One isolate of predator fungi Duddingtonia flagrans (AC001) was assessed in vitro regarding the capacity of supporting the passage through pigs' gastrointestinal tract without loss of the ability of preying infective larvae Oesophagostomum spp. Fungal isolates survived the passage and were efficient in preying L(3) since the first 8 h of collection (p < 0.01) in relation to the control group (without fungus). Compared with control, there was a significant decrease (p < 0.01) of 59.6% (8 h), 71.7% (12 h), 76.8% (24 h), 81.0% (36 h), 78.0% (48 h), 76.1% (72 h), and 82.7% (96 h) in means of infective larvae Oesophagostomum spp. recovered from treatments with isolate AC001. Linear regression coefficients of L(3) of recovered Oesophagostomum spp. regarding the collections due to time were -0.621 for control, -1.40 for AC001, and -2.64 for NF34. Fungi D. flagrans (AC001) had demonstrated to be promising for use in the biological control of pig parasite Oesophagostomum spp.
对捕食性真菌弗氏达丁顿菌（AC001）的一个分离株进行了体外评估，以确定其支持在猪胃肠道中通过而不丧失捕食食道口线虫属感染性幼虫能力的情况。真菌分离株在通过胃肠道后存活下来，并且自收集后的最初8小时起（p < 0.01）就能够有效捕食第三期幼虫，相对于对照组（无真菌）而言。与对照组相比，用分离株AC001处理后回收的食道口线虫属感染性幼虫数量显著减少（p < 0.01），分别减少了59.6%（8小时）、71.7%（12小时）、76.8%（24小时）、81.0%（36小时）、78.0%（48小时）、76.1%（72小时）和82.7%（96小时）。回收的食道口线虫属第三期幼虫数量关于收集时间的线性回归系数，对照组为-0.621，AC001为-1.40，NF34为-2.64。弗氏达丁顿菌（AC001）已证明在猪寄生虫食道口线虫属的生物防治中具有应用前景。
