Effects on the motility of commensal bacteria by Scy-hepc. a, Transmission electron microscope showing the morphological observation of V. harveyi and b, B. thuringiensis isolated from the fish gut in this study. c, morphological changes of bacterial cells in the presence of Scy-hepc as observed by scanning electron microscopy. d, mucin induced swift surface motility across diverse bacterial species. V. harveyi and B. thuringiensis were grown under surfing conditions (0.3% agar in the presence of 0.4% mucin) in 2216E and BHI with different treatment groups (n = 5, *P < 0.05, **P < 0.01). Experiments replicated at least twice
