Intracellular bacteria of Acanthamoebae resembling Legionella spp. turned out to be Cytophaga sp.
Acanthamoeba sp. isolated from the drinking water system of a hospital harboured gram-negative bacteria multiplying inside phagosomes and within the cytoplasm of their host cells. According to their morphology demonstrated by electron microscopy they resembled Llaps (Legionella-like amoebal pathogens) but turned out to be Cytophaga sp. as shown by a typical profile of cellular fatty acids obtained by means of gas-liquid chromatography.
