apparent incompetence of dermacentor variabilis (acari: ixodidae) and fleas (insecta: siphonaptera) as vectors of borrelia burgdorferi in an ixodes dammini endemic area of ontario, canada. | from april to october 1990, white-footed mice, peromyscus leucopus (rafinesque), were examined for ectoparasites on long point, ontario, the only endemic area for ixodes dammini clifford, spielman, piesman & corwin and borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner known in canada. larval and nymphal i. dammini and dermacentor variabilis (packard), and adult fleas orchopeas leucopus (baker), epitedia wenmanni (rothschild), and ctenophthalamus pseudagrytes baker were common on ... | 1991 | 1941949 |

dna typing of rickettsiae in naturally infected ticks using a polymerase chain reaction/restriction fragment length polymorphism system. | we used the polymerase chain reaction/restriction fragment length polymorphism (pcr/rflp) rickettsial typing system of regnery and others to rapidly identify rickettsiae in naturally infected ticks. unlike previously described methods, our pcr assays type rickettsiae directly from tick tissues without first isolating the organisms. we collected 226 adult dermacentor andersoni ticks in the bitterroot mountains of western montana and analyzed them for possible rickettsial infection by hemolymph te ... | 1994 | 7906924 |
erysipelothrix rhusiopathiae, serotype 17, septicemia in moose (alces alces) from algonquin park, ontario. | erysipelothrix rhusiopathiae septicemia was diagnosed in three of four moose found dead in algonquin provincial park, ontario, canada, in the spring of 1989. type 17 e. rhusiopathiae was isolated from liver, lung, kidney, and lymph nodes of affected animals, which were in poor body condition, and suffering hair loss associated with tick (dermacentor albipictus) infestations. microscopic lesions consisted of mild, multifocal, necrotizing myocarditis, sarcocystosis, and lymph node atrophy. the bac ... | 1994 | 7933291 |
