[The composition of the cerebrospinal fluid in children with tuberculous meningitis with different patterns of the mycobacterial population].

Composition of the liquor with regard of mycobacterial population was investigated in 113 children with tuberculosis meningitis. The changes in the liquor were most pronounced in bacterial variant of the causative agent and were minimal in the absence of both bacterial and L-forms of M. tuberculosis. This, however, does not mean that tuberculosis etiology of meningitis is ruled out.
