傳染性華氏囊病(infection bursal disease)
病源:Birnaciridae
血清型:2種，其中血清一型才對雞有致病性
病源:Birnaciridae
血清型:2種，其中血清一型才對雞有致病性
傳播途徑:水平/機械性，不藉卵
病程:病毒感染華氏囊後(4日)可見華氏囊腫大為正常的2倍---8日後呢萎縮到正常的1/3
臨床症狀:白色下痢(咖噌配猴猴!!台語!!)
疫苗:VP2抗原基因重組疫苗

The Harderian gland may also be severely affected following infection of 1dayold chicks with IBDV. Normally, the gland is infiltrated and populated with plasma cells as the chicken ages (57, 248). Infection with IBDV prevented this infiltration. From 1–weekofage, the glands of infected chickens had populations of plasma cells 5–10 fold fewer than those of uninfected controls (57). In contrast, broilers inoculated with IBDV at 3weeks of age had plasma cell necrosis in the Harderian gland 5–14days PI, and the plasma cells were reduced by 51% at 7days PI (58). Reduction in plasma cells, however, was transient, and the numbers were normal after 14 days.
