Cytotoxic activities of some Pseudomonas aeruginosa isolates: Possible mechanisms and approaches for inhibition

The cytotoxicity of 6 highly cytotoxic Pseudomonas aeruginosa isolates was tested against Vero cells. Cytotoxicity was found to be cell-associated, high cytotoxicity was observed at a multiplicity of infection of 200:1, and this activity gradually decreased as the bacterial count decreased.
