Importance of type II secretion for survival of Legionella pneumophila in tap water and in amoebae at low temperatures.

Maria A Söderberg1, Jenny Dao, Shawn R Starkenburg, Nicholas P Cianciotto.   

Abstract

Legionella pneumophila type II secretion mutants showed reduced survival in both tap water at 4 to 17 degrees C and aquatic amoebae at 22 to 25 degrees 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.
