Summary Introduction
Introduction:
Group A Streptococcus is the cause of scarlet fever, rheumatic fever, and bacterial pharyngitis. This survives in the body using several factors, including M protein, pyrogenic toxins, a hyaluronic acid, streptolysin, and enzymes. These allow the pathogen to spread in many different ways in the human body.
