Which group of streptococci is known for producing erythrogenic toxins?

• A. Group A
• B. Group B
• C. Group C
• D. Group G

Answer: (A)

Group A streptococci, primarily Streptococcus pyogenes, are known for producing erythrogenic toxins. These toxins are responsible for some of the key symptoms associated with conditions like scarlet fever, where the classic rash and fever are prominently observed. The presence of erythrogenic toxins contributes to the pathogenicity of Group A streptococci, allowing them to induce an inflammatory response, leading to clinical manifestations. The ability of these bacteria to produce such toxins is a significant factor in their virulence, differentiating them from other groups. Other groups, such as Group B, Group C, and Group G streptococci, do not typically produce erythrogenic toxins and are associated with different clinical conditions and pathogenic mechanisms. Understanding the role of these toxins in infectious disease provides essential insights into the mechanisms by which Group A streptococci cause illness.
