| babesia bicornis sp. nov. and theileria bicornis sp. nov.: tick-borne parasites associated with mortality in the black rhinoceros (diceros bicornis). | a novel babesia species, designated babesia bicornis sp. nov., was identified in three black rhinoceroses (diceros bicornis) that died in wildlife areas in tanzania and south africa. screening of black rhinoceroses in south africa revealed, in addition to b. bicornis, a second parasite, designated theileria bicornis sp. nov. | 2003 | 12734294 |
| piroplasm parasites of white rhinoceroses (ceratotherium simum) in the kruger national park, and their relation to anaemia. | as part of a larger survey to map the geographical distribution of babesia and theileria parasites in the southern african rhinoceros population, white rhinoceroses were sampled during routine immobilisations in the kruger national park. polymerase chain reaction (pcr) and reverse line blot (rlb) hybridisation assays were used to screen for the presence of piroplasms and complete blood counts were used to assess associated changes in clinical parameters. of the 195 rhinoceroses sampled, 71 (36.4 ... | 2011 | 21826836 |
| epidemiology of theileria bicornis among black and white rhinoceros metapopulation in kenya. | a huge effort in rhinoceros conservation has focused on poaching and habitat loss as factors leading to the dramatic declines in the endangered eastern black rhinoceros (diceros bicornis michaeli) and the southern white rhinoceros (ceratotherium simum simum). nevertheless, the role disease and parasite infections play in the mortality of protected populations has largely received limited attention. infections with piroplasmosis caused by babesia bicornis and theileria bicornis has been shown to ... | 2015 | 25604678 |
| novel babesia and hepatozoon agents infecting non-volant small mammals in the brazilian pantanal, with the first record of the tick ornithodoros guaporensis in brazil. | taking into account the diversity of small terrestrial mammals of the pantanal, the present study aimed to verify the occurrence of infection by ehrlichia spp., anaplasma spp., rickettsia spp., hepatozoon spp., babesia spp. and parasitism by ticks in non-volant small mammals collected in the brazilian pantanal. samples of blood, liver and spleen were collected from 64 captured animals, 22 marsupials and 42 rodents. pathogen detection was performed by the use of genus-specific polymerase chain re ... | 2016 | 26782931 |
| three novel haplotypes of theileria bicornis in black and white rhinoceros in kenya. | piroplasms, especially those in the genera babesia and theileria, have been found to naturally infect rhinoceros. due to natural or human-induced stress factors such as capture and translocations, animals often develop fatal clinical piroplasmosis, which causes death if not treated. this study examines the genetic diversity and occurrence of novel theileria species infecting both black and white rhinoceros in kenya. samples collected opportunistically during routine translocations and clinical i ... | 2016 | 24906113 |
| protozoan and bacterial pathogens in tick salivary glands in wild and domestic animal environments in south africa. | a total of 7364 ticks belonging to 13 species was collected from 64 game animals (belonging to 11 species) and from 64 livestock animals (cattle and sheep) living in close vicinity at 6 localities in 3 south african provinces (free state, mpumalanga, and limpopo). the geographic distribution of all tick species was congruent with the literature except for haemaphysalis silacea. from each infested host, a maximum of 10 males and 10 females of each tick species were dissected to isolate the saliva ... | 2014 | 24378080 |
