[Nature and specificity of the auxilliary rabbit test in the diagnosis of swine fever].

Experiments were carried out with the aim to reveal the causes for the inhibited temperature reaction in rabbits to swine pest virus strain K in case of previous injection with virulent pest virus. It was established that in the serum of rabbits injected with virulent swine pest virus specific antibodies are found, which are capable to neutralize the lappinized K virus introduced later. This phenomenon which is specific enough and highly sensitive can be used with success as an auxiliary biological test in classical swine pest diagnosis.
