Laribacter hongkongensis is a potential emerging pathogen associated with community-acquired gastroenteritis and traveler's diarrhea. We report the isolation of L. hongkongensis from the stool of a patient who had no history of travel outside the United States. The organism was identified by phenotypic tests, mass spectrometry, and gene sequencing.
