| parasites of domestic and wild animals in south africa. xxxviii. ixodid ticks collected from 23 wild carnivore species. | ixodid ticks were collected from 104 wild carnivores belonging to 23 species in various nature reserves and on several farms in all nine provinces of south africa. seven feral cats in a nature reserve were also examined. twenty-four tick species belonging to seven genera were recovered and identified. amongst these ticks we consider the adults of haemaphysalis leachi, haemaphysalis spinulosa, haemaphysalis zumpti, ixodes rubicundus, rhipicentor nuttalli, rhipicephalus simus and rhipicephalus tur ... | 2000 | 11206391 |
| hosts, seasonal occurrence and life cycle of rhipicentor nuttalli (acari: ixodidae). | there are only two species worldwide within the genus rhipicentor, namely rhipicentor bicornis and rhipicentor nuttalli and both occur only in africa. rhipicentor nuttali has a widespread distribution in south africa and the present investigation was initiated to elucidate its host preference, seasonality and life cycle. rock elephant shrews, elephantulus myurus were examined for ticks at four localities in the free state province, one in gauteng province and two in limpopo province, south afric ... | 2002 | 12356163 |
| elephant shrews as hosts of immature ixodid ticks. | two hundred and seventy-three elephant shrews, consisting of 193 elephantulus myurus, 67 elephantulus edwardii and 13 animals belonging to other species, were examined for ixodid ticks at 18 localities in south africa and namibia. the immature stages of ixodes rubicundus, rhipicentor nuttalli, rhipicephalus warburtoni and a rhipicephalus pravus-like tick were the most numerous of the 18 tick species recovered. substantial numbers of immature rhipicephalus arnoldi, rhipicephalus distinctus and rh ... | 2005 | 16562732 |
| the identification of a shared immunogen present in the salivary glands and gut of ixodid and argasid ticks. | the identification of a 70-kda immunogen present in salivary gland extracts of several ixodid species, namely hyalomma truncatum (sweating-sickness-inducing (ss+) and non-inducing (ss-) strains), hyalomma marginatum rufipes and rhipicephalus evertsi evertsi, is reported. the immunogen was identified by western blots using a monoclonal antibody of the igm isotype directed against a 70-kda immunogen present in the salivary glands of (ss-) female h. truncatum ticks. cross-reactivity with the gut of ... | 1992 | 1446571 |
| surveillance for viral and parasitic pathogens in a vulnerable african lion (panthera leo) population in the northern tuli game reserve, botswana. | african lion ( panthera leo ) numbers are decreasing rapidly and populations are becoming smaller and more fragmented. infectious diseases are one of numerous issues threatening free-ranging lion populations, and low-density populations are particularly at risk. we collected data on the prevalence and diversity of viral and parasitic pathogens in a small lion population in eastern botswana. during 2012 and 2014, blood samples were collected from 59% (n=13) of the adult-subadult lions in the nort ... | 2017 | 27669009 |
| complex interactions within the ectoparasite community of the eastern rock sengi (elephantulus myurus). | concomitant infection with more than one parasite species is the rule in nature. since co-infecting parasites are exploiting the same host, interspecific interactions at the infracommunity level are likely. the nature of such interactions can be expected to affect the distribution of parasites within host populations. intraspecific interactions within the infracommunity are not easily discernible from cross-sectional studies and the focus of most of these studies lies on relationships between en ... | 2015 | 25830115 |
| tick paralysis in australia caused by ixodes holocyclus neumann. | ticks are obligate haematophagous ectoparasites of various animals, including humans, and are abundant in temperate and tropical zones around the world. they are the most important vectors for the pathogens causing disease in livestock and second only to mosquitoes as vectors of pathogens causing human disease. ticks are formidable arachnids, capable of not only transmitting the pathogens involved in some infectious diseases but also of inducing allergies and causing toxicoses and paralysis, wit ... | 2011 | 21396246 |
| evidence for interspecific interactions in the ectoparasite infracommunity of a wild mammal. | co-infection with multiple parasite species is commonly observed in nature and interspecific interactions are likely to occur in parasite infracommunities. such interactions may affect the distribution of parasites among hosts but also the response of infracommunities to perturbations. however, the response of infracommunities to perturbations has not been well studied experimentally for ectoparasite communities of small mammal hosts. | 2016 | 26830510 |
