Rapid and definitive diagnosis of infectious diseases using peripheral blood smears.
A timely diagnosis is essential in the management of septicemia and septic shock.  Three patients are described, all of whom presented with fever and one of whom was hypotensive at the time of admission. In each patient, rapid diagnosis of the cause of fever was possible because microorganisms were identified on a peripheral blood smear obtained at the time of admission.  This identification permitted prompt initiation of appropriate antimicrobial therapy.  In addition, a literature review of use of peripheral blood smears in the diagnosis of bacterial, fungal, and parasitic infections is provided.
