A bizarre series of events in a college microbiology lab class left 33 people—including students, professors, and lab workers—believing they were exposed to a deadly germ. Of those, 32 began taking an antibiotic regimen as a precaution to prevent a life-threatening infection. Two also underwent lumbar punctures—aka spinal taps—after developing mild symptoms.
But none of them had actually been exposed to a dangerous pathogen, a fortunate twist in the strange incident, which otherwise stands to be a cautionary tale for the ages. The incident was published in a recent issue of Morbidity and Mortality Weekly Report.
It began with a simple laboratory exercise. The microbiology lab students were supposed to be given mystery bacteria by their instructors and then identify the microbe based on a series of biochemical tests and morphological characterization.
