UNLABELLED Influenza D virus (FLUDV) is a novel influenza virus that infects cattle and swine. The goal of this study was to investigate the replication and transmission of bovine FLUDV in guinea pigs. Following direct intranasal inoculation of animals, the virus was detected in nasal washes of infected animals during the first 7 days postinfection. High viral titers were obtained from nasal tu...

Veterinary Ireland Journal Volume 3 Number 5 259 SOUTH-EAST REGION BoVINE ABoRtIoN AND CoNgENItAl DISEASE Schmallenberg Virus Kilkenny RVL suspected Schmallenberg Virus as the cause of a bizarre deformity of the head of a full term bovine foetus. Both upper and lower jaws were short and upturned and there was a single central eye (Fig 1). There was also arthrogryposis and hydranencephaly. PCR w...

Glycoprotein D (gD) is the major structural protein of infectious bovine rhinotracheitis virus (IBRV). It can induce both humoral and cellular immunity thus it is a preferable protein for IBR diagnostic reagent. Regarding to DNAstar analysis, the major antigenic region of the gD fragment was amplified by PCR using the IBRV genomic DNA as a template, and subsequenly constructed into the recombin...

A western blot assay using purified recombinant bovine immunodeficiency virus gag protein has been developed for detection of bovine immunodeficiency virus antibodies in bovine serum samples. The test was standardized with known bovine immunodeficiency virus positive and negative bovine serum samples and the monoclonal antibody to gag protein. Both naturally and experimentally infected cattle s...

Aim: Four viral pathogens, bovine viral diarrhea virus (BVDV), and bovine herpes virus type 1 (BHV-1), bovine parainfluenza type 3 virus (PI-3V), bovine respiratory syncytial virus (BRSV) are mainly associated with bovine respiratory diseases that cause major economic losses in the dairy cattle industry. This study aimed to document exposure of cattle in Saudi Arabia to infectious BVDV, BHV-1, ...

Neoplasms of the lymphatic tissue in the bovine species can be classified into two major types according to clinical and epidemiological data: 1. The juvenile form of bovine leukosis, with three different clinical forms: the multicentric, thymic, and cutaneous forms. The juvenile form is rare and shows a random geographical distribution. It has also been called sporadic bovine leukosis. 2. The ...

Bovine herpesvirus type 1 (BHV-1) is an important pathogen that can initiate bovine respiratory disease complex. Like other members of the subfamily Alphaherpesvirinae, BHV-1 establishes latency in sensory neurons. The latency-related (LR) gene expresses a family of alternatively spliced transcripts in infected sensory neurons that have the potential to encode several LR proteins. An LR mutant ...

The pathogenicity of Felis catus gammaherpesvirus 1 (FcaGHV1), a common infection of domestic cats, is unknown. To explore an association between FcaGHV1 detection and feline lymphoma, a retrospective, cross-sectional, disease-association study was conducted. The infection status of all cats for feline immunodeficiency virus and feline leukaemia virus was determined. Neither a molecular diagnos...

The isolation and identification of an adventitious viral agent, infectious bovine rhinotracheitis virus, in one lot of A549 cells from a commercial supplier is described in this report. The presence of infectious bovine rhinotracheitis virus in A549 cells was unexpected and has caused problems in the diagnosis of infections in clinical specimens in three laboratories.
