| 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 |
| genotypically unique babesia spp. isolated from reindeer (rangifer tarandus tarandus) in the united states. | two morphologically dissimilar babesia spp. were cultured from reindeer (rangifer tarandus tarandus) in placer county, calif. the smaller isolate, designated rd61, was morphologically similar to babesia odocoilei. serum from rd61-infected reindeer reacted equally strongly to b. odocoilei and rd61 parasites in the indirect fluorescent antibody (ifa) test. small subunit ribosomal rna (ssu rrna) gene-sequence analysis showed 99.0% identity to that of b. odocoilei. the larger piroplasm, designated r ... | 2002 | 12049456 |
| 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 |
| diagnosis and treatment of babesia odocoilei in captive reindeer (rangifer tarandus tarandus) and recognition of three novel host species. | two captive reindeer (rangifer tarandus tarandus) at a new york zoological institution were diagnosed with babesia odocoilei. clinical signs consistent with acute babesiosis included fever, hemoglobinuria, and hemolytic anemia. both episodes were precipitated by stressful events that may have compromised their immunocompetence. the diagnosis was confirmed by visualization of intraerythrocytic parasites on stained blood smears, polymerase chain reaction, and speciation of the babesia by sequencin ... | 2009 | 19368255 |
