| tularaemia transmitted by ticks (dermacentor andersoni) in saskatchewan. | common wood ticks (dermacentor andersoni) collected from saskatchewan landing provincial park, saskatchewan in the spring of 1982 transmitted a lethal tularaemia infection to four of six rabbits. francisella tularensis organisms were isolated from tissues taken from the dead rabbits and identified from subcultures using an indirect immunofluorescent antibody assay. one human associated with the animals developed symptoms of tularaemia and, after successful therapy, had a significant increase in ... | 1983 | 6667429 |
| a canadian bison isolate of anaplasma marginale (rickettsiales: anaplasmataceae) is not transmissible by dermacentor andersoni (acari: ixodidae), whereas ticks from two canadian d. andersoni populations are competent vectors of a u.s. strain. | anaplasma marginale theiler is a tick-borne rickettsial pathogen of cattle with a global distribution in both temperate and tropical regions. the pathogen is endemic in regions within the united states, whereas the canadian cattle population is considered to be free ofa. marginale. farmed bison, bison bison l., in central saskatchewan have been found to be infected with a. marginale; however, there is no evidence of transmission from bison to cattle. we tested a saskatchewan bison isolate of a. ... | 2006 | 17017236 |
| genetic variation in the 16s mitochondrial dna gene of two canadian populations of dermacentor andersoni (acari: ixodidae). | the rocky mountain wood tick, dermacentor andersoni stiles, 1908, is of medical and veterinary importance because it can transmit pathogenic agents to humans, domestic livestock, and wildlife. the preferred attachment sites of d. andersoni adults and their ability to induce paralysis in hosts vary among populations, which may have a genetic basis. in this study, polymerase chain reaction (pcr)-single-strand conformation polymorphism (sscp) analyses and dna sequencing were used to determine the g ... | 2009 | 19496416 |
| novel genotypes of anaplasma bovis, "candidatus midichloria" sp. and ignatzschineria sp. in the rocky mountain wood tick, dermacentor andersoni. | bovine anaplasmosis, caused by anaplasma marginale, is a vector-borne disease that is enzootic in many parts of the usa. although dermacentor andersoni, a major vector of a. marginale, occurs in canada, the canadian cattle herds are currently considered free of bovine anaplasmosis. there have been two outbreaks of the disease in the province of saskatchewan, but these have been linked to the importation of infected animals. however, the distribution of bovine anaplasmosis may alter with range ex ... | 2011 | 21334146 |
