Abstract

Tick experimentally infested calves and vaccinated with TCRPV. by the time of infestation, 7 days post infestation or 21 days after infestation responded normally to vaccination. The level of the serum rinderpest neutralizing antibody titres acquired through vaccination was identical to that detected in non infested vaccinated animals, These results were obtained regardless the degree of tick infestation mild, moderate, or heavy. Field cattle harbouring Babesia, Theileria or Anaplasma responded to vaccination with the tissue culture rinderpest vaccine as non harbouring animals and serum rinderpest neutralizing antibody titres were identical and this regards to the choronicity of these blood parasites in Egypt.
