Y1 - 2015 N1 - T2 - Fishman's Pulmonary Diseases and Disorders, 5e AB - Many different microorganisms can infect the lung parenchyma; this chapter focuses on zoonoses, human commensals, and other unusual bacterial pathogens. Routes of spread to the lungs are few, clinical presentations overlap, radiologic appearance often is nonspecific, and pathophysiologic mechanisms are limited. Making a clinical diagnosis of pneumonia is relatively easy; defining the causative agent can be difficult. The search for the specific etiologic agent is driven by the desire to administer a specific antimicrobial drug as soon as possible hopefully to avoid progressive functional impairment and to contain spread to other individuals or to a community. Identifying a pathogen may, in turn, expand epidemiologic considerations and public health awareness.
