Legionella Test

Description

Infection caused by waterborne organisms from contaminated water sources and the subsequent burden of disease is not merely a problem for developing countries; it also poses a significant threat in countries with established water treatment procedures and infrastructures, especially for healthcare facilities treating immunocompromised or critically ill patients. Recent investigations revealed cases of L. pneumophila and M. abscessus infections that were transmitted via dental unit water systems such as contaminated high-speed handpiece lines.

A better understanding of the potential for microbial contamination in healthcare equipment waterlines has spurred the development of multiple infection prevention strategies to prevent water contamination. Appropriate implementation of these procedures and treatments is especially important as the number of immunocompromised patientsreceiving dental and medical care steadily increases.

It should be emphasized that tap water is considered to be a major reservoir for M. abscessus and other NTM, and that this vehicle has been traced as a source for patient exposure and resultant clinical infection. This fact is especially pertinent when considering the recent outbreaks involving this organism in pediatric dentistry offices. Evidence suggests that a number of patients were infected from treatment water used during pulpotomy procedures.
