![]() Published estimates of the number of people currently infected with Strongyloides stercoralis, the species which causes the vast majority of human strongyloidiasis cases, vary between “30–100 million”, and “at least 370 million”. Strongyloidiasis is a soil-transmitted helminthiasis (STH) and although as such it is included within the neglected tropical diseases (NTDs), it is often overlooked in comparison with other STHs and has therefore sometimes been described as (one of) the most neglected NTDs. stercoralis for molecular genetic/genomic analyses and either analyze them themselves or make them available to others for further analysis. We hope this will benefit and encourage researchers conducting field studies or diagnostics to collect and preserve S. stercoralis are found, we emphasize when and how samples can be preserved, stored and shipped for later analysis. Since in many cases the full analysis is not possible or desired at the place and time where S. ![]() Here we provide a guideline for the isolation, preservation, genotyping at the nuclear 18S rDNA and the mitochondrial cox1 loci, and for whole genome sequencing of single S. stercoralis in the process of their diagnostic work preserve some specimens for molecular analysis. One way of achieving this (with little additional sampling effort) would be that people encountering S. stercoralis populations from around the world. It would therefore be very important to obtain molecular genetic/genomic information about S. As a result, their taxonomic status and the question of whether they differ in their pathogenic potential remains open. Molecular studies also showed that humans carry rather different genotypes of S. stercoralis infections have not been reported in any host other than humans, non-human primates and dogs, other as yet unidentified animal reservoirs cannot be excluded. This suggests a potential for zoonotic transmission of S. stercoralis that also infect humans, in addition to a presumably dog-specific Strongyloides species. ![]() Recent molecular taxonomic studies conducted in Southeast Asia and Australia, showed that dogs can carry the same genotypes of S. Strongyloidiasis is a soil-borne helminthiasis, which, in spite of the up to 370 million people currently estimated to be infected with its causing agent, the nematode Strongyloides stercoralis, is frequently overlooked. ![]()
