A case of human diarrhea caused by Gallibacterium anatis: a case report.

Gallibacterium anatis (G. anatis) is an opportunistic pathogen previously associated with deaths in poultry and is also a pathogen that rarely causes human diseases. G. anatis has only been reported twice as the causative agent of a human disease (both in France). Here, we report a 62-year-old male patient with hypertension and type 2 diabetes who suffered from acute watery diarrhea caused by this bacterium which was identified by MALDI-TOF MS and 16 S rRNA sequencing. Despite human diarrhea caused by G.anatis is rare, with the continuous emergence of multidrug-resistant isolates of G. anatis in recent years, this case report will inform clinicians that G. anatis especially drug-resistant G. anatis may be a possible infectious source of human diarrhea in immune-suppressed populations.
