ecology of keystone virus, a transovarially maintained arbovirus. | our studies in the pocomoke cypress swamp of maryland have shown that key strain of ce is endemic and is carried by the floodwater mosquito a. atlanticus. the virus is transmitted transstadially in nature, as evidenced by our recovery of virus from larvae and males of this species. serologic evidence, both here and elsewhere, indicates that vertebrates are infected with key, but their role in the transmission cycle remains unknown. we have found several animals, for example, the gray squirrel, t ... | 1975 | 20017 |
experimental infection of vertebrates of the pocomoke cypress swamp, maryland with keystone and jamestown canyon viruses. | experimental studies were conducted to assess the susceptibility of white-tailed deer (odocoileus virginianus), gray squirrels (sciurus carolinensis), and cottontail rabbits (sylvilagus floridanus) to jamestown canyon (jc) and/or keystone (key) virus infection. viremia occurred in 5 of 6 deer inoculated with jc virus; however, all deer developed key virus neutralizing antibody. based on the observation that antibody elicited by primary infection of deer with either key or jc virus exhibited part ... | 1979 | 453437 |
serologic evidence of jamestown canyon and keystone virus infection in vertebrates of the delmarva peninsula. | serological data accumulated during the past decade indicated that a variety of feral and domestic animals of the delaware-maryland-virginia (delmarva) peninsula were infected with jamestown canyon (jc) and/or keystone (key) viruses (bunyaviridae, california serogroup). neutralizing (n) antibody to jc virus was most prevalent in white-tailed deer, sika deer, cottontail rabbits and horses. key virus n antibody was detected most frequently in gray squirrels and domestic goats. n antibody indicativ ... | 1982 | 7149110 |
