Hundreds of Michigan State University students lined up today for vaccines against bacterial meningitis, and a student remained in the hospital battling the infection.

Adam Busuttil was in critical condition Sunday, his doctor said, and the university said his condition was unchanged this morning. Officials declined to update his condition this afternoon, at his family's request.

Busuttil became ill Friday and passed out Saturday night from the bacterial infection, meningococcal meningitis. The sophomore is studying instrumental music education and plays the cymbals in the Michigan State marching band.

The university is offering antibiotics to anyone who may have come into close contact with Busuttil, including the 950 people who live in his dorm and the 300 members of the band. It also is offering the university community a vaccine and is picking up the $50-per-person cost until Nov. 1.

The antibiotics treat the infection and the vaccine is a preventive measure, but is ineffective against one of the five forms of meningococcal meningitis, officials said. They will not know which strain Busuttil has until later this week.

Meningitis is a swelling of the lining surrounding the brain and spinal cord and comes in two forms--the common, less serious viral meningitis, and the rare bacterial meningitis, which can be fatal. Busuttil has the bacterial type.

Several hundreds of students lined up for the vaccines today.
