Summary To assess the role of bacteria in pine wilt disease ( PWD ), aseptic M form (with a mucronated tail) and R round B ursaphelenchus xylophilus . mucronatus were obtained compared, terms reproduction pathogenicity, with non‐aseptic nematode. In addition, isolated from nematodes trees inoculated identified. The results indicated that associated significantly lowered Both forms induced death all infected 7‐ to 8‐year‐old trees, while caused almost no plant mortality. High numbers distributed throughout lower number their distribution stems limited within inoculation site. Bacteria not recovered these same kinds nematodes. Two species both icrobacterium trichotecenolyticum was common control trees. These suggest is causal agent cannot increase virulence
