Abstract

The current serological test for human onchocerciasis relies on IgG4 reactivity against the parasite Ov-16 antigen, with reported sensitivities of only 60-80%. As control programs move from control to elimination, it is imperative to identify novel molecules that could improve the serodiagnosis reliability of this disease. In this study we compared the sensitivity of total IgG against OvMANE1-a chimeric antigen previously identified as a potential biomarker of human onchocerciasis-with that of an Ov-16 antibody test to detect an
