| a serologic survey of pronghorns in alberta and saskatchewan, 1970-1972. | to determine the exposure of free-ranging pronghorns (antilocapra americana ord) to selected pathogens, serum samples were obtained from 33 live-trapped animals from southwestern saskatchewan in 1970, and from 26 and 51 animals from southeastern alberta, in 1971 and 1972, respectively. antibodies were found to the agents of parainfluenza 3, bovine virus diarrhea, eastern and western encephalomyelitis, infectious bovine rhinotracheitis and the chlamydial group. no serologic reactors were found to ... | 1975 | 167203 |

| western equine encephalitis virus in saskatchewan garter snakes and leopard frogs. | western equine encephalitis virus was isolated from two naturally infected snakes on first bleeding and from seven others at subsequent bleedings, both with and without preliminary chilling. one snake, with neither detectable virus nor serum neutralizing antibodies when first bled, developed viremia later. viremia in garter snakes has a cyclic rhythm independent of the temperature of the environment. virus was isolated from 6 frogs, and 50 out of 179 had detectable serum neutralizing antibodies. ... | 1966 | 5919753 |
| laboratory studies on the transmission of western equine encephalitis virus by saskatchewan mosquitoes. i. culex tarsalis. | a saskatchewan strain of the mosquito culex tarsalis, transmitted a local strain of western equine encephalitis virus from chick to chick, between four and 44 days after an infective blood meal. at incubation temperatures of 69 and 75 degrees f, 120 transmissions occurred out of a possible 141, and all but seven of these were by single infected mosquitoes. at 75 degrees f virus titers in individual mosquitoes were more uniform and transmission was more efficient, than at 69 degrees f, although i ... | 1972 | 4259935 |
| antibody against western equine encephalitis virus occurring in the serum of garter snakes (colubridae: thamnophis) in saskatchewan. | a study was made of feeding and temperature as factors affecting the appearance of western equine encephalitis (wee) virus-neutralizing serum (vns) antibodies in the serum of garter snakes (thamnophis spp). eighty snakes were collected in the field, held in captivity under controlled conditions, and bled at frequent intervals. the sera were examined by standard procedures for the presence of wee vns-antibodies. it was found that snakes held between 10-28 degrees c showed conversion and intermitt ... | 1971 | 4251413 |
| natural infections of richardson's ground squirrels with western equine encephalomyelitis virus, saskatchewan, canada, 1964-1973. | a survey (1964-1973) was conducted on naturally occurring western equine encephalomyelitis (wee) virus infections of richardson's ground squirrels (rgs) in agricultural areas of saskatchewan. the survey included both serology and virus isolation attempts on live-trapped wild squirrels. throughout the study, seropostive squirrels were found in the known enzootic regions of the province each summer. the infections rate was high (11.6% of 250) in the epidemic year of 1965 and low (less than 2% o ... | 1975 | 1148947 |
