Resistant Infantile Bacterial Conjunctivitis in Egypt: A Microbiology Study.

PURPOSE: To study the microbiological aspects of infantile bacterial conjunctivitis resistant to empirical topical antibiotic therapy in Egypt.

METHODS

Ninety-two eyes of 86 infants with bacterial conjunctivitis were included in this prospective study. They all failed to show evidence of clinical improvement after 2 weeks of empirical topical antibiotic therapy. Conjunctival swabs were obtained from all patients for bacterial culture and antibiotic sensitivity testing.

RESULTS

The age of the participants ranged from 4 to 6 months. Culture results revealed infection with a solitary organism in 48.9% of eyes. Mixed bacterial growth was reported in 47.8% of eyes, whereas 3.3% of eyes showed no bacterial growth. The most commonly isolated organisms were Staphylococcus aureus, Streptococcus pneumoniae, and Pseudomonas aeruginosa. These organisms were highly sensitive to fluoroquinolones (levofloxacin, ciprofloxacin, ofloxacin, and norfloxacin), followed by chloramphenicol, vancomycin, and amikacin, and were resistant to carbapenems (imipenem and meropenem), fusidic acid, and pipracellin.

CONCLUSIONS

Bacterial culture and antibiotic sensitivity testing provides beneficial diagnostic and therapeutic information when dealing with infantile resistant bacterial conjunctivitis. [J Pediatr Ophthalmol Strabismus. 2018;55(2):135-139.].
