Heritability of susceptibility to infection with Theileria parva was estimated from full sib families of Rhipicephalus appendiculatus ticks. Male and female ticks of 2 stocks were mated singly. Nineteen full sib families of the Mugufa stock and 17 full sib families of the Kiambu stock were obtain...
A comparison of ten methods for staining tick salivary glands for detection of Theileria parva infection from ticks fed on rabbits for various periods was under taken. Staining with azure without hydrochloric acid hydrolysis was found to be the most reliable method for detection of the presporozo...
Among the blood-sucking arthropods, ixodid ticks have some of the most complicated feeding behavior requirements. Feeding is preceded by an attachment process, and each instar has to remain fully attached to the same feeding site for a period of 2-14 days. These biological demands have for a long...
The transmission of Theileria parva by nymphal and adult Rhipicephalus appendiculatus was compared by the assessment of salivary gland infections in tick batches fed on the same group of infected cattle at the same time. When larval and nymphal R. appendiculatus Muguga ticks were fed concurrently...
A large database on the transmission of a stabilate of the Theileria parva Muguga stock from one breed of cattle using two stocks of Rhipicephalus appendiculatus, Muguga and O1 Pejeta was developed and analysed. Factors associated with the ticks and cattle, and the infections developing in cattle...
The initiation of feeding of infected Rhipicephalus appendiculatus adults induces the rapid development of Theileria parva sporoblasts within the salivary gland acini leading to the production of numerous sporozoites which are inoculated into the mammalian host initiating infection. In this study...
