Streptococcus suis autolysin functions as a molecular bridge for epithelial adhesion via lipoteichoic acid interaction

Key Points

The study aims to uncover the role of autolysin Atl in promoting bacterial adhesion to epithelial cells.
Investigation of the interaction between autolysin Atl and epithelial cells in porcine and murine models.
Identification of key functional domains of Atl involved in adhesion mechanics.
Autolysin Atl significantly promotes Streptococcus suis adhesion to the upper respiratory tract epithelium.
Key functional domains of Atl were identified that enhance adhesion via interaction with lipoteichoic acid.

Abstract

) to both porcine and murine upper respiratory tract epithelium. This study reveals a novel function of the autolysin Atl in promoting SS2 adhesion to the upper respiratory tract epithelium, which elucidates the underlying molecular mechanism and identifies the key functional domains involved. These findings offer new insights into autolysin biology and provide a theoretical basis for developing anti-adhesion strategies against streptococcal infections in pigs.
