The potential relationships between SPFs and MIFs remain uncharacterized," scientists writing in the Journal of Bacteriology report. "Previously we determined that L. pneumophila survives, but does not replicate, while it transiently resides (for 1 to 2 h) in food vacuoles of the freshwater ciliate Tetrahymena tropicalis before being expelled as legionellae-laden pellets.
