| pathogenicity of a highly pathogenic avian influenza virus, a/chicken/yamaguchi/7/04 (h5n1) in different species of birds and mammals. | outbreaks of highly pathogenic avian influenza (hpai) have been occurring in domestic poultry in asia since 1996. in the beginning of 2004, hpai outbreaks were caused by h5n1 virus in two farms and a group of pet chickens in different areas of japan. in the present study, the pathogenicity of a/chicken/yamaguchi/7/04 (h5n1), which had been isolated from a dead chicken during the first outbreak in japan, was assessed in chickens, quails, budgerigars, ducklings, mice, and miniature pigs by experim ... | 2006 | 16502281 |
| possible factors influencing the immunoglobulin m concentration in swine colostrum. | the immunoglobulin (ig) m concentration in swine colostrum was determined by the single radial immunodiffusion method, using 157 samples collected from the same number of farm-raised sows in yamaguchi prefecture of japan during 1976 and 1977. the mean igm value was 4.16 +/- 1.11 mg/ml, and the maximum and minimum values were 7.74 mg/ml and 1.50 mg/ml, respectively. to elucidate the possible factors influencing the igm concentration in swine colostrum, the following 12 items were surveyed in the ... | 1981 | 7294479 |
| simple and specific method for detection of antibodies against hepatitis e virus in mammalian species. | hepatitis e virus (hev) is the causative agent of hepatitis e, a food- and water-borne disease. in developed countries, consumption of meats from pigs, wild boars and deer is a major source of infection. although hev and hev-related viruses have been detected in many animal species, their zoonotic potential and prevalence has not been completely understood. to detect anti-hev antibody in mammalian species, a simple enzyme-linked immunosorbent assay (elisa) was established using extract from cell ... | 2016 | 27732880 |
| influenza a virus infection in japanese wild boars (sus scrofa leucomystax). | serum samples were collected from 385 wild boars between 2010 and 2013 to examine the seroprevalence of influenza a virus (iav) in japan. antibodies against iav were identified using a commercial kit in 13 wild boars (3.4%). to identify the serotypes, positive sera were examined by virus-neutralization test using representative serotypes and strains. three wild boars in yamaguchi and four in tochigi showed the highest antibody titers against the pandemic h1n1 2009 virus and classical swine h1n1 ... | 2017 | 28321029 |
| high prevalence of hepatitis e virus in wild boar (sus scrofa) in yamaguchi prefecture, japan. | hepatitis e virus (hev) causes a food- and water-borne disease in humans, and japanese wild boar (sus scrofa leucomystax) meat is one of the most important sources of infection in japan. we tested 113 serum samples from wild boar captured in shimonoseki city, yamaguchi prefecture, japan from 2010 to 2012. serum samples were tested by enzyme-linked immunosorbent assay (elisa) using virus-like particles as antigen and nested reverse-transcription pcr (rt-pcr). anti-hev igg antibodies were detected ... | 2014 | 24506423 |
