苯乙酸 (PA) 是一种由松材线虫 (Bursaphelenchus xylophilus) 伴随的三种细菌菌株产生的毒素，被发现在线虫的培养物中形成。动物营养物、营养肉汤 (NB) 培养基比植物营养物、马铃薯蔗糖麦芽提取物 (PSM) 培养基更适合伴随细菌产生 PA。推测 PSM 培养基中死亡的线虫为细菌提供了在强毒株OKD-3的培养物中，比弱毒株OKD-1检测到更多的PA，伴生细菌的PA产量可以主导线虫的致病性。
Phenylacetic acid (PA), a toxin produced by three strains of bacteria accompanying the pine wood nematode, Bursaphelenchus xylophilus, was found to be formed in a culture of the nematode, An animal nutrient, nutrient broth (NB) medium, was more suitable for PA production of the accompanying bacteria than a vegetable nutrient, potato sucrose malt extract (PSM) medium, It is presumed that dead nematodes in the PSM medium provided the bacteria with nutrient for PA production, In the culture of virulent isolate OKD-3, more PA was detected than in that of less-virulent isolate OKD-1, PA production of the accompanying bacteria can dominate the pathogenicity of the nematode.
