Abstract

Fourty samples of commonly used eye drops were collected from The Egyptian Pharmacies and divided into 2 groups: group A (with antimicrobial activity) and group B (without antimicrobial activity), the two groups cultured on blood agar medium and Sabouraud agar medium two times after opening these samples in open air, 9 samples showed microbial growth. The number of colonies counted and the organisms isolated and identified as (Staphylococcus auereus, Micrococcus, Candida albicans, and coagulase negative Staphylococcus). After that group (A) samples were taken and inoculated with saline containing Candida albicans and Staphylococcus auereus then they cultured on the same two media, after the period of incubation Candida show growth in all samples while Staphylococcus auereus show positive growth in four samples.
