Abstract

Roseomonas aerofrigidensis is a gram-negative, strictly aerobic, non-motile bacterium, which was first isolated in 2017 in South Korea. We present the first report of the isolation of R.aerofrigidensis from the peritoneal fluid of a 38-year-old woman with a history of metastatic gastric cancer with peritoneal carcinomatosis. The isolate was resistant to cotrimoxazole. Further research on clinical and microbiological responses to several antibiotics are warranted.
