) and brown bears (4/126, 3.2%) were found to be infected with trichinella l ... | 2007 | 17405354 |
| genetic identification of mammalian carnivore species in the kushiro wetland, eastern hokkaido, japan, by analysis of fecal dna. | to identify mammalian carnivore species distributed in the kushiro wetland, eastern hokkaido, japan, we developed molecular-genetic methods for identification of the species from fecal samples collected from the field. species-specific primers and pcr programs were established for five native and six alien species of carnivores: martes zibellina, mustela nivalis, mustela erminea, vulpes vulpes, and nyctereutes procyonoides as native species, and neovison vison, martes melampus, mustela itatsi, c ... | 2008 | 18828658 |
| overwintering strategy of wild free-ranging and enclosure-housed japanese raccoon dogs (nyctereutes procyonoides albus). | the raccoon dog, nyctereutes procyonoides, is a canid with a passive overwintering strategy in northern europe. however, the behaviour and physiology of the japanese subspecies, n. p. albus, which has fewer chromosomes than the other subspecies, remain unknown. we measured body temperature, body composition and blood biochemistry of wild free-ranging and fasted enclosure-housed n. p. albus during boreal winter in hokkaido, japan. body temperature of n. p. albus decreased from 38 degrees c in aut ... | 2009 | 19101736 |
| detection of antibodies against japanese encephalitis virus in raccoons, raccoon dogs and wild boars in japan. | japanese encephalitis virus (jev) infects numerous animal species including humans, horses and pigs. in this study, antibodies against jev in feral raccoons (procyon lotor), wild boars (sus scrofa) and raccoon dogs (nyctereutes procyonoides) in japan were examined. the results showed that 40.7% (22 out of 54), 64.5% (40 out of 62), 69.1% (47 out of 68) and 0% (0 out of 20) of raccoons in hyogo, osaka, wakayama and hokkaido, respectively, had virus-neutralizing antibodies against jev. in addition ... | 2009 | 19721354 |
| multiplex pcr system for identifying the carnivore origins of faeces for an epidemiological study on echinococcus multilocularis in hokkaido, japan. | a multiplex pcr system was developed to identify the carnivore origins of faeces collected in hokkaido, japan, for epidemiological studies on echinococcus multilocularis. primers were designed against the d-loop region of mitochondrial dna. two separate primer mixtures (mix 1, specific forward primers to fox, raccoon dog and dog, and a universal reverse primer [prh]; and mix 2, specific forward primers to cat, raccoon and weasels and prh) were used so that the pcr products (160 bp, fox and cat; ... | 2009 | 19756739 |
| seasonal and diel activity patterns of eight sympatric mammals in northern japan revealed by an intensive camera-trap survey. | the activity patterns of mammals are generally categorized as nocturnal, diurnal, crepuscular (active at twilight), and cathemeral (active throughout the day). these patterns are highly variable across regions and seasons even within the same species. however, quantitative data is still lacking, particularly for sympatric species. we monitored the seasonal and diel activity patterns of terrestrial mammals in hokkaido, japan. through an intensive camera-trap survey a total of 13,279 capture event ... | 2016 | 27732611 |
