Which organism is associated with Scarlet fever?

• A. Group B streptococci
• B. Alpha-hemolytic streptococci
• C. Group A streptococci
• D. Enterococci

Answer: (C)

Scarlet fever is caused by an infection with Group A streptococci, specifically the bacteria Streptococcus pyogenes. This organism is known for producing a toxin that leads to the characteristic rash associated with the disease. Group A streptococci are also responsible for other conditions such as strep throat and impetigo, making them significant in clinical bacteriology. In contrast, Group B streptococci are typically associated with infections in newborns and pregnant women, while alpha-hemolytic streptococci are usually part of the normal flora in the human body and can cause various opportunistic infections but are not the cause of scarlet fever. Enterococci, on the other hand, are often implicated in urinary tract infections and other hospital-acquired infections but are not related to scarlet fever. Thus, the accurate association of scarlet fever with Group A streptococci underscores its importance in the realm of infectious diseases.
