Serum samples from 51 apparently healthy breeding bulls were screened for bovine herpesvirus-1 (BHV-1) antibodies using an avidin-biotin enzyme-linked immunosorbent assay, revealing a sero-positive prevalence rate of 45.09%. Semen samples were then collected from 12 of the sero-positive and 12 of the sero-negative bulls and tested for BHV-1 antigen using(More)
Staphylococcus aureus is a Gram-positive bacterium that causes a variety of diseases, including bovine mastitis, which has severe economic consequences. Standard antibiotic treatment results in selection of resistant strains, leading to need for an alternative treatment such as bacteriophage therapy. Present study describes isolation and characterization of(More)
Brucellosis is a worldwide zoonosis and a significant cause of loss of health in human and animals. Conventionally, definitive diagnosis is done by isolation of brucellae which is time consuming, technically demanding and may be hazardous. The present study was aimed to develop PCR assay based on evolutionarily conserved outer membrane protein 22 gene for(More)
Mesenchymal stem cells are multipotent stem cells capable of differentiating into various cell types, including osteocytes, chondrocytes, adipocytes, myocytes, and tenocytes. They are being highly investigated in tissue engineering and regenerative studies. This study was carried out to isolate, identify and examine the differentiation potential of canine(More)
The present investigation was conducted to study the genetic heterogenicity and molecular polymorphism among the field isolates and vaccine strains of infectious bursal disease virus (IBDV). Samples of bursa of Fabricius from 15 suspected outbreaks of infectious bursal disease (IBD) were subjected to agar gel precipitation test (AGPT), virus isolation and(More)
AIM The active domains (TIR and NACHT) of the pattern recognition receptors (PRRs: Toll-like receptors [TLRs] and nucleotide-binding oligomerization domain [NOD]-like receptors [NLR], respectively) are the major hotspots of evolution as natural selection has crafted their final structure by substitution of residues over time. This paper addresses the(More)
Canine distemper (CD), caused by canine distemper virus (CDV) is a highly contagious disease that infects a variety of carnivores. Sequence analysis of CDVs from different geographical areas has shown a lot of variation in the genome of the virus especially in haemagglutinin gene which might be one of the causes of vaccine failure. In this study, we(More)
Marek's disease (MD), caused by Marek's disease virus (MDV), is a highly contagious neoplastic disease of chicken that can be prevented by vaccination. However, in recent years many cases of vaccine failure have been reported worldwide as chickens develop symptoms of MD in spite of proper vaccination. Distinct polymorphism and point mutations in Meq gene of(More)
Marek's disease, caused by lymphotropic alphaherpesvirus, is one of the most economically significant diseases of poultry. Despite the ubiquitous use of vaccination to control losses, Marek's disease still affects poultry farming worldwide with an estimated annual loss up to US $2 billion. There is a need for a simple and rapid diagnostic method for early(More)
Bovine herpesvirus-1 (BHV-1) glycoprotein C (gC) is an immunodominant protein that is believed to play a role in initial viral attachment. In the present study a recombinant baculovirus was constructed by incorporating BHV-1 gC coding gene to characterize the expression of the glycoprotein in infected Spodoptera frugiperda cells. The BHV-1 complete gC gene(More)
