| Abstract: | The protein and antigenic composition of adult and larval stages of Ancylostoma ceylanicum, a human hookworm maintained in golden hamsters (Mesocricetus auratus), was studied employing immunochemical techniques. SDS-polyacrylamide gel electrophoresis revealed the presence of 47 and 43 protein bands in adult worms and infective larvae respectively in the molecular weight range of 10-170 kD. Crossed immunoelectrophoretic analysis, using immune rabbit sera, showed the presence of 32 antigenic peaks in adults and 19 in infective larval stage. Most of the antigens were common between adult and larval stage as evidenced by cross-line immunoelectrophoresis, although some stage specific antigens were also identified. These studies also demonstrate the complex nature of adult worms as compared to larvae. |
