Contraction and Spread of Streptococcus pyogenes. Streptococcus pyogenes is a very common bacteria found in humans. It is very transmissible and can be caught through the air via coughing or sneezing. This form of Strep. illness is referred to as Streptococcal pharyngitis, also known as Strep. throat, which can complicate into Scarlet Fever.
Streptococcus pyogenes is a species of bacteria. Like most other streptococci, it is clinically important in human illness.It is an infrequent, but usually pathogenic, part of the skin flora. It is the sole species of Lancefield group A and is often called group A streptococcus (GAS), because it displays streptococcal group A antigen on its cell wall.Group A streptococcal infection can cause illness, which typically produces small zones of beta-hemolysis, a complete destruction of red blood cells.(A zone size of 2-3 mm is typical). It is thus also called group A (beta-hemolytic) streptococcus (GABHS). Like other cocci, streptococci are round bacteria.roup A streptococcal infection can cause illness, which typically produces small zones of beta-hemolysis, a complete destruction of red blood cells.
