Liver Abscess1
Pyogenic liver abscess is associated with S. anginosus and in studies in the 1970s was reported to be the most common cause of hepatic abscess. (wikipedia.org)
In contrast to the pyogenic group streptococci, our knowledge of the virulence factors of the anginosus group streptococci, including S. anginosus, is not sufficient to allow a clear understanding of the basis of their pathogenicity. (tokushima-u.ac.jp)
Interestingly, contrary to pyogenic group streptococci, beta-hemolytic S. anginosus was shown to have two tandem sagA homologues, encoding streptolysin S (SLS)-like peptides, in the sag operon homologue. (tokushima-u.ac.jp)
These data suggest that SLS-like peptides encoded by two sagA homologues in beta-hemolytic S. anginosus may be potential virulence factors with a different structure essential for hemolytic activity and/or the maturation process compared to the typical SLS present in pyogenic group streptococci.

It was noted that the duration of symptoms is longer with liver abscesses associated with S. anginosus than with other microorganisms. (wikipedia.org)
Beta-hemolysis2
In the present study, a sag operon homologue was shown to be responsible for beta-hemolysis in S. anginosus strains by random gene knockout. (tokushima-u.ac.jp)
Gene deletion and complementation experiments revealed that both genes were functional, and these SLS-like peptides were essential for beta-hemolysis in beta-hemolytic S. anginosus. (tokushima-u.ac.jp)
