PY - 2023 T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - Many different microorganisms can infect the lung parenchyma; the focus in this chapter is pneumonias caused by zoonoses, environmental pathogens, and other unusual bacterial pathogens. Making a clinical diagnosis of pneumonia is relatively easy; defining the causative agent can be difficult. Routes of spread to the lungs are few, clinical presentations overlap, radiologic appearance often is nonspecific, and pathophysiologic mechanisms are limited. The search for the specific etiologic agent is driven by the desire to administer a specific antimicrobial drug as soon as possible, hopefully avoiding progressive functional impairment and containing spread to other individuals or to a community. Identifying a pathogen may, in turn, expand epidemiologic considerations and public health awareness.
