Dogs as potential carriers of infectious bursal disease virus.

چکیده
In this study, the possibility that dogs could eventually be carriers of infectious bursal disease virus (IBDV) after having eaten (voluntarily or accidentally) IBDV-infected chicks has been evaluated. A single Beagle dog was fed chicks infected by a very virulent IBDV strain (vvIBDV). Afterwards, the presence and viability of IBDV in the faeces was assessed. Viable vvIBDV was detected in the dog's faeces for 2 days after the initial ingestion, which indicates excretion of vvIBDV. Comparison by molecular techniques of the administered and excreted virus using reverse transcription-polymerase Chain reaction and enzymatic digestion confirmed that the initial virus maintained the same characteristics after being excreted. We believe that this study could be of great interest for a better understanding of the epidemiology of IBD disease on farms where dogs live close to avian facilities.

The pathogenicity of a recent isolate of Infectious bursal disease virus (IBDV), IR499, isolated from a nonvaccinated flock with 17.5 % mortality rate in susceptible SPF chickens, chickens embryos and broilers was discussed. The molecular characterization of the virus based on the restriction fragment length polymorphism (RFLP) pattern was also investigated. The mortality rates were 85% and 22%...

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. The expression of heterologous proteins in P.pastoris is fast, simple and inexpensive. In this study, VP2 encoding gene of classical D78 IBDV was amplified using reverse transcription (RT) polymerase chain reaction (PCR) and cloned into pPICZαA vector...
