Isolation of Corynebacterium pseudotuberculosis from the cervical canal of clinically normal sows.

ABSTRACT

Two isolates from the cervical canal of clinically normal sows were indistinguishable from Corynebacterium pseudotuberculosis in their biochemical properties and genetic homology by DNA-DNA hybridisation. Furthermore, three sheep inoculated with one of the isolates developed typical lesions of caseous lymphadenitis and gave antibody responses specifically to C pseudotuberculosis.
