detection of bovine herpesvirus 1 sequences in yaks (bos grunniens) with keratoconjunctivitis, using a highly sensitive nested polymerase chain reaction.thirty-seven yaks (bos grunniens) with keratoconjunctivitis and 22 healthy yaks were used to investigate the role of bovine herpesvirus 1 (bohv-1) in keratoconjunctivitis in yaks. nucleic acid sequences of bohv-1 glycoproteins b and e were detected in conjunctival swabs from all yaks with keratoconjunctivitis using a nested polymerase chain reaction (pcr). in 21 yaks, bohv-1 sequences were detected along with moraxella bovis (m. bovis) and neisseria spp. the amplified bohv-1 sequences were ident ...201021309468
bovine herpesvirus-1 (bhv-1) - a re-emerging concern in livestock: a revisit to its biology, epidemiology, diagnosis, and prophylaxis.bovine herpesvirus-1 (bhv-1) is known to cause several diseases worldwide. it is a double-stranded dna virus consisting of 33 structural proteins out of which 13 are associated with the envelope. based on genomic analysis and viral peptide patterns, bhv-1 virus can be divided into several subtypes like bhv-1.1, bhv-1.2, and bhv-1.3. however, all subtypes are antigenically similar. the symptoms of the related diseases are mainly non-life-threatening but have a rather wide host range that limits a ...201323802762
epizootic hemorrhagic disease in yaks (bos grunniens).an epizootic of hemorrhagic disease associated with epizootic hemorrhagic disease virus serotype 2 (ehdv-2) infections in yaks from 5 herds occurred in colorado between august 21 and october 3, 2012. affected yaks presented with fever, lethargy, anorexia, dyspnea, and swollen conjunctivae. ulcerated dental pads, mucoid sanguineous nasal discharge, petechial hemorrhages in multiple organs, pulmonary edema, and serosanguinous fluid in the thorax, abdomen, and pericardial sac were observed at necro ...201323572453
prevalence of circulating antibodies to bovine herpesvirus 1 in yaks (bos grunniens) on the qinghai-tibetan plateau, china.bovine herpesvirus 1 (bohv-1) causes infections with many clinical signs, including rhinotracheitis, encephalitis, and genital lesions. the virus occurs worldwide in bovines, and in recent years, it has been reported in yaks (bos grunniens) inhabiting the tibetan plateau in china. however, there is little epidemiologic data describing bohv-1 infections in china's yak herds. we conducted a cross-sectional study on the qinghai-tibetan plateau (qtp) in china july 2011-july 2012 to estimate the prev ...201626555106
a serological survey of antibodies against bovine herpesvirus-1 in yak (poephagus grunniens) in arunachal pradesh in india.serum samples were collected from 254 yak (poephagus grunniens, presently bos grunniens) in different yak tracts of india. these samples were then screened by virus neutralisation test (vnt) and avidin-biotin enzyme-linked immunosorbent assay (ab-elisa) to study the seroprevalence of antibodies against bovine herpesvirus type 1 (bhv-1). the overall seroprevalence in yak was found to be 41% (105) by vnt and ab-elisa. the sex of the animal, whether it was on a farm or free-ranging and the location ...200920462162
serological evidence of bovine herpesvirus-1 (bohv-1) infection in yaks (peophagus grunniens) from the national research centre on yak, india.bovine herpesvirus-1 (bohv-1) causes a variety of disease syndromes including, respiratory, nervous and reproductive disorders both in domestic as well as wild bovines and the disease is prevalent throughout the world including india. in this study, serum samples of yaks were screened for serological evidence of bohv-1 in a yak farm with history of abortion and kerato-conjuctivitis by competition-elisa. the result of seroprevalence of bohv-1 infections in yaks (poephagus grunniens) revealed that ...201020143159
interferon-alpha genes from bos and bubalus bubalus.interferon-a genes were cloned from six breeds of three species of two genera (three chinese native cattle breeds of yellow cattle, wild yak and huanhu domestic yak, one european breed of holstein cow, and two water buffalo breeds of fuan water buffalo and fuzhong water buffalo) by direct pcr. the pcr products were directly inserted into the expression vector to be sequenced and expressed. sequence analysis showed that ifn-a genes of six clones were composed of 498 nucleotides, encoding a mature ...200616621760
