A study was conducted to determine the prevalence of bovine herpesvirus-1 (BHV-1), which causes infectious bovine rhinotracheitis, in cattle destined for market in Southern Province, Zambia. A total of 116 nasal secretion samples were tested using the direct fluorescent antibody test, while blood samples from the same cattle were examined by a commercial enzyme-linked immunosorbent assay kit. T...
Bovine herpesvirus type 5 (BHV-5) is the causative agent of a fatal meningo-encephalitis in calves and is closely related to BHV-1 which causes infectious bovine rhinotracheitis. The gene encoding BHV-5 glycoprotein gH was sequenced. A high degree of conservation was found between BHV-1 and BHV-5 deduced gH amino acid sequences (86. 4%), which is also observed for all alphaherpesvirus gH sequen...
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 (ELISA) tests. Twenty-three animals (11.73...
This study was conducted at the Centre for Research, Teaching and Extension in Tropical Livestock (Centro de Investigación, Enseñanza y Extensión en Ganadería Tropical) of the Faculty of Veterinary Medicine of the National Autonomous University of Mexico. During the latter part of 1986 and throughout 1988 and 1989, the herd of Holstein x zebu cattle at the University was tested for IgG antibodi...
Bovine herpesvirus 1 (BHV-1) belongs to the Varicellovirus genus, Herpesviridae family and causes different respiratory, reproductive and nervous system disorders in cows, including infectious bovine rhinotracheitis (IBR). For determination of the genetic relationship of gB and gD – two of main BHV-1 glycoprotein genes in Iran with those in other countries, DNA fragments of 671 bp corresponding...
