THE ISOLATION OF ACTINOBACILLUS SEMINIS FROM BOVINE SEMEN: A PRELIMINARY REPORT
E. M. VAN TONDER AND T. F. W. BOLTON
A case of bilateral epididymitis in a young Friesland bull is described. Actino-bacillis seminis was isolated from the bull's semen. The organism proved to be identical in microscopical, cultural and biochemical characteristics to strains isolated from rams. Serum from this animal, when subjected to a complement fixation test, yielded a suspicious reaction against an antigen prepared from the isolate of a naturally infected ram with clinical epididymitis. Blood sera from two bulls in the Orange Free State gave positive and suspicious reactions respectively to the same antigen.
