The university said Saturday that its researcher studied the genetics of harmful bacteria including Yersinia pestis, which causes the illness. He died September 13. His name and age haven't been released.

The medical center says the bacteria he worked with was 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 are planned. No other illnesses have been reported.
