Legionnaire Disease
Report summarizes legionnaire disease study findings from University of Louisville, Medical Department
March 31st, 2009
"To examine the role of the PmrA/PmrB two-component system (TCS) of Legionella pneumophila in global gene regulation and in intracellular infection, we constructed pmrA and pmrB isogenic mutants by allelic exchange. Genome-wide microarray gene expression analyses of the pmrA and pmrB mutants at both the exponential and the postexponential phases have shown that the PmrA/PmrB TCS has a global effect on the expression of 279 genes classified into nine groups of genes encoding eukaryotic-like proteins, Dot/Icm apparatus and secreted effectors, type II-secreted proteins, regulators of the postexponential phase, stress response genes, flagellar biosynthesis genes, metabolic genes, and genes of...
