Abstract

Legionella pneumophila type II secretion mutants showed reduced survival in both tap water at 4 to 17°C and aquatic amoebae at 22 to 25°C. Wild-type supernatants stimulated the growth of these mutants, indicating that secreted factors promote low-temperature survival. There was a correlation between low-temperature survival and secretion function when 12 additional Legionella species were examined.
