  • Scarlet Fever.
  • Impetigo.
  • Type II Necrotizing Fasciitis.
  • Cellulitis.
  • Streptococcal Toxic Shock Syndrome.
  • Acute Rheumatic Fever.
  • Post-Streptococcal Glomerulonephritis.
  • Where does Group A Streptococcus bacteria come from?

    Group A strep bacteria are spread by direct contact with body fluids, such as secretions from the nose and throat or wound drainage from an infected person. Casual contact (as in work and school) and household items (like toys) rarely play any role in spreading the bacteria.

    How do you get streptococcus bacteria?

    These bacteria are spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin. The risk of spreading the infection is highest when a person is ill, such as when people have “strep throat” or an infected wound.

    What is Group C streptococcus?

    Group C streptococci (GCS) are livestock pathogens and they often cause zoonotic diseases in humans. They are Gram-positive, in mostly β-hemolytic and facultative anaerobes.

    How did I get strep?

    Strep throat is caused by infection with a bacterium known as Streptococcus pyogenes, also called group A streptococcus. Streptococcal bacteria are contagious. They can spread through droplets when someone with the infection coughs or sneezes, or through shared food or drinks.

    What are the different groups of Streptococcus?

    Most strep infections can be treated with antibiotics. Streptococci infections are divided into several groups: Group A streptococcus, Group B streptococcus, Group C streptococcus, and Group G streptococcus. Group A strep , sometimes called GAS, tends to affect the throat and the skin.

    How does Streptococcus Group an affect the body system?

    Once the streptococcus bacteria group A enters your nose or mouth, the germs will attack the tissues of your throat.

As the bacteria grow, the pain in your throat will develop and you may have a fever that signals your body is still fighting.

    What is a group B streptococcus carrier?

    Group B Streptococcus (GBS) is a type of bacterial infection that naturally lives in the intestines and migrates down to the urinary tract, vagina and/or rectum. (Group B strep is not a sexually transmitted disease.) Both men and women can be “carriers” or are “colonized” with GBS.

    How did I get Group B Strep?

    Group B strep infections are caused by bacteria from the species and genus Streptococcus agalactiae. Streptococci were divided into groups in 1933 by mixing the strains with antibodies that were produced in rabbits.
