| ticks (acari: ixodidae) of the nile monitor on rusinga island, kenya. | in the course of a study of ticks of livestock, five nile monitor lizard specimens were caught and examined for ticks. although none of the tick species infesting livestock were found on the reptiles, a large number of adults and presumed nymphs and larvae of aponomma flavomaculatum (lucus) and adults of amblyomma sparsum (neumann) were collected. the ticks demonstrated a distinct predilection for their attachment sites. this is the second report of a. flavomaculatum from this part of kenya. | 1990 | 2332875 |
| 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 |
| 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 |
| introduction of potential heartwater vectors and other exotic ticks into florida on imported reptiles. | following the discovery of establishment of the african tortoise tick amblyomma marmoreum in florida, the present study was undertaken to determine the extent of introduction of exotic ticks into florida on imported reptiles. exotic ticks were identified on 29 (91%) of 32 reptile premises in 18 counties of florida. the ticks, found on a variety of imported tortoises, snakes, and monitor lizards, belonged to 4 amblyomma species (a. marmoreum, amblyomma nuttalli, amblyomma sabanerae, and amblyomma ... | 2000 | 10958443 |
| evidence of cowdria ruminantium infection (heartwater) in amblyomma sparsum ticks found on tortoises imported into florida. | amblyomma marmoreum and a. sparsum ticks were collected from tortoises imported into florida from africa and were tested for cowdria ruminantium infection using a c. ruminantium-specific pcs20 polymerase chain reaction assay. in i shipment imported from zambia, 15 of the 38 a. sparsum male ticks collected from the leopard tortoises (geochelone pardalis) were found to be positive for infection with c. ruminantium. in contrast, all 148 a. marmoreum tested were negative for c. ruminantium infection ... | 2000 | 11128494 |

| ticks (acari: ixodidae) associated with wildlife and vegetation of haller park along the kenyan coastline. | this artcile describes the results obtained from a tick survey conducted in haller park along the kenyan coastline. the survey aimed at evaluating tick-host associations, assessing tick population density, and providing baseline information for planning future tick control and management in the park. ticks (2,968) were collected by handpicking from eight species of wildlife and by dragging in 14 selected sites within the park. a considerable proportion of ticks were also collected from leaves, s ... | 2006 | 17017210 |
| emerging tick-borne disease in african vipers caused by a cowdria-like organism. | heartwater is a tick-borne infectious disease caused by the rickettsial organism cowdria ruminantium, currently ehrlichia ruminantium. it poses an imminent threat to the western hemisphere, where it could cause mortality in cattle and other ruminant livestock in excess of 70%. it has been reported in the caribbean; and its vector, amblyomma sparsum, has been found on imported african spurred tortoises (geochelone sulcata) and leopard tortoises (geochelone pardalis) in southern florida in the uni ... | 2006 | 17135546 |
| progress and obstacles in vaccine development for the ehrlichioses. | ehrlichia are tick-borne obligately intracellular bacteria that cause significant diseases in veterinary natural hosts, including livestock and companion animals, and are now considered important zoonotic pathogens in humans. vaccines are needed for these veterinary and zoonotic human pathogens, but many obstacles exist that have impeded their development. these obstacles include understanding genetic and antigenic variability, influence of the host on the pathogen phenotype and immunogenicity, ... | 2010 | 20822349 |
| detection of rickettsia and ehrlichia spp. in ticks associated with exotic reptiles and amphibians imported into japan. | one of the major routes of transmission of rickettsial and ehrlichial diseases is via ticks that infest numerous host species, including humans. besides mammals, reptiles and amphibians also carry ticks that may harbor rickettsia and ehrlichia strains that are pathogenic to humans. furthermore, reptiles and amphibians are exempt from quarantine in japan, thus facilitating the entry of parasites and pathogens to the country through import. accordingly, in the current study, we examined the presen ... | 2015 | 26207382 |
| ticks imported to europe with exotic reptiles. | it is known that traded exotic animals carry with them an immense number of associated symbionts, including parasites. reptiles are no exception. most of the imported reptiles originate from tropical countries and their possibility to carry potentially dangerous pathogens is high. according to cites, europe is currently the main reptile importer in the world. despite this, there is no review or analysis available for the risk related to the importation of tick-borne diseases with traded reptile ... | 2015 | 25913453 |
| 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 |
| molecular detection of tick-borne pathogen diversities in ticks from livestock and reptiles along the shores and adjacent islands of lake victoria and lake baringo, kenya. | although diverse tick-borne pathogens (tbps) are endemic to east africa, with recognized impact on human and livestock health, their diversity and specific interactions with tick and vertebrate host species remain poorly understood in the region. in particular, the role of reptiles in tbp epidemiology remains unknown, despite having been implicated with tbps of livestock among exported tortoises and lizards. understanding tbp ecologies, and the potential role of common reptiles, is critical for ... | 2017 | 28620610 |
