Abstract

Abstract: Eggerthia catenaformis is a Gram-positive bacilli and an anaerobic and non-spore-forming bacterium, which rarely causes infections in humans. We present a case of peritonitis caused by E. catenaformis in a peritoneal dialysis patient. The isolate was identified as E. catenaformis with the MALDI-TOF MS method as in other cases in the literature. To the best of our knowledge, this is the first case of peritonitis caused by E. catenaformis in a human host. Highlights: Eggerthia catenaformis ( E. catenaformis ) is a Gram-positive bacilli, which was named as Lactobacillus catenaformis before 2011. It is an anerobic, non-spore-forming bacterium belonging to the Erysipelotrichaceae family. It was first detected in human feces in 1935. To date, only six cases of infection caused by E. catenaformis have been reported. MALDI-TOF MS plays an important role in a convenient identification of anaerobic bacteria such as E. catenaformis. Microbiologist and clinicians should be aware of the possibility that the pathogen may cause a severe infection rather than being a mere contaminant.
