IgG (left panel) and IgA (right panel) response to Cryptosporidium parvum crude soluble antigen as seen by ELISA. Test sera were collected from HIV seropositive Cryptosporidium positive (Gp I), HIV seropositive Cryptosporidium negative (Gp II), HIV seronegative Cryptosporidium positive (Gp III), HIV seronegative Cryptosporidium negative apparently healthy (Gp IV) and HIV seronegative Cryptosporidium negative subjects infected with other parasites (Gp V).
