Description:Under a magnification of 500X, this Brown and Brenn-stained photomicrograph of a lung section specimen, revealed the presence an intra-alveolar exudate containing macrophages, and polymorphonuclear (PMN) leukocytes in a case of Legionellosis, due to the bacterium, Legionella pneumophila.
Legionnaires' disease, (LD), is the more severe form of legionellosis, and is characterized by pneumonia, commencing 2-10 days after exposure. Pontiac fever is an acute-onset, flu-like, non-pneumonic illness, occurring within a few hours to two days of exposure.
