ehrlichia spp. in cervids from california.blood samples from six mule deer (odocoileus hemionus hemionus), 15 black-tailed deer (o. hemionus columbianus), and 29 elk (cervus elaphus nannodes) were assayed for human monocytic and human granulocytic ehrlichiosis (hge) by polymerase chain reaction (pcr), dna sequencing, and serology to determine whether or not cervids are involved in the maintenance of these potential human pathogens in california (usa). the deer were sampled in august to october 1992-95. the 29 tule elk from point reyes n ...19989813842
prevalence of antibodies to spotted fever group rickettsia spp. and ehrlichia spp. in coyotes (canis latrans) in oklahoma and texas, usa.coyotes (canis latrans) are commonly infested with ticks, including amblyomma americanum, the predominant vector of ehrlichia chaffeensis and ehrlichia ewingii; dermacentor variabilis, an important vector of rickettsia rickettsii; and amblyomma maculatum, a major vector of rickettsia parkeri, a spotted fever group (sfg) rickettsia. to determine the degree to which coyotes are infected with or exposed to tick-borne bacterial disease agents, serum samples collected from coyotes in oklahoma and tex ...201323778619
the first isolation, in vitro propagation, and genetic characterization of ehrlichia canis in israel.ehrlichia canis, the etiologic agent of canine ehrlichiosis, was isolated in israel from a naturally infected dog with acute signs of the disease. the organism designated e. canis 611, was passaged experimentally to a beagle, from which it was propagated in primary canine monocytes. the organism was then grown in vitro in a continuous canine cell line, dh82. nine beagles subsequently injected with whole e. canis-infected blood all developed typical symptoms of ehrlichiosis. an indirect immunoflu ...19968686178
a serological survey of ehrlichia canis, ehrlichia equi, rickettsia rickettsii, and borrelia burgdorferi in dogs in oklahoma.serum samples from 259 dogs were tested for antibodies to ehrlichia canis, ehrlichia equi, rickettsia rickettsii, and borrelia burgdorferi using the indirect fluorescent antibody test. the sera were obtained from submissions to the oklahoma animal disease diagnostic laboratory during a 14-month period from june 1986 through july 1987. the rate for positive antibody titers to e. canis was 53%, to e. equi was 33%, to r. rickettsii was 38%, and to b. burgdorferi was 18%. higher percentages of sera ...19892518693
babesia canis rossi infection in a texas dog.a 5-month-old intact male boerboel dog, imported from south africa 1 week previously, was presented to a texas veterinarian for lethargy, anorexia, and labored breathing. the dog was febrile, anemic, leukopenic, thrombocytopenic, and slightly azotemic. results of the idexx snap-4dx enzyme immunoassay were negative for dirofilaria immitis antigen and antibodies against ehrlichia canis, borrelia burgdorferi, and anaplasma phagocytophilum. an edta blood sample analyzed at oklahoma state university ...201121790699
