Surveying causative agents of infections and their antibiotic resistance pattern is important for policy
making in health systems. Today, antibiotic resistance among ocular pathogens is increasing. Among
these, staphylococcus is an important nosocomial pathogen distributed extensively across the world. In
this work, 300 ocular infection samples are collected from patients in Ghaem hospital. Bacterial specimens
are isolated and identified at genus and species level by laboratory tests. The antimicrobial susceptibility
test is performed for all samples using standard disc diffusion method. Our results show that the most
common bacteria causing ocular infection are Coagulase-Negative Staphylococci and K.pneumonia, and
they are resistant against antibiotics. Due to the fact that the most samples are isolated from neonatal
department as well as the most common bacterium that causes ocular infection is CoNS, it could be
concluded that prenatal or contaminated hands are the first candidates for being responsible for bacteria
transition.
