摘要: Acinetobacter baumanii, which may be found in water, is an important emerging hospital-acquired pathogen. Free-living amoebae can recovered from the same water networks, and it has been shown that these protozoa support growth of other bacteria. In this paper, we have studied potential relationships between A. baumanii Acanthamoeba species. Two strains isolated hospital were co-cultivated with trophozoites or supernatants two free-living strains: castellanii culbertsoni. Firstly, presence their induced a major increase growth, compared controls. Secondly, affected only viability culbertsonii, no effect on castellanii. Electron microscopy observations cultures investigating bacterial location showed persistence bacteria within cyst wall even after 60 days incubation. our study, survival could favored by strains. Special attention should consequently paid to systems, promote persistence.
