Abstract

Visceral leishmaniasis, a chronic and often fatal disease, is caused by the protozoan parasite Leishmania donovani. Both specific and nonspecific antibodies are produced in the course of the disease, and autoantibodies may be involved in pathogenesis. Tubulin and actin have been found to be associated with L. donovani. To learn whether antiactin and antitubulin antibodies are present in visceral leishmaniasis, we tested sera from 263 infected dogs by enzyme-linked immunosorbent assay for antibodies to the antigens L. donovani, actin, and tubulin. All samples reacted positively with L. donovani, and a high percentage reacted positively with all three antigens. Sera from 202 uninfected dogs were also tested, none reacted with L. donovani antigen, although positive reactions were observed for 8 of the samples with actin or tubulin. It was found that the antibody-antigen reaction occurred at the Fab portion of the immunoglobulin molecule. Competitive enzyme immunoassays showed that the reaction was inhibited if the positive serum was first incubated with L. donovani antigen, actin, or tubulin and then tested by enzyme-linked immunosorbent assay. These results suggest that antiactin and antitubulin antibodies are present in the sera of dogs infected with visceral leishmaniasis.
