CMV induced meningitis in the immunosuppressed

[J.S.Kloover]

I'm a second year student in Medicine, facing the following problem:

When immunosuppressed laboratory rats are intrathecally infected, they 
develop a meningitis, instead of a encephalitis, according to our 
experimental setting. There is literature available about HCMV induced 
encephalitis, but little is published about HCMV induced meningitis.
Any kind of information on this subject is welcome !!
