Comparison of the cytolysin II genetic determinants of Actinobacillus pleuropneumoniae serotypes.

Cytolysins (Cly) I, II, and III are toxins secreted by Actinobacillus pleuropneumoniae. These toxins are thought to play an important role in the pathogenesis of porcine pleuropneumonia. ClyI and ClyII are RTX toxins and in general these toxins are encoded by operons consisting of four genes, C, A, B, and D. Our group recently cloned the C and A genes of… CONTINUE READING
