Bacterial adherence and upper respiratory tract disease: a correlation between S. pyogenes attachment and recurrent throat infections.

The attachment of bacteria to mucosal surfaces is the initial event in the pathogenesis of infectious diseases. The authors present a study about the adherence of strain of S. pyogenes isolated in subjects with recurrent tonsillitis. A correlation was found between the adherence ability of the bacterium and the number of episodes per year. The study about the SIgA, the infection development and the bacterium adherence showed a direct correlation between SIgA levels and the number of phlogistic episodes. The importance of the role assumed by bacterial adherence in the genesis of the phlogistic process is to be emphasized yet again.
