Certain bacteria are capable of migrating along fungal hyphae, using them as a dispersal mechanism to cross otherwise-prohibitory distances. Three strains of fungal-migratory Paraburkholderia were isolated from the mycelium of wood-decay fungi, and inoculated onto ten strains of wood-decay fungi growing on solid agar medium. Two of the three bacteria were able to migrate along the hyphae of all fungi, although to differing extents. No bacteria-associated growth inhibition was observed with eight of the ten fungi, but mycelial extension rate of two strains of Phanerochaete was significantly reduced. Bacteria were also introduced into fungus-fungus competitive pairings, and significantly reduced the competitive performance of one of the Phanerochaete strains. Additionally, in several cases, introducing bacteria into competitive interactions made the outcome unpredictable, whereas in the absence of bacteria one fungus was consistently dominant. This is the first time that bacteria have been shown to influence fungal inter-specific competition.

某些细菌能够沿着真菌菌丝迁移，并将它们作为扩散机制穿越其他禁止的距离。从木腐烂真菌的菌丝体中分离出三株真菌迁移性巴拉伯霍尔德菌，并接种到在固体琼脂培养基上生长的十株木腐烂真菌上。三种细菌中的两种能够沿着所有真菌的菌丝迁移，尽管程度不同。十种真菌中有八种没有观察到与细菌​​相关的生长抑制，但是两株Phanerochaete菌丝体的菌丝扩展率却明显降低。细菌也被引入到真菌-真菌竞争配对中，并大大降低了Phanerochaete之一的竞争表现。株。另外，在某些情况下，将细菌引入竞争性相互作用会使结果无法预测，而在没有细菌的情况下，一种真菌始终占主导地位。这是细菌首次被证明能影响真菌的种间竞争。
