A rare case of infantile acute polymicrobial dacryocystitis due to Serratia marcescens, Haemophilus aphrophilus, and Prevotellaintermedia.

Infantile acute dacryocystitis is an acute inflammation of the lacrimal sac in infants. The most common pathogens are Gram-positive cocci and Gram-negative rods. We report a case of infantile polymicrobial acute dacryocystitis. A 6-week-old girl presented emergently with eye edema, discharge, and fever. Symptoms resolved with nasolacrimal probing and systemic antibiotics. Intraoperative cultures were positive for Serratia marcescens , Haemophilus aphrophilus , and Prevotella intermedia. This case highlights the importance of considering uncommon pathogens in the etiology of infantile dacryocystitis. [ABSTRACT FROM AUTHOR]
