Abstract

Legionnaires' disease is a severe form of lung infection caused by bacteria belonging to the genus . The disease severity depends on both host immunity and virulence. The objective of this study was to describe the pathological spectrum of acute pneumonia caused by a virulent clinical isolate of serogroup 1, sequence type 62. In A/JOlaHsd mice, we compared two infectious doses, namely, 10 and 10 CFU, and their impact on the mouse status, bacterial clearance, lung pathology, and blood count parameters was studied. Acute pneumonia resembling Legionnaires' disease has been described in detail.
