How do you treat Streptococcus pyogenes?
The drug of choice for treatment of bacterial pharyngitis is oral penicillin for 10 days or IM benzathine penicillin. This treatment is cost-effective and has a narrow spectrum of activity. Severe invasive S. pyogenes infections can be treated with vancomycin or clindamycin.
What is the role of Streptococcus?
Streptococcus pyogenes (Group A Streptococcus; GAS) is a human pathogen responsible for a wide variety of human diseases (Walker et al., 2014). The major manifestations of GAS infections are local suppurative inflammation in the upper respiratory tract and skin, i.e., pharyngitis and impetigo.
What does Streptococcus pyogenes cause?
Life-threatening infections caused by Streptococcus pyogenes (group A streptococcus) include scarlet fever, bacteremia, pneumonia, necrotizing fasciitis, myonecrosis and Streptococcal Toxic Shock Syndrome (StrepTSS).
What does Streptococcus pyogenes need to survive?
Researchers have discovered that Streptococcus pyogenes, a species of bacteria that can cause severe illness if it invades the human body, can survive on the skin using arginine as a source of nutrition. Breakdown of a skin protein called filaggrin is a likely source of arginine.
What antibiotic treats Streptococcus?
Doctors most often prescribe penicillin or amoxicillin (Amoxil) to treat strep throat. They are the top choices because they’re safer, inexpensive, and they work well on strep bacteria.
Which antibiotic is more effective against Streptococcus pyogenes?
To date, S pyogenes has remained universally susceptible to penicillin. Therefore, penicillin remains the first-line drug of choice for pharyngeal infections, as well as for complicated or invasive infections.
How do you get Streptococcus?
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 causes Streptococcus?

Inflammation of the kidney (poststreptococcal glomerulonephritis) Rheumatic fever, a serious inflammatory condition that can affect the heart, joints, nervous system and skin.
Is Streptococcus pyogenes harmful or helpful to humans?
Streptococcus pyogenes is an important global human pathogen that causes a wide variety of acute infections, such as soft tissue infections and pharyngitis; severe life-threatening infections, such as streptococcal toxic shock syndrome; and devastating postinfectious sequelae, such as rheumatic fever and …
