A total of 180 sera consisting of 50 sera from Kenyans with surgically confirmed hydatidosis and 130 sera from individuals without hydatid disease were examined. "Antigen 880" (which is suspected to be similar to Antigen B) showed a sensitivity of 88%. No false reactions were obtained with sera from individuals with non-hydatid infections, hence a specificity of 100% was recorded with this antigen. "Antigen 346" (which is similar to Capron's "Arc 5") showed a sensitivity of 52% and a specificity of 100%. It is concluded that "Antigen 880" may be more useful than "Arc 5" in the diagnosis of human hydatidosis in Kenya due to the high sensitivity obtained with the antigen.
