Enterobacter agglomerans, an uncommon cause of community-acquired bacterial infection in neonates

Enterobacter agglomerans formerly termed Erwina herbicola but now called Pantonea agglomerans is a ubiquitous gram-negative bacterium that rarely causes mild and opportunistic infection in humans. Sources of infection are myriad causing both local and systemic disease across all systems of the body. Infection is often fulminant and fatal in neonates. We aim to report another facet of the infection as seen in our centre. Of the 248 neonates recruited into the study, 94 had bacteria isolated from their blood, eight (8.5%) of whom had E. agglomerans sepsis. Infection was acquired from the community though its source could not be determined. The clinical features were non-specific running a mild course. Toxic granulation, elevated immature polymorph count and procalcitonin level was found in 50% and 75% of the neonates. Isolate was sensitive to most tested antibiotics, showing 100% sensitivity to gentamicin and ciprofloxacin and the survival rate was excellent (87.5%).
