An improved Theileria parva DNA detection assay based on the polymerase chain reaction (PCR) using primers derived from the 104 kDa antigen (p104) gene was developed to detect parasite DNA in blood spots on filter paper. The specificity of the assay was validated using DNA from a wide range of ca...

Vaccines based on recombinant Bm86 gut antigen from Boophilus microplus are a useful component of integrated control strategies against B. microplus infestations of cattle. The capacity of such vaccines to control heterologous infestations by two African tick species was investigated. The mean we...

The transcriptional control of gene expression is not well documented in the Arthropoda. We describe transcriptional analysis of two exceptionally divergent homologues (Ra86) of the Bm86 gut antigen from Rhipicephalus appendiculatus. Bm86 forms the basis of a commercial vaccine for the control of...

Mycoplasma species are responsible for several economically significant livestock diseases for which there is a need for new and improved vaccines. Most of the existing mycoplasma vaccines are attenuated strains that have been empirically obtained by serial passages or by chemical mutagenesis. Th...

A double bounded contingent valuation (CV) model was used to assess the Willingness to Pay (WTP) for vaccination of cattle against RVF in a sample of 276 livestock producers in Murang’a, Laikipia and Kwale Counties. While the level of awareness about the disease was rather low, nearly all respond...

Tick-borne diseases (TBDs) are a major economic constraint to livestock production in sub-Saharan Africa. ILRI is focussing on developing a range of products, such as vaccines, diagnostics and decision support services to underpin improved control programmes against these diseases. We have develo...

This review of the prospects for developing an immunization procedure against trypanosomiasis explores a number of promising avenues of research. Part I covers variable antigen types (VATs); metacyclic antigens; in vivo and in vitro attenuation; and molecular and genetic engineering. Part II, to ...

Although such vaccines can be effective, for most hemoparasites the mechanisms of acuquired resistance to challenge infection with heterologous par...

T cell responses play an important role in immunity to parasites and other microbial agents of infectious diseases, therefore a number of T cell-directed vaccines are in development. Computer-driven algorithms that facilitate the discovery of T cell epitopes from protein and genome sequences are ...
