Bioterrorism: A laboratory who does it?

In October 2001, the first disseminated biological warfare attack was perpetrated on American soil. Initially, a few clinical microbiology laboratories were testing specimens from acutely ill patients and also being asked to test nasal swabs from the potentially exposed. Soon after, a significant number of clinical microbiology and public health laboratories received similar requests to test the worried well or evaluate potentially contaminated mail or environmental materials, sometimes from their own break rooms. The role of the clinical and public health microbiology laboratory in response to a select agent event or act of bioterrorism is reviewed.
