Summary
This study identified common bacterial and fungal pathogens in ocular infections at a Tehran hospital. Fusarium, Aspergillus, Candida, Pseudomonas aeruginosa, and Staphylococcus were the most frequent culprits.
Area of Science:
- Ophthalmology
- Microbiology
- Infectious Diseases
Background:
- Ocular infections pose a significant threat to vision.
- Identifying causative pathogens is crucial for effective treatment.
- Farabi Eye Tertiary Referral Hospital in Tehran, Iran, is a key center for eye care.
Purpose of the Study:
- To determine the prevalence of bacterial and fungal pathogens in ocular infections.
- To analyze the spectrum of microorganisms causing eye infections in the region.
- To provide data for guiding antimicrobial therapy and infection control.
Main Methods:
- A retrospective analysis of 16,656 ocular specimens collected between 2011 and 2018.
- Specimens were obtained from patients suspected of having ocular infections.
- Microbiological culture and identification techniques were employed.
Main Results:
- Corneal specimens were the most frequently submitted (49.24%).
- Commonly isolated fungi included Fusarium spp., Aspergillus spp., and Candida albicans.
- Leading bacterial pathogens were Pseudomonas aeruginosa, Staphylococcus epidermidis, and Streptococcus pneumoniae.
Conclusions:
- Fusarium, Aspergillus, and Candida are primary fungal causes of ocular infections.
- Pseudomonas aeruginosa, Staphylococcus epidermidis, and Streptococcus pneumoniae are key bacterial pathogens.
- Corneal infections are a major focus for microbiological investigation in ophthalmology.
