Detection of Strongyloides stercoralis in Tierralta, Colombia using four parasitological methods
Artículo de revista
Introduction: soil-borne helminth Strongyloides stercoralis is one of the most neglected among neglected tropical diseases. A study was conducted of the presence of S. stercoralis in a village from the department of Córdoba, Colombia, with the purpose of comparing the effectiveness of several diagnostic methods. Methods: stool samples from 262 persons were evaluated. Each sample was examined with four parasitological techniques: direct examination, agar plate culture (APC), the modified Baermann method, and the Harada-Mori technique. Results: S. stercoralis was detected by at least one of the techniques in four of the 262 samples: the Harada-Mori technique detected 2 cases, APC 1 case and direct examination 1 case. The modified Baermann method did not detect any case. No significant differences were found when comparing the techniques. Conclusions: results show that S. stercoralis is not endemic in the village of Córdoba, and that parasitological techniques should be used in combination to improve the quality of diagnosis.
