Two recombinant vaccines against Theileria parva, based on a near full-length version of the sporozoite surface antigen p67 (p67635), or an 80 amino acid C-terminal section (p67C), were evaluated by exposure of immunized cattle to natural tick challenge in two sites at the Kenya Coast and one i...

Bovine babesiosis has been identified clinically in many areas of Morocco. A seroepidemiological survey of B. bigemina infection was conducted in the 5 main dairy cattle areas in order to estimate the prevalence of the infection. A total of 1819 bovine sera was tested using ELISA to identify ani...

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...

Rhipicephalus appendiculatus adult ticks, collected int he field from zebu (Bos indicus) and exotic (Bos tarus) cattle with high antibody titres to Theileria parva schizont antigen, transmitted Theileria parva infection typical of East Coast fever to susceptible cattle. Uninfected R. appendiculat...

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...
