Field collections of ticks from two breeds of cattle in the North Western Transvaal showed the common tick species to be Rhipicephalus appendiculatus, Amblyomma hebraeum, Rhipicephalus evertsi evertsi and Hyalomma marginatum rufipes. The number of these ticks was higher on Simmentaler than on Brahman cattle. Correlation was found between the number of ticks on the cattle and their serum gamma g...

background : small ruminants’ babesiosis caused by babesia ovis, is transmitted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. this study was carried out to to estimate the infection rate of b. ovis in sheep and goats by pcr. we have analysed risk factors that might influence infection of sheep and goats with b...

Ixodid ticks were collected during February of each year from 1983-1992 from bontebok and grey rhebok in the Bontebok National Park, Western Cape Province. When available other mammals as well as ground-nesting birds and leopard tortoises were examined. Eleven tick species were recovered. Rhipicephalus nitens followed by Rhipicephalus glabroscutatum and an Ixodes sp. (near I. pilosus) were the ...

Three cattle, which had been experimentally infected with Theileria parva lawrencei and maintained as carriers of the infection, were each infested simultaneously with clean nymphal Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in ear bags on separate ears. After moulting, the ensuing adult ticks were fed on rabbits for 4 days and their salivary glands were examined for infective ...

An unidentified Babesia sp. which causes a mild disease in cattle was isolated in a splenectomized ox that received pooled blood from field cattle. That this organism is pleomorphic and resembles Babesia occultans makes it difficult to differentiate between these organisms microscopically. Initially, it was suspected that this Babesia could be B. occultans. Several attempts to transmit this par...

The objective of this paper is to describe four cases of human parasitism by Rhipicephalus sanguineus (Latrielle) in Brazil. During an investigation regarding the species of ectoparasites of domestic dogs from the metropolitan region of Recife, Pernambuco state, four dog owners were found to be parasitized by ticks. The ticks were collected from these individuals and their dogs. All the ticks w...

Five or 6 rock dassies (Procavia capensis) were shot at monthly intervals for 13 consecutive months in the Mountain Zebra National Park and processed for arthropod parasite recovery. Ten species of ixodid ticks and 2 flea species were recovered. The seasonal prevalence of the rock dassie ticks, Haemaphysalis hyracophila and Rhipicephalus distinctus, and of the immature stages of Rhipicephalus a...

SALIH, D.A., HASSAN, S.M., EL HUSSEIN, A.M. & JONGEJAN, F. 2004. Preliminary survey of ticks (Acari: Ixodidae) on cattle in northern Sudan. Onderstepoort Journal of Veterinary Research, 71: 319–326 In a cross sectional survey conducted during the period June 2001 to July 2002, the geographical distribution of ticks on cattle in the Sudan was determined. Seventeen locations were surveyed from No...

background: considering the importance of ticks as a main group transmitting pathogen organisms, this study de­signed to recognize immunogenic proteins in different tissues of rhipicephalus ( boophilus ) annulatus tick and to find out if there are common proteins in these tissues. methods: seven cattle were experimentally infested with about 10000 r. annulatus larvae and their humoral im­mune r...
