Streptococci form long chains and can cause which infection?

• A. Strep throat
• B. Tuberculosis
• C. Cholera
• D. Athlete's foot

Answer: (A)

Streptococci arranged in long chains are a classic clue pointing to infections of the throat, most notably strep throat. When these bacteria colonize the tonsils and pharynx, they cause pharyngitis with symptoms like painful swallowing, fever, and swollen lymph nodes. The other conditions listed come from entirely different organisms: tuberculosis from Mycobacterium tuberculosis, cholera from Vibrio cholerae, and athlete’s foot from fungi. So the infection most characteristically linked to streptococci in chains is strep throat.
