Streptococcus pyogenes Streptococcus py·og·e·nes (pī-ŏj'ə-nēz)
A bacterium that causes the formation of pus or of fatal septicemias.
Cultivations from the liver gave a pure growth of what appeared to be a typical (non-capsulated) streptococcus pyogenes longus.
streptococcus pyogenes is found in spreading suppurations and in very acute abscesses.
Like septicæmia, this condition is due to pyogenic bacteria, the streptococcus pyogenes being the commonest organism found.
This may be a wound or a purulent blister, and the streptococcus pyogenes is the organism most frequently present.
