Evaluation of adult schistosoma mansoni in cercarial antigens in serodiagnosis and schistosomiasis using IHAT and ELISA

ABSTRACT

Examination of 200 bilharzial cases divided into four groups and 50 normal controls to evaluate the efficiency of adult Schistosoma mansoni and cercarial antigens in serodiagnosis of schistosomiasis using IHAT and ELISA revealed that IHA test showed high sensitivity that decreased with the progress of clinical status of the disease if adult worm antigen was utilized. Also, IHAT adult antigen was more sensitive for serodiagnosis than with cercarial antigen, while ELISA is less sensitive using both cercarial and adult antigens
