In 1983, vesicular stomatitis entered the state of California through infected cattle purchased in Idaho and sold to 5 California dairies. This study examined management, environmental, and host factors which were thought to be associated with disease spread. The use of coarse roughage and hard-pelleted concentrates, the presence of uneaten feed potentially contaminated with virus-laden saliva, increased interpen movement of cows, poor ground surface conditions, poor milking hygiene, and poor teat sanitation were management factors observed to be associated with clinical signs. The amount of milk production, age, or days in milk of individual cows seemed to have an important role in the spread of clinical disease. Recommendations are given for control and prevention of clinical signs and, therefore, the severity of disease during epizootics of vesicular stomatitis in California dairies.
1983年，水疱性口炎通过从爱达荷州购入并售予加利福尼亚州5家奶牛场的感染牛传入加利福尼亚州。本研究调查了被认为与疾病传播相关的管理、环境和宿主因素。观察到的与临床症状相关的管理因素包括使用粗饲料和硬颗粒精饲料、存在可能被含病毒唾液污染的未食用饲料、奶牛间互窜增加、地面状况差、挤奶卫生差以及乳头清洁卫生差。个体奶牛的产奶量、年龄或泌乳天数似乎在临床疾病传播中起重要作用。针对加利福尼亚州奶牛场水疱性口炎流行期间临床症状的控制和预防以及疾病严重程度给出了建议。
