Man's death may be linked to bacteria

2:00 a.m. September 20, 2009

CHICAGO — The University of Chicago Medical Center reported yesterday that the infection that killed a scientist Sept. 13 may be connected to bacteria he researched that cause the plague.

The university said its researcher studied the genetics of harmful bacteria including Yersinia pestis, which causes the illness. His name and age haven't been released. The medical center said the bacteria he worked with were from a weakened strain that isn't known to cause illness in healthy adults. The strain was approved by the Centers for Disease Control and Prevention for laboratory studies.

An autopsy found no obvious cause of death but did find the presence of the bacteria. More tests were planned. No other illnesses have been reported.
