Serological studies for arboviruses were conducted on 725 animal sera collected in 22 Ontario townships between 1975 and 1980 including 44 coyote (Canis latrans), 277 red fox (Vulpes vulpes), 192 raccoon (Procyon lotor) and 212 striped skunk (Mephitis mephitis). Hemagglutination inhibition antibodies to two flaviviruses, namely St. Louis encephalitis and Powassan were found in 50% of coyote, 47% of skunk, 26% of fox and 10% of raccoon sera. Similarly, hemagglutination inhibition antibodies to a California serogroup virus, snowshoe hare, were found in 12% of fox, 7% of skunk, 7% of raccoon and 5% of coyote sera. No antibodies were detected to two alphavirus, namely eastern equine encephalitis and western equine encephalitis, antigens. This study affirms the endemic presence of Powassan and snowshoe hare virus and further delineates the scope of St. Louis encephalitis activity in Ontario.
1975年至1980年间，在安大略省22个乡镇收集了725份动物血清，对其中的虫媒病毒进行了血清学研究，这些动物包括44只郊狼（犬属）、277只赤狐（赤狐属）、192只浣熊（浣熊属）和212只条纹臭鼬（臭鼬属）。在50%的郊狼血清、47%的臭鼬血清、26%的狐狸血清和10%的浣熊血清中发现了针对两种黄病毒的血凝抑制抗体，这两种黄病毒分别是圣路易斯脑炎病毒和波瓦桑病毒。同样，在12%的狐狸血清、7%的臭鼬血清、7%的浣熊血清和5%的郊狼血清中发现了针对加利福尼亚血清群病毒雪兔病毒的血凝抑制抗体。未检测到针对两种甲病毒（即东部马脑炎病毒和西部马脑炎病毒）抗原的抗体。这项研究证实了波瓦桑病毒和雪兔病毒在当地的存在，并进一步划定了安大略省圣路易斯脑炎活动的范围。
