The Pathogenicity of an Isolate of Infectious Bursal Disease Virus in Guinea Fowls
نویسندگان
چکیده
Five weeks old guinea fowls were inoculated intraocularly with a 20% bursal suspension containing a local Nigerian isolate of infectious burfa! disease virus (IBDV) which had a bursal lesion titre of 10· per 0.5 mI. No clinical signs were observed. Gross lesions were absent and microscopic lesions were not found in the bursa, spleen and kidney on days 3 and 5 post infection (PI). IBDV antigen was not detected in the bursa. Tests for IBDV precipitins in serum samples obtained on day 14 PI were also negative.

Pathogenicity Study and Restriction Enzyme Profile of a Recently Isolated Infectious Bursal Disease Virus in Iran
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%...

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...

Infectious bursal disease virus (IBDV) infects young chickens and causes serious lose to the poultry industry, worldwide. Previous attempts using purified bacterially expressed IBDV VP2 failed to elicit a protective immune response to the virus. This study was designed to investigate if the initial expressed protein contained neutralizing epitopes but became nonfunctional during purification st...

Background and Aims: Infectious bursal disease (IBD) is an acute contagious viral disease of birds worldwide. The causative virus induces a persistent immune suppression following destroy B lymphocytes precursors in bursal lymphoid follicles. Vaccination is the main strategy for prevention of the disease in commercial poultry industry. Materials and Methods: To produce a live vaccine against th...
متن کاملComparison of Pathogenicity and Serologic Response of Four Commercial Infectious Bursal Disease Live Vaccines.
Various commercial vaccines for immunization of broiler chickens against infectious bursal disease (IBD) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. In this study the pathogenicity and serologic response of four IBD vaccines, cloned D78®, Bursine-2®, Bursimune® and Cevac Gambo-L®, were evaluated in specific pathogen f...
