INTRODUCTION
Strongyloides stercoralis is a nematode that infects much of the population worldwide.
METHODS
This study aimed to compare the ability of predatory nematophagous fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34) and Arthrobotrys robusta (I-31) on infective larvae (L₃) of Strongyloides stercoralis in laboratory conditions on 2% water-agar.
RESULTS
At the end of the experiment, the percentage reductions in Strongyloides stercoralis L3 were 83.7% (AC001), 75.5% (NF34) and 73.2% (I-31).
CONCLUSIONS
The nematophagous fungi were able to capture and destroy the L3 in vitro and may be used as biological controls of Strongyloides stercoralis.
引言
粪类圆线虫是一种感染全球众多人群的线虫。
方法
本研究旨在比较捕食性食线虫真菌——达丁顿菌（AC001）、奇异单顶孢（NF34）和粗壮节丛孢（I - 31）在实验室条件下于2%水琼脂上对粪类圆线虫感染性幼虫（L₃）的作用能力。
结果
实验结束时，粪类圆线虫L₃的减少百分比分别为83.7%（AC001）、75.5%（NF34）和73.2%（I - 31）。
结论
食线虫真菌能够在体外捕获并破坏L₃，可作为粪类圆线虫的生物防治手段。
