Chemotactic activity of cerebrospinal fluid in pyogenic meningitis.

Cerebrospinal fluid from patients with pyogenic meningitis was found to be chemotactic for polymorphonuclear neutrophil leucocytes. No significant difference was found between the mean chemotactic activity of cerebrospinal fluid obtained from patients with pneumococcal meningitis or meningococcal meningitis. The chemotactic factor present in cerebrospinal fluid is probably a low molecular weight protein, perhaps a complement component. [ABSTRACT FROM PUBLISHER]
