Modified Formalin-Ether Concentration Technique for Diagnosis of Human Strongyloidiasis Witthaya Anamnart, Pewpan M. Intapan, Wanchai Maleewong Korean J Parasitol 2013;51(6):743-745. Published online December 31, 2013 DOI: https://doi.org/10.3347/kjp.2013.51.6.743 Abstract PDF We compared the efficacy and applicability of a modified formalin-ether concentration technique (M-FECT) to the conventional FECT (C-FECT) and the agar plate culture (APC) method for the detection of Strongyloides stercoralis larvae. For this purpose, we used 600 human fecal specimens collected in an endemic area of southern Thailand. In the M-FECT, we used 2 layers of wire meshes, instead of gauze, to avoid the loss by absorption/adhesion of larvae to the gauze during filtration, and we reduced the exposure time of S. stercoralis larvae in stool samples to formalin. By such simple modifications, the efficacy of M-FECT has become comparable to APC and was much better than that of C-FECT for the diagnosis of strongyloidiasis.
