Searching Simkania negevensis in environmental waters.

Simkania negevensis is an obligate intracellular bacterium grouped into the order Chlamydiales. This new amoeba-resistant bacterium represents a novel aetiologic agent of bronchiolitis and community-acquired pneumonia in both adults and children. It has been suggested that Simkania could be an ubiquitous microorganism presented in water environments.

Prevalence study of Simkania negevensis in cooling towers in Spain.

Simkania negevensis is an obligate intracellular bacterium grouped into the order Chlamydiales. This new amoeba-resistant intracellular bacterium might represent a novel etiologic agent of bronchiolitis and community-acquired pneumonia and occurs in aquatic habitats such as drinking water and reclaimed wastewater. Another amoeba-related bacterium, Legionella pneumophila, is an etiologic agent of pneumonia transmitted by environmental aerosols or contaminated water/air cooling systems.
