Detection of L. pneumophila non-serogroup 1 in hospital-acquired pneumonia: A cross-sectional study from Eastern India

This study highlights the significant role of Lp non serogroup 1 as a pathogen in 12.5% of microbiologically confirmed HAP cases, using PCR, which were negative by culture and commercially available urinary antigen testing targeting Lp serogroup 1. The findings emphasize incorporating Lp molecular tests along with Ag testing in the diagnostic algorithm of HAP cases.
