Effects and Diseases of the Bacterium Streptococcus Pyogenes The bacteria Streptococcus pyogenes has been infecting people for more than a century. Once a deadly bacterium, now only an antibiotic from curing the diseases it causes. Streptococcus pyogenes has been responsible for excruciating throat pains and even in some cases a horrendous rash included. This paper will talk about the history of this organism, how it acts as a pathogen, how people attract it, the symptoms that come with the disease, tests that can be implemented to identify if one has this bacteria, the treatments for the diseases, how people can prevent from getting the diseases, and what research is being conducted to cure the bacteria called Streptococcus pyogenes. The scientific name of this organism is called Streptococcus pyogenes. The common reference name for Streptococcus pyogenes is called Streptococcus. The names of the most common diseases caused by Streptococcus pyogenes are strep throat and scarlet fever. Scarlet fever is exactly the same disease as strep throat except for the addition of a skin rash. Streptococcus pyogenes was first documented in 1874 by Theodor Billroth while studying patients with wound infections. This disease was first discovered by Billroth however, it was not named until 1884 by Rosenbach (Khan, 2009). It was recorded that about 9,000-11,500 cases of invasive GAS disease occur each year in the United States, resulting in 1,000-1,800 deaths annually. STSS and necrotizing fasciitis each comprise an average of about 6%-7% of these invasive cases. In contrast, there are several million cases of strep throat and impetigo each year (Khan, 2009). Next will be about the structure of this bacterium and what enzymes or toxins it uses.

The structure of a Streptococcus Pyogenes cell has a capsule which is made of hyaluronic acid. The hyaluronic acid allows the bacterium to hide its own antigens and to unrecognized as antigenic by it host. Inside of the...
