Abstract

We evaluated the distribution of normal conjuctival flora and the change of antibiotic sensitivity of cultured bacteria. Specimens were obtained from inferior conjunctiva cul de sac with sterile cotton-tipped applicator from healthy 216 human beings. Antibiotic sensitivity test was done by disk diffusion method. The results indicated that overall positive culture rate was 47.7% and major organisms were Coagulase-negative Staphylococcus(55.7%), Staphylococcus aureus(16%), Gram negative bacteria(7.5%), Streptococcus(4.7%). Antibiotic sensitivity test of cultured Gram positive bacteria demonstrated less than 60% rate of susceptability in gentamicin, tetracyclin, erythromycin and 80.5% rate of susceptability in ciprofloxacin. Gram negative bacteria demonstrated less than 60% rate of susceptability in cephalothin, ampicillin. From the above results, we concluded that antibiotic resistance of normal conjunctival flora was increased from the past and the principle of antiviotic eye drop use should be emphasized.
