| california serogroup and powassan virus infection of cats. | one hundred and seventy five sera from cats in ontario, canada, were tested for hemagglutination inhibition (hi) antibodies to three arboviruses; namely, powassan (pow) of the flavivirus serogroup, and snowshoe hare (ssh) and jamestown canyon (jc) viruses of the california (cal) serogroup. all sera were negative for antibodies to pow virus. twelve cats possessed cal serogroup antibodies including 3 with antibodies to ssh alone, 6 with antibodies to jc alone, and 3 with antibodies to both ssh and ... | 1987 | 2825952 |
| arbovirus infections in several ontario mammals, 1975-1980. | 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 ... | 1986 | 3017527 |
| prevalence of neutralizing antibody to jamestown canyon virus (california group) in populations of elk and moose in northern michigan and ontario, canada. | blood samples were collected from free-ranging elk (cervus elaphus) harvested in michigan's northern lower peninsula, from moose (alces alces) relocated from ontario's algonquin provincial park to michigan's upper peninsula, and from moose from michigan's isle royale national park. sera were tested by serum dilution neutralization tests in vero cell culture for neutralizing antibody to california serogroup viruses, in particular jamestown canyon (jc), la crosse/snowshoe hare (lac/ssh), and trivi ... | 1986 | 3503129 |
| california encephalitis virus activity in mosquitoes and horses in southern ontario, 1975. | a study was undertaken in 1975 to determine california encephalitis virus activity in southern ontario. three thousand and sixty-one mosquitoes, primarily aedes species, were divided into 104 pools and inoculated into suckling mice. isolates of snowshoe hare virus were obtained from one pool each of aedes fitchii and a. triseriatus mosquitoes collected in the guelph area. serological testing of horse sera revealed extensive virus activity in southern ontario and indicated that horses may serve a ... | 1978 | 34475 |
| virus isolations from mosquitoes in southern ontario, 1976 and 1977. | following the 1975 epidemic of st. louis encephalitis (sle) in ontario, programs were instituted to monitor virus activity in mosquito populations during 1976 and 1977. mosquitoes were trapped with cdc light traps and co2 cone traps, pooled by species, and tested for virus by intracerebral inoculation of suckling mice. in 1976, 51 175 mosquitoes were tested. sle virus was isolated from two mixed pools of culex pipiens--c. restuans mosquitoes. five isolations of california serogroup viruses were ... | 1980 | 6103747 |
