Intrinsically Resistant Bacteria as Looming Disaster: A Rare Case Report of Elizabethkingia meningoseptica Meningitis in a Neonate

Abstract

Elizabethkingia meningoseptica is a recognized cause of neonatal meningitis with high mortality rate of approximately 57%, but clinical data detailing these infections remain limited from India. Though this bacteria has a Gram-negative character, it is usually multidrug resistant to antibiotics usually prescribed for Gram-negative bacterial infections and susceptible to antibiotics for Gram-positive bacteria, thus poses a serious challenge to the treating clinicians. Such cases of neonatal meningitis is most commonly associated with prematurity with birth weight < 2,500 g, but here we report an uncommon case of neonatal meningitis due to this rare pathogen in a full-term neonate with weight as per gestational age. The isolate was multidrug resistant and discrepancy was seen between disc diffusion and automated antibiotic susceptibility testing for few antibiotics. The case was successfully managed by treatment with combination of piperacillin-tazobactam, vancomycin, chloramphenicol, and rifampicin for a total duration of 28 days, due to prompt identification of the causative organism and initiation of appropriate antimicrobial therapy early. E. meningoseptica can cause severe infection, with risk of high mortality and neurological sequelae in neonates. Intensive care and multidisciplinary interventions are crucial for case management.
