A Salmonella abortusovis inactivated vaccine protects mice from abortion after challenge.

Two types of Salmonella abortusovis vaccines were prepared, one with aluminium hydroxide (vaccine A) and the other with water in oil (vaccine B) adjuvants. They were compared in a pregnant mouse model, aiming at protecting them from abortions after challenge with a virulent strain of S. abortusovis.

Preparation of a high titre Salmonella abortusovis H-antigen and antiserum and improvement of the microagglutination test.

Serological diagnosis of small ruminant abortions due to Salmonella abortusovis (S.a.o) was improved by using modified procedures to produce high titre H-antigens and anti-H serum.
