All of the following organisms are known to survive intracellularly, EXCEPT:
Streptococcus pyogenes is a gram-positive cocci in chains. It is beta hemolytic, catalase-negative and bacitracin sensitive. It does not survive intracellularly. It is subdivided into groups based on the differences in the antigenicity of their cell wall carbohydrate. It is transmitted respiratory droplets. It can result in suppurative diseases such as pharyngitis and cellulitis, nonsuppurative diseases such as rheumatic fever and acute glomerulonephritis.
