A new innovative method, MICA Legionella, allows for the automatic enumeration of Legionella pneumophila in domestic water samples in 2 days, with a detection limit of 2 CFU per test portion. Here we show that it gives equivalent results to those obtained by the French standard method NF T90-431 in 7 to 15 days.

Background: Frequent testing for Legionella concentration in water is required by most health risk monitoring organizations worldwide. Domestic hot water and cooling tower water networks must be regularly controlled to prevent Legionnaires' disease, a potentially deadly lung infection. MICA Legionella is the fastest culture-based detection method for all serogroups of Legionella pneumophila, with automatic enumeration in 48 h and no need for confirmation.

Pathogenic bacteria secrete a variety of proteins that manipulate host cell function by targeting components of the plasma membrane, cytosol, or organelles. In the last decade, several studies identified bacterial factors acting within the nucleus on gene expression or other nuclear processes, which has led to the emergence of a new family of effectors called "nucleomodulins". In human and animal pathogens, for Gram-positive bacteria and , , , and for Gram-negative bacteria, have led to pioneering discoveries.
