Matrix-assisted laser desorption ionisation-time of flight mass spectrometry for rapid identification of Laribacter hongkongensis.

Laribacter hongkongensis is a Gram-negative, facultative anaerobic, motile, S-shaped, urease-positive bacillus associated with invasive infections in liver cirrhosis patients and community-acquired gastroenteritis. Most cases of L hongkongensis infections occur in eastern countries. Information is lacking on the usefulness of matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) for the identification of bacteria important in eastern countries.
