| Abstract | Bacteria are major cause of ocular infections and possible loss of vision. The emergence of antimicrobial resistant bacteria increases the risk of treatment failure with potentially serious consequences. The aim of this study was to determine the prevalence of bacterial isolates 1 Corresponding author: talfaki@yahoo.com Salah K. A.

A cross-sectional study was conducted among 52 patients with external ocular infections at El-Waledain and Abd Elfadeil Almaz Specified Hospital, Khartoum. Socio-demographic and clinical data were collected using structured questionnaire. The specimens were collected by using sterile cotton swabs and then cultured in blood ager, chocolate agar and MacConkey agar, the identification of isolates done by several biochemical tests, Susceptibility pattern of isolated bacteria to antibiotics done by disc diffusion method. Out of fifty two eye swab specimens investigated, 22(42.3%) from males and 30(57.7%) from females. The overall prevalence of bacterial pathogens among samples were 47(90.4 %(. Bacteriological tests showed that 25 (53.2%) were Gram positive and 22(46.8%) Gram negative bacteria. The frequencies of bacteria appear as; Staphylococcus epidermidis40.8% (n=22/47), Staphylococcus aureus 6.4% (n=3/47), Serratia marcescens 4.3% (n=2/47), and Pseudomonas aerugionsa was 42.6 % (n=20/47). From the above findings we concluded that, the prevalence of bacterial pathogens among eye swab samples was high and the predominant isolate were Staphylococcus epidermidis, Pseudomonas aerugionsa, Staphylococcus aureus and Serratia marcescens respectively. With regard to sensitivity to antibiotics six antibiotics were used; (Tetracycline, Ciprofloxacin, Gentamicin, Chloramphenicol, Tobramycin, Methicillin, Vancomycin, last two one for Staphylococcus aureus only), the result showed that the bacterial isolate were highly suspected to these antibiotics, Staphylococcus aureus strain collected were MRSA and Pseudomonas strain showed resistant to tetracycline which was previously administered as ointment or eye droplets. This study has shown the high percentage of eye infections among patients, so the study recommended that eye infections patients should be subjected to routine eye swab culture and determination of sensitivity to clinical isolates in order to select appropriate antimicrobial agents. |
