ABSTRACT
Enzyme-linked immunosorbent assay (ELISA) was carried out in Gimvi village, India, using antigens derived from S. haematobium and S. mansoni adult worms. Patients excreting schistosome ova in urine elicited positive ELISA titres, whereas patients who were previously positive but are no longer passing viable eggs were negative for ELISA.

A modified Rieckmann test was developed for assessing chloroquine sensitivity of Plasmodium vivax strains. This test envisages the evaluation of parasite growth with different concentrations of the drug and its comparison with controls, at the end of a 48-hour experimental period. Using this test, 16 strains were assessed for their chloroquine sensitivity. Twelve strains were found to be sensitive, and 4 were resistant to chloroquine.
