Improved molecular diagnostic tools for human hookworms

Abstract

Blood-feeding hookworms are parasitic roundworms (i.e., nematodes) of major socioeconomic importance, affecting millions of people worldwide. Despite their impact on human health, little attention has been paid to improving practical methods of diagnosis. The genetic characterization of hookworms and specific diagnosis of their infections are central to elucidating the ecology and epidemiology of these parasites as well as the control of the disease they cause. Traditional coprodiagnostic methods have major limitations. This article summarizes progress in the development of molecular-analytical and -diagnostic tools, and discusses the need to establish practical 'laboratory' and 'field' assays for use in integrated hookworm prevention and control programs.
