Pneumocystis jirovecii has gained attention during the last decade in the context of the AIDS epidemic and the increasing use of cytotoxic and immunosuppressive therapies. This article summarizes current knowledge on biology, pathophysiology, epidemiology, diagnosis, prevention, and treatment of pulmonary P jirovecii infection, with a particular focus on the evolving pathophysiology and epidemiology. Pneumocystis pneumonia still remains a severe opportunistic infection, associated with a high mortality rate.

ReviewSwine Influenza (H1N1) pneumonia: clinical considerations.
Influenza is a viral zoonosis of birds and mammals that has probably existed since antiquity. Attack rates of influenza are relatively high but mortality is relatively low. ⋯ Influenza has the potential for rapid spread and may involve large populations. This article examines the swine influenza (H1N1) strain of recent origin, and compares the microbiology, epidemiology, clinical presentation, differential, clinical, and laboratory diagnosis, therapy, complications, and prognosis with previous recorded outbreaks of avian and human seasonal influenza pneumonias.

Francisella tularensis is a zoonotic infection that can be acquired in multiple ways, including a bite from an arthropod, the handling of animal carcasses, consumption of contaminated food and water, or inhalation of infected particles. The most virulent subspecies of F tularensis is type A, which is almost exclusively seen in North America. Pneumonia can occur in tularemia, as either a primary process from direct inhalation, or as a secondary manifestation of ulceroglandular or typhoidal disease. This article describes the history of this infection, epidemiology, methods of diagnosis and treatment, and its potential as a bioterrorism weapon.
