| antigenic, phenotypic and molecular characterization confirms babesia odocoilei isolated from three cervids. | babesia isolates from an elk (cervus elaphus canadensis) and a caribou (rangifer tarandus caribou) with fatal infections were compared to babesia odocoilei (engeling isolate) from white-tailed deer (odocoileus virginianus) by experimental infection, serologic, and small subunit ribosomal rna (ssu rrna) gene sequence analysis studies. both the indirect fluorescent antibody test and immunoprecipitation assays demonstrated antigenic variation among the isolates. experimental infection studies showe ... | 2000 | 10941738 |
| ribosomal rna analysis of babesia odocoilei isolates from farmed reindeer (rangifer tarandus tarandus) and elk (cervus elaphus canadensis) in wisconsin. | piroplasms isolated from a farmed reindeer and elk in wisconsin were determined to be babesia odocoilei, based on morphology and ribosomal rna (rrna) analysis. different clinical manifestations were observed in the two host species. the reindeer was parasitemic and exhibited acute babesiosis resulting in death, while the elk showed no parasites in blood smears and no overt clinical signs of babesiosis. b. odocoilei was, however, readily cultured from elk erythrocytes. small subunit rrna gene seq ... | 2003 | 14505046 |
| new ruminant hosts and wider geographic range identified for babesia odocoilei (emerson and wright 1970). | babesia odocoilei was found to infect two previously unknown host species, desert bighorn sheep (ovis canadensis nelsoni) and musk oxen (ovibos moschatus), both of which are members of the family bovidae. previously, b. odocoilei has been reported in only cervidae hosts. new geographic regions where b. odocoilei infections have not been reported previously include pennsylvania and new york, where fatal babesiosis has occurred in reindeer (rangifer tarandus tarandus); new hampshire, where elk (ce ... | 2005 | 16456156 |
| babesia odocoilei infection in a saskatchewan elk (cervus elaphus canadensis) herd. | an 8-year-old female elk (cervus elaphus canadensis) cow, presented for chronic severe weight loss and unthriftiness, was diagnosed with babesia odocoilei infection based on blood smear evaluation, polymerase chain reaction (pcr), and dna sequence analysis. subsequently, velvet antler from a male that died acutely on the same farm was also pcr positive for babesia spp. both animals originated from a game ranch of saskatchewan-bred and -raised animals with no known history of tick exposure, but w ... | 2013 | 23780934 |
