Canarypox viruses (CNPV) carrying the coding sequence of VP2 protein from infectious bursal disease virus (IBDV) were obtained. These viruses were able to express VP2 protein in vitro and to induce IBDV-neutralizing antibodies when inoculated in specific pathogen-free chickens demonstrating that CNPV platform is usefulness to develop immunogens for chickens.

The study was conducted to determine the prevalence of infectious bursal disease virus (IBDV) at different ages in commercial boilers. From Oct 2003 to Nov 2004, bursa samples collected from both vaccinated as well non-vaccinated commercially reared broiler chickens suspected of having infectious bursal disease were analyzed for the presence of IBDV using reverse transcriptase polymerase chain ...

infectious bronchitis (ib) and newcastle disease (nd) are highly contagious and the most economically important diseases of the poultry affecting respiratory tract and causing economic losses in poultry industry throughout the world. in the present study, the simultaneous detection and differentiation of causative agents of these diseases were investigated using duplex-rt-pcr. rna was extracted...

It is widely recognized that fragile states are key symptoms of under-development in many parts of the world. Such states are incapable of delivering basic services to their citizens and political violence is commonplace. As of yet, mainstream development economics has not dealt in any systematic way with such concerns and the implications for development assistance. This paper puts forward a f...

Sequencing and phylogenetic analysis based on the nucleotide sequence of the gene encoding VP2 protein was carried out in order to characterize the agent of two outbreaks of infectious bursal disease in layer flocks in the state of Minas Gerais in 2004. The results indicate the outbreaks could be related to the vaccinal virus.

In this study, immunohistochemistry was used to clarify the early stages of viral kinetics and cycliccourse of IBDV, IR499, which has been described earlier as a very virulent strain (vvIBDV). Fifteen, 4-week-old SPF chickens were inoculated with 10³ EID50 of vvIBDV, IR499, via oculo/nasal route. Five birdsserved as controls, and inoculated with phosphate buffered saline (PBS). The birds were t...
