Book Description
This is a comprehensive work summarizing the current state of knowledge of the biology of the hard ticks (Acari: Ixodidae) of Southern Africa (South Africa, Namibia, Botswana, Swaziland, Lesotho and Maputo Province, Mozambique). It provides an overview of the history of tick research in Southern Africa and the evolution of our knowledge of the ticks’ distribution and biology, as well as the methods used to determine tick distribution, abundance and host preference. The morphologies of most of the tick species known to occur in Southern Africa are described and illustrated, and their distributions are described and mapped in relation to the biomes of the region. The known hosts for each tick species are listed, and the tick’s host preferences are discussed. Information on most species life cycle in the laboratory and the field, and their seasonal occurrence, is summarized. The diseases of animals and humans transmitted or caused by each tick species are summarized in relation to tick ecology. Aspects of the biology of the major hosts relevant to tick infestations are described, and extensive tick/host and host/tick lists are provided for each country

Book Description
This book has been designed to summarize current, essential information for every one of the world’s 700+ hard tick species. Under each species name, we will cite the original description, followed by information on type depositories, known stages, distribution (by zoogeographic region and ecoregion), hosts, and human infestation (if any). Each species account will also include a list of salient references and, where necessary, remarks on systematic status. We envision eight chapters: six devoted to the major ixodid tick genera (Amblyomma, Dermacentor, Haemaphysalis, Hyalomma, Ixodes, Rhipicephalus), one covering eight minor genera (including two that are fossil), and a concluding summary chapter. There will be two tables on host associations and zoogeography in each major genus chapter, as well as five tables in the summary chapter, for a total of 17 tables. No similar synopsis of the world’s hard tick species exists in any language.

Book Description
Of the 758 species of hard ticks (family Ixodidae) currently known to science, 137 (18%) are found in the Neotropical Zoogeographic Region, an area that extends from the eastern and western flanks of the Mexican Plateau southward to southern Argentina and Chile and that also includes the Greater and Lesser Antilles and the Galápagos Islands. This vast and biotically rich region has long attracted natural scientists, with the result that the literature on Neotropical ticks, which are second only to mosquitoes as vectors of human disease and are of paramount veterinary importance, is enormous, diffuse, and often inaccessible to non-specialists. In this book, three leading authorities on the Ixodidae have combined their talents to produce a summary of essential information for every Neotropical tick species. Under each species name, readers will find an account of the original taxonomic description and subsequent redescriptions, followed by an overview of its geographic distribution and host relationships, including a discussion of human parasitism. Additional sections provide detailed analyses of tick distribution by country and zoogeographic subregion (the Caribbean, southern Mexico and Central America, South America, and the Galápagos Islands), together with a review of the phenomenon of invasive tick species and examination of the many valid and invalid names that have appeared in the Neotropical tick literature. The text concludes with an unprecedented tabulation of all known hosts of Neotropical Ixodidae, including the tick life history stages collected from each host. This book is an invaluable reference for biologists and biomedical personnel seeking to familiarize themselves with the Neotropical tick fauna.

Book Description
Ticks of the family Ixodidae, commonly known as hard ticks, occur worldwide and are second only to mosquitoes as vectors of agents pathogenic to humans. Of the 729 currently recognized hard tick species, 283 (39%) have been implicated as human parasites, but the literature on these species is both immense and scattered, with the result that health professionals are often unable to determine whether a particular tick specimen, once identified, represents a species that is an actual or potential threat to its human host. In this book, two leading tick specialists provide a list of the species of Ixodidae that have been reported to feed on humans, with emphasis on their geographical distribution, principal hosts, and the tick life history stages associated with human parasitism. Also included is a discussion of 21 ixodid species that, while having been found on humans, are either not known to have actually fed or may have been misidentified. Additionally, 107 tick names that have appeared in papers on tick parasitism of humans, and that might easily confuse non-taxonomists, are shown to be invalid under the rules of zoological nomenclature. Although the species of ticks that attack humans have long attracted the attention of researchers, few comprehensive studies of these species have been attempted. By gleaning and analyzing the results of over 1,100 scientific papers published worldwide, the authors have provided an invaluable survey of hard tick parasitism that is unprecedented in its scope and detail.

Book Description
Due to prevailing environmental and climatic conditions South Africa hosts one cheetah subspecies (Acinonyx jubatus jubatus) and a wide range of tick-borne protozoa such as Babesia. Blood samples collected from 143 cheetahs at four study sites, namely the Ann van Dyk Cheetah Breeding Center-De Wildt (Brits and Shingwedzi), the Cheetah Outreach and the Hoedspruit Endangered Species Centre, were examined for Babesia infection. The V4 hypervariable region of 18S rRNA gene was amplified and subjected to the Reverse Line Blot (RLB) hybridisation assay. Hybridisation of the parasite DNA with Babesia genus and species-specific probes was evident. The results showed a predominance of Babesia lengau (n=63, 44.1%), followed by Babesia felis (n=3, 2.1%) and Babesia canis rossi (n=7, 4.8%). Unfed ixodid ticks (n=10,432), collected from the vegetation by drag-sampling, represented five species: Amblyomma hebraeum, Amblyomma marmoreum, Haemaphysalis elliptica, Rhipicephalus (Boophilus) decoloratus, Rhipicephalus simus and Rhipicephalus zambeziensis,. The monthly occurrence of ixodid ticks at the De Wildt Cheetah Breeding Centre (Brits) showed a higher activity in the warm months of the year. Recovery of ticks decreased during the warm hours of the day, suggesting that free-living ticks are humid dependent. The presence of birds, rodents, free-ranging antelopes such as nyalas (Tragelaphus angasii), kudus (Tragelaphus strepsiceros), bushbucks (Tragelaphus scriptus) and impalas (Aepyceros melampus), as well as Burchell’s zebras (Equus burchellii) and leopard tortoises (Geochelone pardalis) can contribute to the availability of various tick species at the breeding centres. Mice as the host for immature instars of ixodid tick species and unfed ixodid ticks were studied for presence of Babesia species. Babesia lengau was detected in 22 (39.2%) mice as well as in Haemaphysalis elliptica larvae, nymphs and adults. The presence of B. lengau in mice suggests a long-term association since the host preference of B. lengau for mice remains unclear. However, the presence of this parasite in unfed imature and adult H. elliptica is indicative of a transstadial transmission suggesting that this tick species may be a potential vector for B. lengau. The correlation between Babesia infection and various parameters such as gender, age, tick burdens and location, in two different breeding farms belonging to the De Wildt Cheetah Breeding Centre was analysed using the Fisher’s exact test analysis. The prevalence of Babesia species in cheetahs was associated with tick burden suggesting a strong positive correlation between the prevalence of infection and presence of suspected vector ticks. Regardless of tick burden, age could be related to prevalence of infection, meaning that the fact that older cheetahs had a higher prevalence of infection with Babesia species. These findings were of considerable interest especially since at the time of study the cheetahs in both populations did not show clinical signs of infection with Babesia species.
