Infectious bursal disease (Gumboro disease) - Nicolas Eterradossi - france OIE Reference Laboratory Reports Activities, 9 ToR To establish and maintain a network with other OIE Reference Laboratories designated for the same pathogen or disease and organise regular inter-laboratory proficiency testing to ensure comparability of results Infectious bursal disease (IBD) is seen in young domestic chickens worldwide and is caused by infectious bursal disease virus (IBDV). Signs can include depression, watery diarrhea, ruffled feathers, and dehydration. Morbidity is high and mortality is usually low, but some very virulent strains are capable of causing 60% or higher mortality. Gumboro is a highly contagious chickens disease caused by the infectious bursal disease virus (IBDV) that provokes a immunosuppression and chicken death at the age of 3 to 6 weeks of life. It is worldwide distributed and is highly contagious, therefore is responsible of great economic losses in .

Infectious bursal disease (IBD) is an acute, highly contagious disease of young chickens, caused by infectious bursal disease virus (IBDV) (van den Berg, ; Eterradossi and Saif, ; Mahgoub, ; Muller et al., ).First recognized in Gumboro, Delaware (USA) in , the disease was initially referred to as avian nephrosis, and later became known as Gumboro disease or infectious bursitis. Newcastle disease (ND) and infectious bursal disease (IBD) are the two most dreaded viral diseases of poultry in Nigeria as they cause severe economic losses in domestic and wild bird populations resulting from illness, reduced egg production, immunosuppression, and death following infection with pathogenic strains of their respective causative. Infectious bursal disease (IBD) is an economically important disease affecting poultry production worldwide. Previous experimental studies indicated that IBD live vaccination may induce transient immunosuppression, leading to suboptimal vaccine responses and therefore insufficient protection against other pathogens.

Infectious bursal disease (IBD) is seen in young domestic chickens worldwide and is caused by infectious bursal disease virus (IBDV). Signs can include depression, watery diarrhea, ruffled feathers, and dehydration. Morbidity is high and mortality is usually low, but some very virulent strains are capable of causing 60% or higher mortality.
