| prevalence of rickettsia-like organisms and spotted fever group rickettsiae in ticks (acari: ixodidae) from zimbabwe. | the prevalence of rickettsia-like organisms in ticks from zimbabwe was determined using the hemolymph test. amblyomma hebraeum had the highest prevalence of rickettsia-like organisms. other species with rickettsia-like organisms included amblyomma sparsum, amblyomma variegatum, hyalomma marginatum rufipes, ripicephalus simus, haemaphysalis leachi, amblyomma rhinocerotis, and hyalomma truncatum. ticks with no demonstrable rickettsia-like organisms infection were boophilus decoloratus, haemaphysal ... | 1995 | 8551500 |
| 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 |
| host specialization in ticks and transmission of tick-borne diseases: a review. | determining patterns of host use, and the frequency at which these patterns change, are of key importance if we are to understand tick population dynamics, the evolution of tick biodiversity, and the circulation and evolution of associated pathogens. the question of whether ticks are typically host specialists or host generalists has been subject to much debate over the last half-century. indeed, early research proposed that morphological diversity in ticks was linked to host specific adaptation ... | 2013 | 24109592 |
| history and development of research on wildlife parasites in southern africa, with emphasis on terrestrial mammals, especially ungulates. | the history of wildlife parasitology in south africa, and to some extent southern africa, is reviewed, giving a brief overview of the early years and following its development from the founding of the onderstepoort veterinary institute in 1908 until the turn of the century. an emphasis is placed on game species. the main findings on protozoan parasites, including those of carnivores, are presented, starting in the 1890s and leading up to the first decade of the 21st century. important developmen ... | 2014 | 25830101 |
| coendangered hard-ticks: threatened or threatening? | the overwhelming majority of animal conservation projects are focused on vertebrates, despite most of the species on earth being invertebrates. estimates state that about half of all named species of invertebrates are parasitic in at least one stage of their development. the dilemma of viewing parasites as biodiversity or pest has been discussed by several authors. however, ticks were omitted. the latest taxonomic synopses of non-fossil ixodidae consider valid 700 species. though, how many of th ... | 2011 | 21554736 |
| parasites of domestic and wild animals in south africa. xlix. ticks (acari: ixodidae) infesting white and black rhinoceroses in southern africa. | the objectives of the study were to determine the species composition of ticks infesting white and black rhinoceroses in southern africa as well as the conservation status of those tick species that prefer rhinos as hosts. ticks were collected opportunistically from rhinos that had been immobilised for management purposes, and 447 white rhinoceroses (ceratotherium simum) and 164 black rhinoceroses (diceros bicornis) were sampled in south africa, 61 black rhinos in namibia, 18 white and 12 black ... | 2017 | 28155285 |
