Contraction and Spread of Streptococcus pyogenes
Abstract:
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. It is also possible to be infected through abrasions of the skin, which can result in cellulitis, impetigo, or even necrotizing fasciitis. Aside from human to human contact, these bacteria can also be found in unpasteurized milk. There is no vaccine for Streptococcal infections, though antibiotics such as penicillin still work very well against them.

It is also very transmissible through shaking hands, and handling something that a person with infected with pyogenes has touched. These are the most common ways to contract Strep. throat. (2,3)
Also, contraction is very possible through the skin via abrasions both small and large. This type of infection would be contracted from exposure to other people harboring the bacteria, bacteria in the air, or bacteria on the injured person. Being infected this way can rarely result in necrotizing fasciitis. It is also very possible, albeit very rare, that Streptococcus pyogenes can be transmitted through food, most notably milk and its products. This form of infection is usually caused by improper or lack of pasteurization of the milk. The bacteria that are responsible hardly ever come from an outside source, and are usually present within the cow when infected milk is produced. However, these two other methods of transmission are far less likely than the usual human-to-human respiratory infections. (6,2,1)
After the bacteria are first taken into the body, there is an incubation period of between one and five days. During incubation the bacteria are very capable of infected others without the host having any knowledge of an infection. This is important in the spread of Strep. infections, which will often occur through contact between children while at school. It is no mistake that the
