| Abstract: | Natural antibodies to 65 kD heat shock protein (hsp65) of Mycobacterium bovis were found in the sera of Lewis rats. The levels of these natural hsp65 antibodies differed substantially between the individual rats. Each rat was subsequently tested for its susceptibility to develop arthritis following injection of M. tuberculosis in incomplete Freund adjuvant. It was found that the incidence and severity of the induced arthritis did not differ between groups of Lewis rats with relatively high and relatively low natural antibody levels to hsp65. Inoculation of rats without natural antibodies to hsp65 with intestinal contents did not induce hsp65 antibodies, although the rats were able to respond to the antigen. |
