Feline leukemia virus. Immunization and prevention.
Our understanding of the pathogenesis of FeLV infection is little changed from what was described by Hardy and his colleagues in the mid-1970s. The prevention of FeLV infection consists, first, of avoiding the agent and, second, of providing optimum immunologic resistance. In multi-cat environments, the former is achieved through test-and-removal methods perennially reviewed in the literature and by minimizing exposure to outdoor cats. The latter is possible by attempting to maintain a low-stress, pathogen-free household and by the use of appropriate, effective immunization programs. Simple immunologic concepts used for the development of vaccines against feline distemper and rabies have evolved to enable generation of products that can now protect against retroviruses. The use of more complex biologic methods, such as recombinant technology and the manipulation of antigen presentation, bears encouragement, so that perhaps one day the most destructive of feline infectious diseases may be checked.
