Increased value of E-rosette test in aseptic meningitis after incubation with CSF

The influence of CSF on the active and total E-rosette test with peripheral blood (PB) lymphocytes of 12 children with aseptic meningitis (AM) was estimated. The control group included 10 children with convulsive fever. An increase in active and total T cells after incubation with CSF was observed in AM. This phenomenon might in part explain the higher proportion of T cells appearing in the CSF during aseptic meningitis. No changes were observed in the control group.
