In 2005 a Mycoplasma species was isolated from ocular-conjunctival swabs from an adult male Alpine ibex (Capra ibex) from the Valle d'Aosta Region, Northern Italy. The animal suffered from bilateral ocular discharge with diffuse inflammation, severe corneal involvement of the left eye and mild corneal opacity of the right eye. Histologic examination(More)
A serological survey was carried out in the northern prefectures of Hokkaido, Iwate and Aomori in Japan, for the presence of antibodies against Toxoplasma gondii, Chlamydiapsittaci var. ovis, Mycobacterium paratuberculosis, Coxiella burnetii, Brucella spp., Leptospirosis and Orf virus (ORFV). Out of 267 samples tested, highest overall prevalence (28.78%)(More)
Ovine sera collected in the Prefectures of Hokkaido, Aomori and Iwate in the Northern Japan were examined for the presence of antibodies against Respiratory syncytial virus (RSV), bovine Herpesvirus type 1 (infectious bovine rhinotracheitis: IBR) and Parainfluenza virus type 3 (PIV3) using serum neutralisation (SN) and enzyme-linked immunosorbent assay(More)
We examined previously identified border disease virus (BDV) strains by using a newly proposed genotyping procedure based on palindromic nucleotide substitutions (PNS) in the 5'-untranslated region (UTR), and found 22 (41.5%) out of 53 strains of BDV in the nucleotide sequence databases are not of BDV. All the 22 ovine pestivirus strains were allocated to(More)
Sixteen clinical strains of classical swine fever virus (CSFV) isolated in Japan were subjected to analyses of nucleotide sequence variations in the 5' end and NS5B regions of the genome. These isolates were divided into three genovars, CSFV-1, CSFV-2 and CSFV-3, based on palindromic nucleotide substitutions at the three variable loci in the 5' untranslated(More)
Ovine herpesvirus 2 (OvHV-2) causes sheep-associated malignant catarrhal fever (SA-MCF), and is responsible for economic losses in cattle and other susceptible species around the world. A survey of 154 serum samples from 14 flocks in 3 Japanese prefectures (Hokkaido, Aomori and Iwate) was undertaken between 2007 and 2008 to test for antibodies to OvHV-2.(More)
The first epidemiological survey of Border disease virus (BDV) was undertaken in small ruminants in Japan. Ovine sera, collected from the northern prefectures of Hokkaido, Aomori and Iwate, were examined for the presence of antibodies against BDV using the neutralization peroxidase-linked antibody test. Twenty-nine (17.6%) of one hundred and sixty-five(More)
Bovine viral diarrhoea virus 2 (BVDV-2) strains demonstrated in cattle, sheep and adventitious contaminants of biological products were evaluated by the palindromic nucleotide substitutions (PNS) method at the three variable loci (V1, V2 and V3) in the 5' untranslated region (UTR), to determine their taxonomic status. Variation in conserved genomic(More)
A survey for antibodies against caprine arthritis and encephalitis (CAE) virus was undertaken in north-west Syria. Out of 72 sera, using agar immuno-diffusion test, 12.5% showed a positive reaction. Despite the seropositiveness, no clinical evidence of the infection was found in the tested animals. The findings indicate that the infection is endemic in the(More)
A simple and practical method was developed for pestivirus genotyping based on analysis of the secondary structures in the 5'-untranslated region (UTR). Three stable stem-loop structures, V1, V2 and V3, predicted by computer in the 5'-UTR, included strictly conserved consensus base-pairings which are shared by all the genotypes of pestivirus or are(More)
