| the ecology of the african vectors of heartwater, with particular reference to amblyomma hebraeum and amblyomma variegatum. | the hosts, sites of attachment, life cycle, habitat requirements and seasonal abundance of amblyomma astrion, amblyomma cohaerens, amblyomma gemma, amblyomma hebraeum, amblyomma lepidum, amblyomma marmoreum, amblyomma pomposum, amblyomma sparsum, amblyomma tholloni and amblyomma variegatum, the 10 potential vectors of heartwater in africa, are listed. factors influencing the distribution and abundance of the ticks as well as interactions with other species and the role of predators and pathogens ... | 1987 | 3329326 |
| an updated list of the ticks of ghana and an assessment of the distribution of the ticks of ghanaian wild mammals in different vegetation zones. | twenty one species of ticks belonging to five genera of the family ixodidae (order acari, sub-order ixodida) - amblyomma, haemaphysalis, hyalomma, ixodes and rhipicephalus (including the sub-genus rhipicephalus (boophilus)) - were collected from 1260 mammals, representing 29 species, 14 families and 6 orders, in four vegetation zones in ghana during the period 1971-1978. four other species were collected from humans in 1977. in all, eight species appeared to be new records for ghana: amblyomma t ... | 2004 | 15191626 |
| detection of "rickettsia sp. strain uilenbergi" and "rickettsia sp. strain davousti" in amblyomma tholloni ticks from elephants in africa. | to date, 6 tick-borne rickettsiae pathogenic for humans are known to occur in africa and 4 of them were first identified in ticks before being recognized as human pathogens. | 2007 | 17683629 |
| dissemination of spotted fever rickettsia agents in europe by migrating birds. | migratory birds are known to play a role as long-distance vectors for many microorganisms. to investigate whether this is true of rickettsial agents as well, we characterized tick infestation and gathered ticks from 13,260 migratory passerine birds in sweden. a total of 1127 ixodes spp. ticks were removed from these birds and the extracted dna from 957 of them was available for analyses. the dna was assayed for detection of rickettsia spp. using real-time pcr, followed by dna sequencing for spec ... | 2010 | 20052286 |
| novel rickettsia and emergent tick-borne pathogens: a molecular survey of ticks and tick-borne pathogens in shimba hills national reserve, kenya. | ticks are important vectors of emerging and re-emerging zoonoses, the majority of which originate from wildlife. in recent times, this has become a global public health concern that necessitates surveillance of both known and unknown tick-borne pathogens likely to be future disease threats, as well as their tick vectors. we carried out a survey of the diversity of ticks and tick-borne pathogens in kenya's shimba hills national reserve (shnr), an area with intensified human-livestock-wildlife int ... | 2017 | 28011185 |
| 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 |
