Chemotaxis of Pathogenic <i>Vibrio</i> Strains towards Mucus Surfaces of Gilt-Head Sea Bream ( <i>Sparus aurata</i> L.)

Abstract

Vibrio anguillarum and Vibrio alginolyticus exhibited significant adhesion to and chemotactic abilities towards mucus collected from the skin, gills, and intestine of gilt-head sea bream. Quadratic polynomial models for chemotaxis designed to estimate the influence of temperature demonstrated a differential bacterial chemotaxis depending of the source of the mucus, with the chemotaxis towards intestinal mucus being the least influenced.
