LANSING, Mich. (WZZM) -- Testing by the Ingham County Health Department has found the bacterial infection that killed a Wyoming teenager and Michigan State University student was likely not meningitis.

A health department spokesman says tests so far on the bacteria that killed Carly Glynn have been negative for meningitis. Marcus Cheatham says while meningitis is still possible, the negative tests make it much less likely.

Glynn, 19, died Thursday night at Sparrow Hospital in Lansing, hours after falling ill in her dorm at Michigan State.

Cheatham says none on the 34 people who could have been exposed to the bacteria that causes meningitis has become sick.

The spokesman says further testing is underway, and the cause of Glynn's death is still under investigation.
