Acute rheumatic fever can follow pharyngitis caused by specific rheumatogenic strains of *S. pyogenes* (strains 1, 3, 5, 6, and 18). Although the exact mechanism responsible for this sequela remains unclear, molecular mimicry between the M protein of rheumatogenic strains of *S. pyogenes* and heart tissue is thought to initiate the autoimmune attack.

Acute Rheumatic Fever

One reason strep throat infections are aggressively treated with antibiotics is because they can lead to serious sequelae, later clinical consequences of a primary infection. These include:
 - Acute Rheumatic Fever
 - Acute Glomerulonephritis

*Streptococcus pyogenes* causes several infections, including: 
 - Streptococcal Pharyngitis (strep throat)
 - Scarlet fever
 - Acute Rheumatic Fever
 - Acute Glomerulonephritis

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Streptococcal pharyngitis, commonly known as strep throat, is an infection of the throat and tonsils caused by *Streptococcus pyogenes.*

Streptococcal Pharyngitis (strep throat)

Scarlet Fever consists of a disseminated fine red rash on the skin, and strawberry tongue, a red rash on the tongue. Severe cases may even lead to streptococcal toxic shock syndrome (STSS), which results from massive superantigen production that leads to septic shock and death.
