[Antigenic and allergenic properties of various atypical Mycobacteria and Mycobacterium avium. I. Immunoelectrophoretic analysis of antigens in water extracts].
4 strains of acid-resistant bacilli were examined: M. kansasi, scotochromogenic bacilli of Nicolas strain, M. fortuitum and M. avium D4. Water extracts prepared from these strains according to Whiteside and Baker method were used as antigens in the immunoelectrophoresis reaction and were also used to obtain specific serums on rabbits which were hyperimmunized according to Tuboly's method. In the immunoelectrophoresis reaction water extracts were examined against nonsaturated serums, as well as cross-saturated extracts of the investigated bacilli. It was found that M. kansasi and M. avium possessed 9 antigen components each and bacilli of scotochromogenic strain Nicolas and M. fortuitum 5 each. The degree of antigen relationship between the examined bacilli was expressed with 1-4 common antigen components.
