| are clinical isolates of pseudomonas aeruginosa more virulent than hospital environmental isolates in amebal co-culture test? | pseudomonas aeruginosa is an important opportunistic pathogen in hospital-acquired infections. as an environmental bacterium, it colonizes soil and water as well as hospital water supply and shares its natural habitat with free-living amebae. it has been shown previously that an ameba host system can be used to analyze the virulence of p. aeruginosa strains. in this study we have developed a simple amebal co-culture test with acanthamoeba polyphaga to compare the virulence of p. aeruginosa betwe ... | 2006 | 16505663 |
