Streptococcus pyogens

[amoeboidmovement]

Is Streptococcus pyogenes normal microbiota? If it is, where? Upper respiratory, nasal?

[MrMistery]

i think it's just parasitic.

Basically, S. pyogenes is an important human pathogen that should be treated if detected. Typically it can be isolated from throat swabs or from abscesses it makes. Now and then it can cause severe infections such as necrotizing fascitis, and secondary reactions after the primary infection can be difficult as well (for example rheumatic artritis, which is an autoimmune reaction after the initial infection, such as tonsillitis).

That being said, sometimes S. pyogenes can be found from healthy individuals who have become colonized by the microbe, but do not develop a disease. These people may spread the bacteria to their environment.
