Babesia divergens vaccine

ABSTRACT

A vaccine strategy against Babesia divergens bovine babesiosis was sucessfully developed after perfecting of an efficient in vitro culture. Crude supernatants and purified fractions were able to induce a vaccine protection in gerbils against B. divergens infection. More, supernatants induced an effective vaccine protection in cattle. The role of B. divergens exoantigens of 17, 37, 46, 70 and 90 kDa in the development of the immune response was cleary demonstrated in gerbils, cattle, and man.
