and Legionnaires' disease: Time to explore in India.

Legionella pneumophila was first recognised as a fatal cause of pneumonia more than four decades ago, during the 1976-American Legion convention in Philadelphia, USA. Legionella spp. continue to cause disease outbreaks of public health significance, and at present, Legionnaires' disease (LD) has emerged as an important cause of community and hospital-acquired pneumonia.

Multiplex polymerase chain reaction of genetic markers for detection of potentially pathogenic environmental isolates.

Background & Objectives: Genomic constitution of the bacterium Legionella pneumophila plays an important role in providing them a pathogenic potential. Here, we report the standardization and application of multiplex polymerase chain reaction (PCR) for the detection of molecular markers of pathogenic potential in L. pneumophila in hospital environment.

Legionella pneumophila Serogroup 1 in the Water Facilities of a Tertiary Healthcare Center, India.

Proactive environmental surveillance for Legionella pneumophila in hospitals that treat immunocompromised patients is a useful strategy for preventing nosocomial Legionnaires' disease. We report the presence of L. pneumophila serogroup 1 in 15.

Detection of and in Patients Having Community-Acquired Pneumonia: A Multicentric Study from New Delhi, India.

Atypical pathogens including and are increasingly recognized as important causes of community-acquired pneumonia (CAP). accounts for 20-40% of all CAP and is responsible for 3-15% of cases. The paucity of data from India in this regard prompted us to conduct this prospective multicentric analysis to detect the prevalence of and in our geographical region.
