What is the most commonly used prophylactic agent against bacterial conjunctivitis caused by Neisseria gonorrhoeae and Chlamydia trachomatis?

• A. Erythromycin
• B. Clindamycin
• C. Azithromycin
• D. Tetracycline

Answer: (A)

The most commonly used prophylactic agent against bacterial conjunctivitis caused by Neisseria gonorrhoeae and Chlamydia trachomatis is erythromycin. This prophylactic treatment is particularly significant for newborns, as they are at risk for developing conjunctivitis after exposure to these pathogens during delivery. Erythromycin is effective against both organisms and is typically administered as an eye ointment shortly after birth to help prevent eye infections. Erythromycin's broad-spectrum antibiotic properties make it suitable for this purpose, as it can effectively target the specific bacteria that cause conjunctivitis in neonates, leading to a decrease in the incidence of these infections. The choice of erythromycin aligns with guidelines that recommend prophylactic treatment for newborns at risk of infection from maternal transmission during childbirth. In contrast, other antibiotics like clindamycin, azithromycin, and tetracycline may have their own therapeutic applications, but they are not the standard choice for prophylaxis against bacterial conjunctivitis in neonates caused by these specific pathogens.
