| seroepidemiological survey of morbillivirus infection in kuril harbor seals (phoca vitulina stejnegeri) of hokkaido, japan. | serological analysis was performed to detect morbillivirus infection in kuril harbor seals in hokkaido, japan. serum samples were collected from the seals at nosappu (231 sera), akkeshi (16), and erimo (75) between 1998 and 2005. antibodies to phocine distemper virus (pdv) were detected by elisa in seals from nosappu and erimo. antibodies to pdv were found in 56% (5/9) of the sampled seals from nosappu in 1998, versus only 5% (3/66) for 2003, 1% (1/79) for 2004, and 1% (1/77) for 2005. these sug ... | 2006 | 17201196 |
| serological evidence of influenza a virus infection in kuril harbor seals (phoca vitulina stejnegeri) of hokkaido, japan. | for proper management and conservation of the kuril harbor seal (phoca vitulina stejnegeri) through disease control, serological analysis was performed for influenza a virus infection in free-ranging seals in hokkaido, japan. serum samples were collected from seals at nosappu (231 seals), akkeshi (16) and erimo (75), between 1998 and 2005, and were analyzed by elisa. antibodies to the influenza a virus were detected only in seals from nosappu. the incidences were 11% (1/9), 3% (2/66), 12% (7/59) ... | 2007 | 17409641 |
| seroepidemiology of toxoplasma gondii and neospora caninum in seals around hokkaido, japan. | serological analysis was performed to detect toxoplasma gondii and neospora caninum infection in seals in hokkaido. serum samples were collected from 322 kuril harbor seals (phoca vitulina stejnegeri) at nosappu, akkeshi and erimo, from 46 spotted seals (p. largha) at nosappu, erimo, yagishiri island, hamamasu and syakotan, and from 4 ribbon seals (p. fasciata) and a bearded seal (erignathus barbatus) at nosappu between 1998 and 2006. recombinant surface antigen of t. gondii (sag2t) and n. canin ... | 2007 | 17485927 |
| growth variation in skull morphology of kuril harbor seals (phoca vitulina stejnegeri) and spotted seals (phoca largha) in hokkaido, japan. | we examined morphological growth variations in skull features between the kuril harbor seal and the spotted seal in hokkaido, japan. skulls from 80 kuril harbor seals and 41 spotted seals were collected, and we measured 29 metric and 6 non-metric cranial characteristics. three growth classes were defined according to the postnatal developmental stage: pups (0 year), subadults (1-4 years old) and adults (more than 5 years old). we detected sexual dimorphism in kuril harbor seal pups, subadults, a ... | 2009 | 20025123 |
| serologic evidence of brucella infection in pinnipeds along the coast of hokkaido, the northernmost main island of japan. | brucella infection in hokkaido was serologically surveyed in four species of pinnipeds inhabiting cape erimo during 2008-2013 and the shiretoko peninsula in 1999, by enzyme-linked immunosorbent assay using brucella abortus and b. canis as antigens. anti-brucella positive sera showed higher absorbance to b. abortus than b. canis in almost all samples. anti-b. abortus antibodies were detected in serum samples from 24% (n=55) of western pacific harbor seals (phoca vitulina stejnegeri) in cape erimo ... | 2017 | 28262966 |
| a case of cleft palate in a kuril seal (phoca vitulina stejnegeri), from hokkaido, japan. | a male pup kuril seal (phoca vitulina stejnegeri) from hokkaido, japan, was observed with a unilateral and total cleft of the primary palate. complications included a supernumerary tooth, hypoplasia and asymmetry of the face, and deformation of the eyeball and external auditory meatus. an accompanying pneumonia may have resulted from water flowing into the respiratory system due to imperfect closure of the nostril by the cleft. no other abnormalities were found. | 1992 | 1512890 |
