NEONATAL MENINGITIS due to bacteria of the genus Proteus is extremely rare.1 At the present time, only 17 proven cases have been reported in the literature,1 and of these, six have been caused by Proteus mirabilis.2-6 Paralleling the experience with neonatal meningitis in general, almost all of these cases either ended in death or developed severe neurological sequelae. It is the purpose of this paper to report two additional cases of P mirabilis meningitis in the neonatal period and to review the special features of, and the literature in, this disease.
