growth characteristics in cell culture and pathogenicity in mice of two terrestrial rabies strains indigenous to canada.two strains of street rabies virus from striped skunks (mephitis mephitis) were used to infect either a murine neuroblastoma (na 1300) or a baby hamster kidney (bhk-21/c13) cell culture and the cell infection rates were noted during 4 days postinfection. these cultures were then passaged for four consecutive passages, and the viruses obtained in the supernatant fluids of passage 4 were then treated as original isolates and used to infect both neuroblastoma and baby hamster kidney cells. the mort ...19883378201
rabies in insectivorous bats of western canada, 1979 to 1983.a total of 1,745, 362, and 536 bats collected in alberta, british columbia, and saskatchewan, respectively, was tested for rabies virus between 1979 and 1983. only one (0.1%) of 769 bats collected at random from buildings was infected with rabies virus in contrast to 95 (5%) of 1,874 symptomatic, rabies-suspect bats submitted for testing. the pattern of infection in the rabies-suspect bats was similar in alberta and saskatchewan, but differed in british columbia. rabies was diagnosed in four spe ...19863735577
major antigenic groups of rabies virus in canada determined by anti-nucleocapsid monoclonal antibodies.a total of 123 rabies virus isolates from various geographical areas in canada were characterized by a panel of 43 anti-nucleocapsid monoclonal antibodies. four major antigenic groups are found in terrestrial mammals: "canadian arctic" from ontario, quebec and the northwest territories; "south-eastern georgian bay" from ontario; "south mid-central skunk" from alberta, saskatchewan and manitoba; and "brook's, alberta skunk" from a restricted area in alberta. bat isolates can be divided into 4 maj ...19863769442

spatial and temporal dynamics of rabies virus variants in big brown bat populations across canada: footprints of an emerging zoonosis.phylogenetic analysis of a collection of rabies viruses that currently circulate in canadian big brown bats (eptesicus fuscus) identified five distinct lineages which have emerged from a common ancestor that existed over 400 years ago. four of these lineages are regionally restricted in their range while the fifth lineage, comprising two-thirds of all specimens, has emerged in recent times and exhibits a recent demographic expansion with rapid spread across the canadian range of its host. four o ...201020406385
porcine teschovirus polioencephalomyelitis in western canada.beginning in 2002, a small number of pig farms in western canada began reporting 4-7-week-old pigs with bilateral hind-end paresis or paralysis. low numbers of pigs were affected, some died, most had to be euthanized, and those that survived had reduced weight gains and neurological deficits. necropsies revealed no gross lesions, but microscopic lesions consisted of a nonsuppurative polioencephalomyelitis, most severe in the brain stem and spinal cord. the lesions were most consistent with a vir ...201121398466
