The effect ofAeromonasstrains on the growth ofLegionella

摘要

Thirty‐one environmental and two type strains ofAeromonaswere tested for their ability to inhibit the growth of strains of severalLegionellaspecies. Of 10Legionellaspp. tested, onlyLegionella pneumophilaandLeg. longbeachaewere able to resist the inhibitory effects of some of theAeromonasstrains. SelectedAeromonasstrains were also tested for their ability to inhibit the growth of several non‐legionella strains. None of the non‐legionella strains were inhibited by any of the selectedAeromonasstrains. Attempts were made to isolateAeromonasstrains from cooling towers andAeromonas hydrophilawas isolated from one of the cooling towers tested. The results suggest that many strains ofAeromonascan inhibit the growth ofLegionellastrains on solid media and could affect the isolation of legionellas from water so
