Abstract Background Conventional diagnostic methods for human being ascariasis are based on the detection of eggs in stool samples. However, studies of ascariasis in pigs have shown the prevalence and the number of eggs recognized in the stool do not correlate well with exposure of the MKT 077 herd to the parasite. On the other hand, an ELISA test measuring antibodies to haemoglobin (AsHb) offers been shown to be useful for estimating transmission intensity on pig farms. In this study, we further characterized the AsHb antigen and screened samples from a population-based study conducted in an area that is endemic for in Indonesia to assess changes in AsHb antibody rates and levels in humans following mass drug administration (MDA). Strategy/Principal findings We developed and evaluated an ELISA to detect human being IgG4 antibodies to AsHb. We tested 1066 plasma samples collected at different times from 599 subjects who lived inside a town in rural Indonesia that was highly endemic for ascariasis. The community received 6 rounds of MDA for lymphatic filariasis with albendazole plus diethylcarbamazine between 2002 and 2007. While the AsHb antibody assay was not sensitive for detecting all individuals with eggs in their stools, the percentage of seropositive individuals decreased rapidly following MDA. Reductions in antibody rates reflected decreased mean egg output per person both at the community level and in different age groups. Two years after the last round of MDA MKT 077 the community egg output and antibody prevalence rate were reduced by 81.6% and 78.9% respectively compared to baseline levels. Summary/Significance IgG4 antibody levels to AsHb appear to reflect recent exposure to transmission intensity in areas that can be used to assess the effect of control steps on the pressure of transmission. Author Summary Ascariasis is definitely a neglected tropical disease caused by the intestinal nematode that affects hundreds of millions of people in the developing world. Current methods for diagnosis of this infection are based on detecting eggs.
