Human strongyloidiasis is an important helminth infection and until recently has not been included in large-scale control interventions, in part to the lack of appropriate field-based diagnostics. It has also come to light that current PCR-based diagnostics conflate Strongyloides stercoralis and S. fuelleborni. The latter species is normally found in non-human primates and can infect man. Currently, there is a knowledge gap concerning the levels of co-infection of these species in routine diagnostics in the UK as well as in Europe. Their overlap in endemic areas of Uganda and Malawi, involving non-human primates is also under investigated. This project will build upon an exiting IAA award which is developing better TaqMan assays to detect and differentiate these helminths. It will also link with the USA Diagnostic Company, IVD Research, Inc. & SafePath Laboratories, LLC which supply ELISA kits for serological diagnosis of strongyloidiasis. The intention of this project is to apply these new DNA assays in endemic areas of strongyloidiasis e.g. Uganda and Malawi, screening human and non-human primate populations, developing a suitable POC assay based upon RPA technology. The methods will be compared against standard serological diagnostic methods. |
