15. Significant Development of Biologicals
Fowl typhoid Vaccine: Dr. L.C. Bebora and I together have developed a potent
attenuated vaccine against Salmonella gallinarum infection in poultry. It has
been tested in the laboratory for protection and shown to be better than the
currently used live vaccine. It is awaiting field trials.
Camel Pox vaccine : Studies have been done and a field trial has already been
carried out on a camel herd.
Corynebacterium pseudotuberculosis (caseous lymphadenitis in goats) : Studies on the pathogenesis and epidemiology are ongoing; a vaccine based on local strains is under study.
New Castle Disease Virus: Properties of local strains were studied and candidate vaccine clones identified. These are being processed further. We expect a heatstable vaccine soon (Ongoing programme).
Anthrax vaccine: Here we studied the immunosuppresive effect on Trypanosoma congolense on the vaccination with spore Anthrax vaccine in goats. The results have been reported in a thesis form (1987) and a paper published (1990) .
vi. Leptospirosis in Cattle: We studied seroprevalence of leptospiral serovars in Kenya and later isolated local strains. Vaccine prepared using most
commonly occurring serovars (1983-85).
Canine parvovirus enteritis: Here we recovered and studied the causal viral agent, and developed effective therapy biologics to treat exposed puppies.
