Paenibacillus Sepsis and Meningitis in a Premature Infant: A Case Report

Infections due to bacteria of the genus Paenibacillus are exceedingly rare and therefore predominately described on a case-by-case basis. Here, we present a case of a 25-day-old premature neonate who died from presumed Paenibacillus sepsis and meningitis. Most prior reported cases of Paenibacillus bacteremia were among patients who had prosthetic medical devices, were immunocompromised, or were injection drug users. However, to our knowledge, this is the first reported case of infant death from presumed Paenibacillus thiaminolyticus. This case suggests the potential for severe human infection by an environmental bacterium previously considered to be of little consequence.
