Figure 3: Viability of A. spelaea (106 cells/ml) following 72h incubation with different bacterial strains (107 CFU⁄ml). Results illustratepercentage survival relative to control (absence of bacteria) amoebal counts. Abbreviations; A. hydrophila: Aeromonas hydrophila, Ps.aeruginosa: Pseudomonas aeruginosa, C. cloacae: Citrobacter cloacae, E. aerogenes: Enterobacter aerogenes, E. coli 1: Escherichia coli 1, Kl.pneumoniae: Klebsiella pneumoniae, MRSA: Methicillin-resistant Staph. aureus, P mirabilis: Proteus mirabilis, R. ornitholytica: Raoultellaornitholytica, R. terrigena: Raoultella terrigena. Mean value of three replicate experiments are shown. The values of error bars were too smallto be presented
