Abstract

The aim of current study is to characterize bacteria isolated from eye infections and evaluate the effectiveness of some antimicrobials found in eye drops in the Egyptian Market. Clinical bacterial isolates were recovered from patients having conjunctivitis from Benha University Hospital and identified using standard microbiological techniques. Antimicrobial susceptibility of these isolates against various antimicrobials was tested by the disc diffusion method.
A total of eighty one bacterial isolates were identified in this study, 30 Gram positive isolates and 51 Gram negative isolates. The major bacterial isolates were Pseudomonas aeruginosa (37%) and Staphylococcus spp. (37%). All the isolates were susceptible to fluroquinolones, and almost all of them were susceptible to aminoglycoside antibiotics. While 75 isolates were susceptible to tetracycline and 71 isolates were susceptible to chloramphenicol. High resistance rates were observed for both bacitracin (45.7%) and fusidic acid (60.4%). Seven isolates were multidrug resistant (MDR).
This study demonstrated that isolates from infected eye were highly sensitive to fluroquinolones and aminoglycosides. This study recommends that antimicrobial susceptibility should be performed for bacteria isolated
