| [anti-toxoplasma antibody levels in the main-land raccoon dog, nyctereutes procyonoides viverrinus, in southeastern kanagawa prefecture]. | naturally-occurring toxoplasma infection has been observed for years in various kinds of wild animals. however, the infection situation has not been well characterized due to a lack of research. in present study, latex fixation tests were conducted for 109 main-land raccoon dogs (67 males and 42 females) all of which were kept in kanazawa zoo in yokohama city, kanagawa prefecture between 1991-1994 to measure levels of toxoplasma antibodies. the test results indicated 20 positive samples out of t ... | 1996 | 8952267 |
| [incidence of antibodies in raccoon dogs and deer inhabiting suburban areas]. | we evaluated the incidence of antibodies against canine distemper (cd) virus, canine parvovirus, toxoplasma gondii (t. gondii), aujeszky's disease virus, porcine reproductive and respiratory syndrome virus, rickettsia tsutsugamushi, rickettsia japonica, and coxiella burnetii in 30 raccoon dogs and 5 deer captured in suburban areas in kanagawa prefecture. among the raccoon dogs, anti-t. gondii antibody was detected in 1 animal (3.3%) and anti-cd virus antibody in 9 (30.0%). however, antibodies ag ... | 1998 | 9621559 |
| mange caused by sarcoptes scabiei (acari: sarcoptidae) in wild raccoon dogs, nyctereutes procyonoides, in kanagawa prefecture, japan. | parasitological and histopathological examinations were performed in 25 raccoon dogs (nyctereutes procyonoides) obtained in kanagawa prefecture, japan, all of which were found to be heavily infected with sarcoptes scabiei. the mites detected on these raccoon dogs were morphologically indistinguishable from the human species, and no demodex mites were detected. histopathological examinations showed prominent hyperkeratosis and acanthosis with eczema, and numerous burrows containing mites were obs ... | 2001 | 11346184 |
| prevalence of dirofilarial infection in raccoon dogs in japan. | the raccoon dog (nyctereutes procyonoides viverrinus) is known to acquire canine heartworm (dirofilaria immitis) infection. we surveyed the prevalence of heartworm infection in free-ranging raccoon dogs in the nishi-tama (tokyo) and kanagawa areas of japan. a total of 75 raccoon dog carcasses, including 29 animals from the nishi-tama area and 46 from the kanagawa area, were necropsied between 1992 and 1993. eight out of 75 raccoon dogs were found to be infected (overall 10.7%). the prevalence of ... | 2000 | 11426580 |
| notoedric mange in two free-ranging north american racoons (procyon lotor) in japan. | mange was diagnosed in two north american racoons (procyon lotor) at kamakura city in kanagawa prefecture, japan. the mites were identified morphologically as notoedres cati. mite infestation affected the skin over the extremities and tail, and was characterized by moderate alopecia and erythematous dermatosis. histopathologically, the affected skin showed marked epidermal hyperplasia and mites located within the parakeratotic stratum corneum. a slight dermal inflammatory response consisting pri ... | 2002 | 11972895 |
| persistent organochlorines in raccoon dogs (nyctereutes procyonoides) from japan: hepatic sequestration of oxychlordane. | the present study determined the accumulation features of persistent organochlorines (ocs) such as polychlorinated biphenyls (pcbs), dichlorodiphenyltrichloroethane and its metabolites (ddts), hexachlorocyclohexane isomers (hchs), hexachlorobenzene (hcb), and chlordane compounds (chls) in wild raccoon dogs (rds; nyctereutes procyonoides) collected from kanagawa prefecture in japan during 2001. in livers of rds, chls were remarkably dominant (20 times higher than pcbs) followed by pcbs>ddts>hchs> ... | 2007 | 16839592 |
| serological survey of ehrlichia and anaplasma infection of feral raccoons (procyon lotor) in kanagawa prefecture, japan. | numbers of feral raccoon; the possible reservoir animal of ehrlichia and anaplasma, are increasing in japan. thus serological methods were utilized to examine ehrlichia and anaplasma infection in raccoons from kanagawa prefecture, japan. by using an indirect immunofluorescence assay, among 187 feral raccoons examined, 1 (0.5%) serologically reacted with ehrlichia canis, 3 (1.6%) with ehrlichia chaffeensis and 1 (0.5%) with anaplasma phagocytophilum with the titers of 1:40 or more. although scree ... | 2007 | 17157441 |
| isolation and characterization of leptospira spp. from raccoons in japan. | we investigated whether raccoons (procyon lotor) carried leptospires in their kidneys in japan. leptospira was isolated from 2 of 71 raccoons captured in kanagawa prefecture and 1 of 53 raccoons at a zoological park in nagasaki prefecture. anti-leptospira antibodies were detected in 16 of 124 raccoons (12.9%) in kanagawa and 33 of 53 raccoons (62.3%) in nagasaki, respectively. the partial nucleotide sequences of their flab genes suggested that the isolates belonged to l. interrogans. the serovar ... | 2009 | 19420844 |
| 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 ... | 2011 | 20553108 |
| prevalence of dirofilaria immitis infection in living raccoon dogs assessed by hematological examination. | the prevalence of dirofilaria immitis in free-ranging raccoon dogs (nyctereutes procyonoides viverrinus) was examined in the southeast region of kanagawa prefecture, japan, using a rapid immunomigration (rim) test kit. between april 2007 and march 2010, we examined 108 raccoon dogs rescued and housed by the kanazawa zoological garden. d. immitis infection was found in 8 (7.4%) raccoon dogs. this is the first report to reveal the prevalence of d. immitis infection in living raccoon dogs. the prev ... | 2011 | 21293077 |
| hematology and serum biochemistry in debilitated, free-ranging raccoon dogs (nyctereutes procyonoides) infested with sarcoptic mange. | frequent outbreaks of sarcoptes scabiei infestation in raccoon dogs (nyctereutes procyonoides) have been reported in japan. although many raccoon dogs are brought to kanazawa zoological garden (yokohama, kanagawa, japan) because of s. scabiei infestation and debilitation, some of them die of asthenia. the clinical status of severely debilitated raccoon dogs must be determined to save their lives. in this study, we compared hematological and serum biochemical values between severely debilitated a ... | 2011 | 21749931 |
| difference in age at first conception between early and late litters of feral raccoon (procyon lotor) in kanagawa prefecture. | due to the long parturition period of raccoons, we assumed that age at first conception of late born females was later than that of early born females. from march 2005 to september 2008, 201 females estimated to be younger than 24 months were separated into early- and late-born groups on the basis of their estimated birth month (to the nearest 2 months), and parous status and body mass index (bmi) were examined. age at first conception of late-born females (over 18 months old) was estimated to b ... | 2012 | 22167106 |
