Fig. 7. Phagocytosis of different particles by lvsA and lvsB mutant cells. Cells were incubated for 1 hour with the indicated particles. The amount of internalized fluorescence was determined by FACS. The results are expressed as a percentage of the internalization by wild-type cells in the same experiment. The indicated values are the mean and standard deviation of seven independent experiments. Beads, latex beads, K.a., Klebsiella aerogenes, E. coli, Escherichia coli, P.a., Pneumophila aeruginosa, S.b., Streptococcus bovis.
