Legionella Clemsonensis Sp. Nov.: A Green Fluorescing ~ A novel Legionella species was identified based on sequencing, cellular fatty acid analysis, biochemical reactions, and biofilm characterization. Strain D5610 was originally isolated from the bronchial wash of a patient in Ohio, USA. The bacteria were gram-negative, rod-shaped, and exhibited green f …
Legionnaires’ Disease Cases at a Large Community Hospital ~ Legionnaires’ disease (LD) is a severe pneumonia with a mortality rate of about 10%. The illness remains largely underdiagnosed with outbreaks occurring with alarming incidence. In this study, we assessed the frequency of Legionnaires’ disease among pneumonia cases treated at a large community hospital over a summer season. We invited all admitted patients diagnosed with pneumonia, able to .
Waterline Online News – across the water industry and beyond ~ FREE ACCESS PAPER – Distribution of Legionella and bacterial community composition among regionally diverse US cooling towers Abstract Cooling towers (CTs) are a leading source of outbreaks of Legionnaires’ disease (LD), a severe form of pneumonia caused by inhalation of aerosols containing Legionella bacteria.
LEGIONELLA - WHO ~ potentially hazardous environments, such as cooling towers, pools and spa baths. The document also identifies necessary measures to prevent, or adequately control, the risk of exposure to Legionella bacteria for each particular environment. Outbreaks of legionellosis generally cause
Eurosurveillance / Air-conditioner cooling towers as ~ Introduction Water supply and air-conditioner cooling towers (ACCT) are potential sources of Legionella pneumophila infection in people. During outbreaks, traditional typing methods cannot sufficiently segregate L. pneumophila strains to reliably trace back transmissions to these artificial water systems. Moreover, because multiple L. pneumophila strains may be present within these systems .

Welcome to CDC stacks ~ Cooling towers (CTs) are a leading source of outbreaks of Legionnaires' disease (LD), a severe form of pneumonia caused by inhalation of aerosols containing Legionella bacteria. Accordingly, proper maintenance of CTs is vital for the prevention of LD.
Legionnaires’ Disease Cases at a Large Community Hospital ~ 1. Introduction. One of the major causes of community-acquired pneumonia (CAP), Legionella bacteria are ubiquitous in nature, present in soil and water, and can thrive in man-made water systems, including domestic hot water tanks, decorative fountains, and HVAC (heating, ventilation, air conditioning) cooling towers. These bacteria get their name from a 1976 outbreak in a Philadelphia hotel .
Bacterial community dynamics and disinfection impact in ~ The microbiome characterization of a full-scale industrial cooling tower (2600 m 3 /h) - with residual chlorine between 0.35 and 0.41 mg-Cl 2 /L and concentration factor between 3.5 and 6.6 - and comparison of bacterial community structures between the water feeding the cooling tower and the cooling tower water led to the following conclusions:

What is Legionella Bacteria and Why is it Dangerous? ~ Standard 188 and the Cooling Tower Institute’s guideline “Legionellosis – Guideline: Best Practices for Control of Legionella” are currently the most widely cited works in the United States on the subject of preventing legionella in cooling towers. Portions of ASHRAE Standard 188 were even written into New York City’s cooling tower laws.

It provides guidance on assessment and management of risks associated with potentially hazardous environments, such as cooling towers, pools and spa baths. The document also identifies .
Comparison of Whole-Genome Sequences of Legionella ~ During the water crisis in Flint, Michigan, USA (2014–2015), 2 outbreaks of Legionnaires’ disease occurred in Genesee County, Michigan. We compared whole-genome sequences of 10 clinical Legionella pneumophila isolates submitted to a laboratory in Genesee County during the second outbreak with 103 water isolates collected the following year.
Frontiers / Development and Demonstration of Membrane to ~ The presence of pathogens in industrial cooling towers has been identified as one of the causes of legionellosis, but the tangible hazard has been unrecognized. The major function of a cooling tower in the industries is to transfer heat into the environment through evaporation which leads to an unusual increment in the conductivity of water.
