| 中文描述 | 牛隻的病毒性下痢，是因為感染了黃病毒科，瘟疫病毒屬的病毒所引發。此類的病毒，可以感染免疫力正常，但之前未曾感染過此病毒的牛隻。臨床症狀多發生於年輕小牛，老年牛隻則常在血清檢查中發現曾被感染的證據。依據臨床症狀以及病毒培養或病毒免疫螢光染色等檢驗做診斷。懷孕的母牛感染此疾病，會產下眼睛或腦部有病變的小牛。人工授精時若造成母牛感染，也會使懷孕率下降。在感染的小牛或成年牛身上，會發現血小板數量減少、血小板功能異常或出血的狀況。曾經發生過因為注射活毒疫苗，或是注射了被BVD病毒汙染的疫苗而發病的案例。在臨床症狀很嚴重的病患，癒後要審慎評估(guarded)。 |

| 英文描述 | Bovine virus diarrhea follows infection of immunocompetent but previously uninfected cattle with BVD virus, a member of the family Flaviviridae, genus PESTIVIRUS. Clinical disease most common in young; older cattle often have serologic evidence of exposure. Diagnose by clinical signs and demonstration of virus by culture or immunofluorescence. Pregnant cattle can produce calves with ocular or cerebellar disease and infection of susceptible females around the time of artificial insemination might lower the pregnancy rate. Findings in calves and adults can include thrombocytopenia, platelet dysfunction, and hemorrhages. Has occurred following vaccination with live virus vaccines, including vaccines for other viral agents which became contaminated by BVD virus. The prognosis is guarded when signs are severe. |
