title: Isolation of Corynebacterium aquaticum from spinal fluid of an infant with meningitis.
abstract: A 4-week-old female was hospitalized because of vomiting, irritability, and nuchal rigidity. A spinal fluid culture yielded Corynebacterium aquaticum. The diagnosis of C. aquaticum meningitis in this infant was supported by the following cerebrospinal fluid findings: Gram stain, elevated protein, hypoglycorrhachia, positive C-reactive protein, and polymorphonuclear leukocytosis. Antigen studies for common bacterial causes of meningitis were negative. C. aquaticum is a rare cause of human disease and may be initially confused with Listeria monocytogenes, which is a more common gram-positive, motile rod associated with meningitis in infants.
