The humoral response in hamsters following vaccination against Ancylostoma ceylanicum infections with DNA construct was investigated. Groups of hamsters were injected intramuscularly with plasmid pcDNA 3.1, containing cDNA of ACEY-1 cysteine proteinase. Vaccination resulted in IgG antibody response to somatic extracts of adult A. ceylanicum. The highest level of antibodies was observed seven weeks after vaccination.
