Abstract

BRAGA, Fabio Ribeiro et al. Destruction of Strongyloides venezuelensis infective larvae by fungi Duddingtonia flagrans, Arthrobotrys robusta and Monacrosporium sinense. Rev. Soc. Bras. Med. Trop. [online]. 2011, vol.44, n.3, pp. 389-391. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822011000300026.

INTRODUCTION: Strongyloides venezuelensis has been used as a model for studying human strongyloidosis. METHODS: This study aimed to compare the ability of predatory nematophagous fungi Duddingtonia flagrans (AC001), Arthrobotrys robusta (I-31) and Monacrosporium sinense (SF53) and on infective larvae (L3) of Strongyloides venezuelensis in laboratory conditions on 2% water-agar medium. RESULTS: At the end of the experiment, the percentage reductions of Strongyloides venezuelensi L3 were: 93% (AC001), 77.2% (I-31) and 65.2% (SF53). CONCLUSIONS: The nematophagous fungi were able to capture and destroy the L3 in vitro and can be used as biological controllers of Strongyloides venezuelensi.
