title: Genetical and electron microscopical studies on Cryptosporidia.
abstract: The present work was to clarify whether C. parvum oocysts have different strains in human patients by using different staining, electron microscopical and genetical techniques. A trial to induce a vaccine against Cryptosporidial infection in mice was carried out using killed autoclaved Cryptosporidial oocysts. The results obtained were satisfactory. Two genotypes of C. parvum, viz: human and zoonotic genotypes were detected and described. The killed vaccine used orally gave a promising results.
