Seroprevalence of infectious bursal disease in non-vaccinated indigenous and exotic chickens on selected farms around Gaborone, Botswana.
نویسندگان
چکیده
Sera from nine out of 30 (30.0%) apparently healthy unvaccinated indigenous (Tswana) chickens had precipitating antibodies to infectious bursal disease (IBD) virus using the agar gel precipitation test. Similarly, sera from 11 out of 49 (22.4%) chickens of exotic breeds with no history of vaccination against IBD were positive for antibodies against the virus.

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...

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...
