Brucellosis is characterized by fever, night sweats, and arthralgias, but pneumonia is rare. Anthrax and plague can cause severe pneumonia. [2]
C. burnetti, the causative agent of Q fever, causes pneumonia, fevers, night sweats, myalgias, and hepatitis. [2]

Toxoplasma gondii, an intracellular protozoan, is estimated to have infected one third of the world’s population. In immunocompetent hosts, the infection is typically either asymptomatic or a self-limited mononucleosis-like illness. The parasite is commonly acquired by ingesting viable organisms in food, water, or soil. Disseminated toxoplasmosis is rare as a cause of pneumonia in immunocompetent persons. Symptomatic T. gondii infections in immunocompetent patients may be associated with lymphadenopathy, myalgias, and rash. [2]
