چکیده انگلیسی
Acanthamoeba is a genus of free-living amoebae found to be able to host many bacterial species living in the environment. Acanthamoebae and Vibrio cholerae are found in the aquatic environments of cholera endemic areas. Previously it has been shown that V. cholerae O1 and O139 can survive and grow in Acanthamoeba castellanii. The aim of this study was to examine the ability of Acanthamoeba polyphaga to host V. cholerae O1 and O139. The interaction between A. polyphaga and V. cholerae strains was studied by means of viable amoeba cell counts and viable count of the bacteria in the absence and presence of amoebae. The viable count of intracellularly growing bacteria was estimated by utilizing gentamicin assay. Electron microscopy was used to determine the localization of V. cholerae inside A. polyphaga. The results showed that A. polyphaga enhanced growth and survival of V. cholerae, which grew and survived inside the amoeba cells for 2Â weeks. The electron microscopy showed that A. polyphaga hosted intracellular V. cholerae localized in the vacuoles of amoeba cell. Neither the presence of V. cholerae together with A. polyphaga nor the intracellular localization of the bacteria inhibited growth and survival of A. polyphaga. The outcome of the interaction between these microorganisms may support strongly the role of A. polyphaga as host for V. cholerae O1 and O139.
