Autoaggregation in Streptococcus intermedius is driven by the Pel polysaccharide

D. Raju, S. A. Turner, K. Castro, G. B. Whitfield, D. LaMarche, S. Mahajan, R. Pfoh, F. Le Mauff, M. Joe, S. Sarkar, T. L. Lowary, D. C. Sheppard, D. J. Wozniak, M. G. Surette, P. L. Howell

This study identifies the Pel polysaccharide as a driver of autoaggregation in S. intermedius, linking it to biofilm formation and increased pathogenicity.
