A study of infectious bursal disease (IBD) or 'Gumboro disease' seroprevalence rates in healthy, non-vaccinated indigenous scavenging chickens in northern Tanzania was conducted in November and December 2009 on 362 chickens raised in a traditional management system. Individual bird and flock-level information was collected using a semi-structured questionnaire, and serum samples were screened f...
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...
Sanitary constraints of raising turkey in north-west Benin were studied by using a survey and Haemagglutination Inhibition Test (HIT) to detect antibodies of Newcastle Disease (ND) and Avian Influenza (AI). We tested 85 serums from 7- to 24-month-old turkeys raised in 19 farms. ND prevalence rate was 54% but reactions on four sub-types of AI were negative. Mortality rates varied from 55 to 100%...
materials for this study were consisted of 100 carcasses of broiler chickens aged 14 to 60 which had died from respiratory problems and/or gumboro disease with diarrhea. these carcasses were submitted from local poultry farms to the department of poultry diseases of the veterinary college of islamic azad university, tabriz branch for post mortem examination. intestinal faecal from colac and cec...
Infectious bursal disease (IBD), also known as Gumboro disease, is a globally well-known disease with a significant socio-economic effect. For control of IBD, several commercial egg- and cell-based vaccines are prepared. The cell-based IBD vaccines are significantly cost-effective; however, it is essential to confirm their safety and efficacy. The main cell line used to product the cell-based I...

Virus mutations and their impact on vaccination against infectious bursal disease (Gumboro disease).
Infectious bursal disease (also known as Gumboro disease) is an immunosuppressive viral disease specific to chickens. In spite of all the information amassed on the antigenic and immunological characteristics of the virus, the disease has not yet been brought fully under control. It is still prevalent in properly vaccinated flocks carrying specific antibodies at levels normally high enough to p...
