'STUDIES ON CROSS-REACTIONS AMONG MYCOBACIERIUM PARATUBERCULOSIS, MYCOBACTERIUM PHLEI AND CORYNEBACTERWM REN ALE BY AGAR GEL IMMUNODIFFUSION TEST AND COUNTER IMMUNO ELECTROPHORESIS

摘要

The sonicated antigens of Mycobacterium paratuberculosis. Mycobacterium phlei and Corynebacterium renale were analysed for cross-reactions by Agar Gel Immunodiffusion (AGID) test and Counter Immuno Electrophoresis(CIE). In AGID, cross-reaction was evident and the extent of antigenic sharing was difficult to spell out clearly. Further analysis by using antisera of M. paratuberculosis with antigens of M. phlei and C. renale in CIE showed 4 and 1 cross-reacting antigens respectively. At the same time when antisera of M. phlei was used against M. paratuberculosis and C. renale sonicates, there were 6 and 2 cross-reacting antigens respectively.
