| an outbreak of trixacarus caviae infestation of guinea pigs at an animal petting facility and an evaluation of the safety and suitable dose of selamectin treatment. | abstract in june 2009, 27 guinea pigs kept at an animal petting facility at a zoo in kanagawa prefecture, japan, were observed to scratch intensely, weaken, and develop lesions. three sarcoptiform mites were found in skin scrapings taken from affected areas of 2 guinea pigs and were identified as trixacarus caviae by morphological examination. this result confirmed the presence of t. caviae in japan. for treatment, 13.6-18.75mg/head of selamectin was administered in a topical preparation applied ... | 2011 | 21506831 |
| prevalence of cryptosporidium parvum infections in weaned piglets and fattening porkers in kanagawa prefecture, japan. | fecal samples from 232 weaned piglets (1 and 3 months old) and 252 fattening porkers (6 months old) in 8 stock-raising farms located in kanagawa prefecture, japan, from june 1998 to june 2000 were examined to determine the prevalence of cryptosporidium infection. detection of oocysts was performed using the ethyl acetate fecal concentration method and immunofluorescent staining. c. parvum oocysts were identified in 77 (33.2%) 1-3 months old weaned piglets from four farms. the odds of excreting a ... | 2001 | 11326125 |
| antigenic characteristics and genome composition of a naturally occurring recombinant influenza virus isolated from a pig in japan. | we performed antigenic analysis of the haemagglutinin and neuraminidase subunits of a recombinant virus (a/swine/kanagawa/2/78) isolated from a pig in japan in 1978, using a series of monoclonal antibodies to h1 (hsw1) haemagglutinin and n2 neuraminidases of h2n2 and h3n2 viruses. results obtained in haemagglutination inhibition tests with five monoclonal antibodies to the haemagglutinin of a/nj/8/76 (h1n1) revealed that the haemagglutinin of three h1n1 and the recombinant viruses were indisting ... | 1983 | 6198440 |
| the possible origin h1n1 (hsw1n1) virus in the swine population of japan and antigenic analysis of the isolates. | virus isolation and serological studies on swine sera collected during 1973 to 1978 showed that h1n1 (hsw1n1) influenza viruses first appeared in the swine population of japan about may 1977. with the exception of one strain, both haemagglutinin and neuraminidase subunits of all the h1n1 viruses isolated from swine in japan and from pigs imported from north america were antigenically indistinguishable from those of a/nj/8/76 virus, suggesting the introduction of swine influenza virus into japan ... | 1982 | 6182266 |
| outbreaks of swine vesicular disease in japan: virus isolation and epizootiological survey. | outbreaks of a vesicular disease occurred among pigs in kanagawa and ibaraki prefectures in japan in november, 1973. another outbreak was observed in aichi prefecture in december. the clinical signs of the disease observed included fever and vesicular lesions on the coronary bands, bulbs of the heel and in the interdigital spaces. in some pigs, vesicular lesions were observed on the snout, tongue and skin overlying the legs and abdomen. all the vesicular samples produced cytopathic changes on cu ... | 1975 | 174009 |
| genetic heterogeneity of porcine and ruminant pestiviruses mainly isolated in japan. | the genetic variability of porcine and ruminant pestiviruses was studied by comparative nucleotide sequence analysis of 73 isolates (42 porcine and 31 ruminant), including 65 japanese isolates (35 porcine and 30 ruminant). the 5'-untranslated region (utr) amplified by reverse transcriptase-polymerase chain reaction (rt-pcr) was determined by direct sequencing and phylogenetic analysis was performed from the nucleotide sequence data. most porcine isolates were divided into two major subgroups, cl ... | 1999 | 10068129 |
| continued circulation of reassortant h1n2 influenza viruses in pigs in japan. | in 1991 and 1992, h1n2 influenza a viruses were isolated from the lungs of pigs with overt signs of respiratory disease at farms in the chiba and kanagawa prefectures of japan. to determine the genetic origin of these isolates, we phylogenetically analyzed partial nucleotide sequences of their genes. the results indicate that influenza viruses possessing the n2 of human influenza virus and seven other gene segments of classical h1n1 swine influenza virus, which were first isolated in 1980, have ... | 1998 | 9787660 |
