Unusual Multiple Brain Abscesses Caused by Aeromonas hydrophila in a Preterm Neonate: Case Report

Abstract

AbstractNeonatal brain abscess is rare. The most common etiologic microorganisms that are responsible for this condition are Citrobacter diversus, Proteus mirabilis, Pseudomonas aeruginosa, Serratia marcescens, and other Enterobacteriaceae. Aeromonas hydrophila is a halophilic, gram-negative, facultative anaerobic bacillus.It has been reported to cause intestinal and extraintestinal infections and has rarely been reported to cause meningitis at neonatal age. A. hydrophila has not been reported previously to cause brain abscess in neonates. In this report, we describe a case of severe multiple brain abscesses and ventriculitis as complications in meningitis caused by A. hydrophila in a preterm newborn.
