Simkania negevensis, a Chlamydiae (PubMed).
Grows in amoebae (and macrophages) and is found in water, including tap water and spas.
Community-acquired pneumonia but rare (<2%) and bronchiolitis. Perhaps more of a kids pathogen. Diagnose with PCR or serology but not available where I work.
Tetracyclines and macrolides? Sulfa and quinolone resistant.
