Group A streptococci (GAS) can cause various diseases, including strep throat, skin and soft-tissue infections (eg, pyoderma, erysipelas, cellulitis, necrotizing fasciitis, myositis, osteomyelitis, pneumonia, abscess), severe systemic disease, and long-term nonsuppurative complications (eg, rheumatic fever, acute glomerulonephritis).
What is possible origin of Streptococcus?
The term was coined in 1877 by Viennese surgeon Albert Theodor Billroth (1829-1894), by combining the prefix “strepto-” (from Ancient Greek: στρεπτός, romanized : streptós, lit. ‘easily twisted, pliant’ ), together with the suffix “-coccus” (from Modern Latin: coccus, from Ancient Greek: κόκκος, romanized: kókkos, lit. ‘grain, seed, berry’.)
How dangerous is Streptococcus pneumoniae?
S. pneumoniae is alpha-hemolytic, meaning that it can break down red blood cells through the production of hydrogen peroxide (H2O2). The production of H2O2 by the bacterial infection can also cause damage to DNA, and kill cells within the lungs.
