intestinal carriage of yersinia pseudotuberculosis by wild birds and mammals in japan.fecal specimens were obtained from wild birds and mammals in the eastern part of shimane prefecture, japan, an area where serotype 1b, 2b, 3, and 4b strains of yersinia pseudotuberculosis were found to be prevalent in humans. each of 869 animals, including 259 wild birds and 610 wild mammals, was screened for yersiniae. a total of 37 strains of y. pseudotuberculosis were isolated from 34 (5.6%) mammals, including 23 raccoon dogs (nyctereutes procyonoides), eight deer (cervus nippon), two hares ( ...19912059038
[linear measurements of the bones of lepus brachyurus brachyurus temminck, pentalagus furnessi stone and oryctolagus cuniculus linnaeus (jw-nibs). i. on the cranium and ossa trunci (author's transl)].the ossa cranii and ossa trunci in lepus brachyurus brachyurus, pentalagus furnessi and oryctolagus cuniculus (strain : jw-nibs) were investigated morphologically and osteometrically. the number of coccygeal vertebrae is 10-12 in lepus, 10-11 in pentalagus and 15-17 in jw-nibs. the number of upper cheek teeth of pentalagus is six on one side. therefore, lyon's view that the number of upper cheek teeth of pentalagus is five may not be applicable to use as one of the discriminative characteristics ...19807193587
[linear measurements of the bones of lepus brachyurus brachyurus temminck, pentalagus furnessi stone and oryctolagus cuniculus linnaeus (jw-nibs). ii. on the ossa membri thoracici et pelvini (author's transl)].the bones of the thoracic and pelvic limbs of lepus brachyurus brachyurus, pentalagus furnessi and oryctolagus cuniculus (strain: jw-nibs) were investigated morphologically and osteometrically. the results obtained are summarized as follows. 1. the length of long bones in limbs is the largest in lepus except the distal phalanges, next in jw-nibs and the smallest in pentalagus. 2. the breadth of long bones in limbs except the distal phalanges is generally larger in pentalagus than in lepus and jw ...19817286065
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
pulmonary dirofilariasis in a japanese hare, lepus brachyurus angustidens.a case of pulmonary dirofilariasis in a japanese hare, lepus brachyurus angustidens captured in aomori prefecture, was first reported in japan. two dead worms recovered from the pulmonary artery and detected within an organized arterial thrombus in the lung, were identified as a male and a female young adult dirofilaria immitis, respectively. principal lesions in the lung were associated with pulmonary arterial degeneration and consisted of rugose and villous intimal fibrosis, endarteritis with ...19958593310
molecular phylogeny of japanese leporidae, the amami rabbit pentalagus furnessi, the japanese hare lepus brachyurus, and the mountain hare lepus timidus, inferred from mitochondrial dna sequences.we determined mitochondrial 12s ribosomal rna (rrna) and cytochrome b (cyt b) gene sequences in three leporid species of japan, the amami rabbit pentalagus furnessi from the ryukyu islands, the japanese hare lepus brachyurus from honshu, and a japanese form of the mountain hare lepus timidus ainu from hokkaido. we compared the sequences with those of other taxa of leporids available in databases. phylogenetic trees of the 12s rrna gene sequences indicated that the lineage of p. furnessi diversif ...200212087193
the influence of pleistocene refugia on the evolutionary history of the japanese hare, lepus brachyurus.we performed a phylogeographic analysis of the japanese hare, lepus brachyurus, using the mitochondrial cytochrome b gene (1140 bp). in total, 119 haplotypes were recovered from 197 samples isolated from 82 localities on three main islands of the japanese archipelago: honshu, sikoku, kyushu, sado island and the oki islands. results showed two distinct clades at a genetic distance of 3.5%, equivalent to an estimated 1.2 million years. the two clades, encompassing seven subclades, showed an appare ...201020822403
distribution of wild mammal assemblages along an urban-rural-forest landscape gradient in warm-temperate east asia.urbanization may alter mammal assemblages via habitat loss, food subsidies, and other factors related to human activities. the general distribution patterns of wild mammal assemblages along urban-rural-forest landscape gradients have not been studied, although many studies have focused on a single species or taxon, such as rodents. we quantitatively evaluated the effects of the urban-rural-forest gradient and spatial scale on the distributions of large and mid-sized mammals in the world's larges ...201323741495
pathological and microbiological studies of japanese hare (lepus brachyurus angustidens) naturally infected with francisella tularensis subsp. holarctica.an adult male hare (lepus brachyurus angustidens) was discovered in a moribund condition in the bush in the mountains of aomori prefecture in japan. upon gross inspection, many ticks were found on the neck and the external ear regions, and more than half the ticks contained blood in the intestine. the skin around the tick bite wounds was alopecic and mildly thickened. at necropsy, enlargement of the cervical lymph nodes and spleen were observed. histologically, acute necrotizing splenitis, lymph ...200920046031
ticks (acari: ixodidae) from medium-sized to large mammals in ehime prefecture, japan.ixodid ticks were collected from medium-sized to large mammals in ehime prefecture, shikoku, japan. ten species of ticks (amblyomma testudinarium, dermacentor taiwanensis, haemaphysalis flava, h. formosensis, h. hystricis, h. longicornis, h. megaspinosa, ixodes nipponensis, i. ovatus, and i. tanuki) were collected from a total of 29 mammals comprising 11 species. haemaphysalis hystricis, a possible vector of japanese spotted fever in ehime prefecture, was collected from canis lupus familiaris (d ...201323242932
