Mice Infected With Bubonic Plague Missing

Three mice infected with the bacteria responsible for bubonic plague apparently disappeared from a laboratory about two weeks ago, and authorities launched a search though health experts said there was scant public risk.

The mice were unaccounted-for at the Public Health Research Institute, which is on the campus of the University of Medicine and Dentistry of New Jersey and conducts bioterrorism research for the federal government.

Federal official said the mice may never be accounted for. Among other things, the rodents may have been stolen, eaten by other lab animals or just misplaced in a paperwork error.

If the mice got outside the lab, they would have already died from the disease, state Health Commissioner Fred Jacobs said.
