Neutralization tests were done on sera from 141 horses from high elevation regions of California. Antibody prevalences to Jamestown Canyon, snowshoe hare, and California encephalitis viruses in the California serogroup and Northway virus in the Bunyamwera serogroup were 55%, 43%, 18%, and 46%, respectively. In 51 horses from rural low elevation regions, seroprevalences were 31%, 35%, 35%, and 37%, respectively. Twenty-four horses from a suburban lowland area were seronegative, except for a single horse with a low titer to snowshoe hare virus. Seroprevalence to Jamestown Canyon and snowshoe hare viruses was associated with increasing age. Only 2 of 177 rodents from the Sierra Nevada had antibodies to Northway virus; none had antibodies to Jamestown Canyon or snowshoe hare viruses.
对来自加利福尼亚高海拔地区的141匹马的血清进行了中和试验。加利福尼亚血清群中针对詹姆斯敦峡谷病毒、雪兔病毒和加利福尼亚脑炎病毒以及布尼亚姆韦拉血清群中针对诺斯韦病毒的抗体阳性率分别为55%、43%、18%和46%。在来自农村低海拔地区的51匹马中，血清阳性率分别为31%、35%、35%和37%。来自郊区低地地区的24匹马血清学阴性，只有一匹马对雪兔病毒的滴度较低。对詹姆斯敦峡谷病毒和雪兔病毒的血清阳性率与年龄增长有关。在内华达山脉的177只啮齿动物中，只有2只具有针对诺斯韦病毒的抗体；没有一只具有针对詹姆斯敦峡谷病毒或雪兔病毒的抗体。
