Necropsobacter rosorum (N. rosorum) is a gram-negative organism previously classified under the family Pasteurellaceae. It has been isolated from the gastrointestinal and respiratory tracts of mammals. On the other hand, there is very little information available about how N. rosorum infects human. Due to a paucity of information in the database, commercial identification methods such as VITEK identification system or Analytical Profile Index (API) frequently misidentify this organism. Thus, it is a challenge for laboratories to accurately identify N. rosorum. By using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF), we were able to identify N. rosorum in a patient with sepsis secondary to wet gangrene of the left big toe. This case report aims to shed light on the application of advance diagnostic tests for the early detection of human pathogens.
