Health officials have allowed San Francisco State University to reopen a classroom where a test tube broke, spilling a culture of the bacterium that causes bubonic plague. Inspectors determined that the school used proper measures to eliminate any public health threat, said Paul Barnes, a spokesman for the Department of Public Health in San Francisco. A biology lecturer had dropped a test tube as she and a student were clearing a room after a microbiology class. The lecturer flooded the area with disinfectant and cleaned it with Clorox, then the room was closed.
