Interpretive Summary: A high percentage of lions in Africa are infected with bovine tuberculosis and many of these lions are co-infected with an immunodeficiency virus. Prior to testing in lions, domestic cats were used as a feline model to test the immunogenicity and safety of a candidate vaccine. Four cats infected with feline immunodeficiency virus and four non-infected cats were vaccinated with an attenuated live tuberculosis vaccine. Adverse reactions were not detected and all cats had an immune response to the vaccine, although a lower response was detected for immunodeficiency infected cats. These findings demonstrate the potential for use of an attenuated live tuberculosis vaccine in lions.

Technical Abstract: Feline immunodeficiency virus (FIV)+ and FIV- cats (n = 4/group) received 2 x 10**6 cfu Mycobacterium tuberculosis Delta-lysA Delta-panCD intramuscularly. Vaccination elicited antibody responses; albeit, at lower levels in FIV+ cats as compared to FIV- cats. Delayed-type hypersensitivity responses were minimal in both groups. No adverse reactions were found.
