EMSL Analytical offers rapid PCR and traditional culturing methods to identify Legionella, the microbial pathogen that causes Legionnaires’ disease and Pontiac fever.

A Portland apartment complex for senior citizens recently experienced an outbreak of Legionnaires’ disease after Legionella bacteria was found in the building’s water system. The outbreak led to one fatality, four hospitalized residents and more than 100 residents being urged to leave the apartment complex. This concern came to light after several senior residents contracted pneumonia.

Legionella is found naturally in the environment but can proliferate rapidly upon entering many man-made environments. This includes cooling towers, potable water systems, hot tubs, hot water tanks, large plumbing systems and decorative fountains. In this case, the bacteria was found in the potable water system of the apartment complex and the contaminated water droplets were inhaled, which caused the outbreak of Legionnaires’ disease in some residents.

“People 55 and older, and those with chronic lung disease or weakened immune systems are at increased risk of developing Legionnaires’ disease, which the CDC states can be fatal in about 10% of the cases,” said Joseph Frasca, Senior Vice President of Marketing at EMSL Analytical, Inc. “It’s important for apartment complexes, universities and other buildings to actively maintain their water systems and test them regularly for Legionella. Taking proactive measures to test these man-made water systems, as part of an organized water management program to detect Legionella exposure risks, can limit illnesses, outbreaks and fatalities. If an outbreak has already occurred, testing can be instrumental for identifying the source of the bacteria before more cases of Legionnaires’ disease are contracted.”

EMSL Analytical, Inc., with testing laboratories across the United States and Canada, offers traditional culturing methods, rapid quantitative PCR and Whole Genome Sequencing (WGS) test methods to identify Legionella from all types of environmental samples. All 20 of our Legionella laboratories have received the CDC’s Certificate of Proficiency from its ELITE Program for Legionella testing and another five locations are NYSDOH ELAP Legionella certified laboratories.
