Answer

A history of various exposures, such as travel, animal, occupational, and environmental exposures, can be helpful in determining possible etiologies and the likelihood of bacterial pneumonia, as follows:

  • Exposure to contaminated air-conditioning or water systems – Legionella species

  • Exposure to overcrowded institutions (eg, jails, homeless shelters) -S pneumoniae, Mycobacteria, Mycoplasma, Chlamydophila

  • Exposure to various types of animals - Cats, cattle, sheep, goats (C burnetii, B anthracis [cattle hide]; turkeys, chickens, ducks, or other birds (C psittaci); rabbits, rodents (F tularensis, Y pestis)
