Susceptibility patterns of clinical and fish isolates of Laribacter hongkongensis: comparison of the Etest, disc diffusion and broth microdilution methods.

Objectives: To determine the antibiotic susceptibility patterns of 60 strains of Laribacter hongkongensis isolated from humans and fish to eight antibiotics and compare the results obtained from broth microdilution, Etest and disc diffusion susceptibility testing.

Patients And Methods: The susceptibilities of 60 isolates of L. hongkongensis from humans with gastroenteritis and fish to eight antibiotics were tested by three methods [broth microdilution (reference method), Etest and disc diffusion] and their results were compared.

Isolation of Laribacter hongkongensis, a novel bacterium associated with gastroenteritis, from Chinese tiger frog.

Laribacter hongkongensis is a recently discovered novel bacterium associated with community-acquired gastroenteritis. Although the bacterium has been isolated from freshwater fish and natural freshwater environments, it is not known if other freshwater animals could also be a source of L. hongkongensis.
