| 中文描述 | 黏膜疾病,牛慢性病毒性下痢,發生在羊的持續性感染,有非細胞病變起源的牛病毒性下痢病毒(黃病毒科,瘟疫病毒屬)晚一點會開始感染有細胞病變的病毒遺傳因子型,可能由於從非胞病品種在持續性載體發生突變所致.牛的持續性感染通常會不能發展成循環的抗體.由於馬足板層炎或是趾間壞死會是跛腳的.圍繞冠狀帶的皮膚可以是紅且水腫.口部損傷會盈虧.疾病已經發生隨著肝病毒的接種. |
| 英文描述 | Mucosal disease, chronic bovine viral diarrhea, occurs in cattle persistently infected with noncytopathogenic BVD virus (family Flaviviridae, genus PESTIVIRUS) that later become infected with a cytopathic viral biotype, possibly due to mutation from noncytopathic strains in persistent carriers. Cattle with persistent infection usually fail to develop circulating antibody. Can be lame due to laminitis or interdigital necrosis. Skin around the coronary band can be red and swollen. Oral lesions can wax and wane. Disease has occurred following vaccination with live virus. |
