Title New Legionella Species Has Been Identified
Introduction Legionella clemsonensis recently discovered through whole genome sequencing.

Cinnaminson, NJ, October 24th, 2016  

Recently, students at Clemson University identified a new species of the bacteria Legionella, named Legionella clemsonensis. The Centers for Disease Control and Prevention (CDC) worked with the students to identify the species that originated from a patient in Ohio. According to the CDC, Legionella clemsonensis was analyzed by whole genome sequencing and declared not to be Legionella pneumophila, the most common pathogen in the group. Another differing factor was that when the strain of bacteria was hit with ultraviolent light, it fluoresced green, unlike other Legionella strains that fluoresce blue, red or yellow.

Legionella is a type of bacteria that is commonly found in the biofilm of water, occurring naturally in the environment or in manmade environments. Past outbreaks have been associated with cooling towers, hot tubs, hot water tanks, plumbing systems and decorative fountains. When aerosolized water containing Legionella is inhaled or aspirated, it can cause a form of pneumonia known as Legionnaires’ disease.

“It is wonderful news that by using 21st century technology such as whole genome sequencing, we can now identify new species more rapidly than relying on older technologies such as biochemical testing or Pulsed Field Gel Electrophoresis which lack the discriminatory power,” said Diane Miskowski, MPH, National Legionella Program Manager at EMSL Analytical, Inc.

EMSL Analytical, Inc. offers Legionella testing services and sampling supplies at its 15 CDC ELITE certified Legionella laboratories throughout North America. EMSL has also earned New York State Department of Health Environmental Laboratory Accreditation Program (NYSDOH ELAP) certification for Legionella testing at four of their laboratory locations. In addition their lab in Cinnaminson, New Jersey offers whole genome sequencing as well as sequence-based typing to further discriminate between Legionella species and strains.
