Neurological disorder in cattle associated with bovine herpesvirus 4

Isolation of Bovine Herpesvirus-1 (BoHV-1) From Latently Infected/Carrier Cattle in Ahvaz

Bovine herpesvirus 1 (BoHV-1) is one of the most important infectious viruses of cattle which is considered as the causative agent of several clinical conditions in this species. Hence, we tried to isolate a local strain of the virus from carrier cattle in Ahvaz based on a strategy for reactivation of the latent infection in hosts having antibodies against the virus. Thus, 20 cattle were examin...

Mammary lesions associated with bovine herpesvirus type 4 in a cow with clinical mastitis.

Intranuclear eosinophilic inclusion bodies were seen in the lactiferous duct and sinus epithelium of mammary tissues collected from a cow with clinical mastitis. Transmission electron microscopy revealed herpesvirus particles in these cells. Immunolabeling against anti bovine herpesvirus type 4 (BHV-4) rabbit serum was detected in nuclei that had intranuclear inclusion bodies. In addition, BHV-...

Association of Bovine Lactoferrin Gene with Mastitis in Frieswal Cattle

ThirtyFrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. Polymorphism of cow lactoferrin (LTF) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results showed that LFT gene pro...

Detection of bovine herpesvirus 2 and bovine herpesvirus 4 DNA in trigeminal ganglia of naturally infected cattle by polymerase chain reaction.

Establishment of latent infection within specific tissues in the host is a common biological feature of the herpesviruses. In the case of bovine herpesvirus 2 (BoHV-2), latency is established in neuronal tissues, while bovine herpesvirus 4 (BoHV-4) and ovine herpesvirus 2 (OvHV-2) latent virus targets on cells of the monocytic lineage. This study was conducted in quest of BoHV-2, BoHV-4 and OvH...
