Ocular infections are common and vary from self-limiting to sight-threatening. All the structures of the eye can be infected by various microbes.The present study was undertaken to determine the prevalence of bacterial and fungal infections of the eye and also to assess the antibiotic susceptibility pattern of bacterial isolates at an eye care hospital in Bangalore, India. Two hundred thirty five samples were received from infections of the eye-conjunctivitis including dacrocystis, corneal ulcers, endophthalmitis and post-traumatic infections. Culture, Gram's stain and potassium hydroxide (KOH) mount was done for allclinical specimens. Giemsa staining was done occasionally as required. Antibiotic susceptibility testing was performed for bacterial growth. Out of 235 samples processed, 81(34.5%) yielded bacterial growth and 32 (13.6%) yielded fungal growth. One corneal scraping showed the presence of Acanthamoeba by microscopy. Predominant bacterial isolates were-Staphylococcus sp...

Bacteriology and antimicrobial susceptibility pattern of external ocular infections in rural tertiary care teaching hospitalBackground: This study was aimed at determining the prevalence of external ocular infections and susceptibility profile of associated bacteria along with special reference to methicillin-resistant Staphylococcus aureus (MRSA). Materials and Methods: During the study period, 227 ocular samples were collected from patients clinically diagnosed with external ocular infections such as conjunctivitis, keratitis, and blepharitis. All samples were processed for direct microscopy, culture and identification by standard methods. Susceptibility testing was done by Kirby-Bauer method as per Clinical and Laboratory Standard Institute (CLSI) guidelines. Methicillin resistance was determined by cefoxitin disc diffusion method. All the analysis was performed using simple percentage method Results: Out of 227 ocular specimens, 158 specimens yielded significant bacterial growth. The isolation rate was 70.54% in conjunctivitis (91 of 129), 77.05% in keratitis (47 of 61) and 54.05% in blepharitis (20 of 37). Newborn to under two years of age group recorded highest cases 73(46.20%). The predominant bacterial species isolated was staphylococcus aureus 39 (27.4%) followed by Pseudomonas aeruginosa 35 (22.15%). Overall prevalence of methicillin-resistant Staphylococcus aureus was 5 (12.82%). All Gram positive cocci were susceptible to vancomycin including methicillin-resistant Staphylococcus aureus. All Gram positive cocci and Gram negative bacilli showed good response towards amikacin and moxifloxacin in a range of 60-100%.Apart from vancomycin, all methicillin-resistant Staphylococcus aureus isolates remained susceptible to chloramphenicol. Conclusion: Gram-positive cocci were the most frequent bacteria isolated from ocular infections and were sensitive to moxifloxacin and vancomycin, while gram negative isolates were more sensitive to amikacin.

A study of bacterial isolates from corneal specimens and their antibiotic resistance profile2006 •
We aim to examine the spectrum of bacteria causing corneal infections and their antibiotic susceptibility patterns. This will serve as a guideline for empiric therapy of corneal infections. We conducted the study over a period of 18 months from March 2001 through December 2002 in King Abdul-Aziz University Hospital, Riyadh, Kingdom of Saudi Arabia. Corneal specimens taken from 200 patients were inoculated directly onto different types of media. The isolates were identified and then tested against the appropriate topical or systemic antibiotics. Sixty-seven (33.5%) of the total specimens were culture positive and 133 (66.5%) were culture negative. Fourteen (7%) of these showed organisms in the Gram stained smears and correlated well with the culture reports. Of the 67 positive cultures, 53 (79.1%) were Gram-positive bacteria mostly coagulase-negative Staphylococci 29 (43.3%) followed by Streptococcus pneumoniae (S. pneumoniae) 13 (19.4%). Among Gram-negative bacteria 14 (20.9%), Pseu...

The Prevalence of Bacteria, Fungi, Viruses, and Acanthamoeba From 3,004 Cases of Keratitis, Endophthalmitis, and Conjunctivitis2019 •
Purpose: The definitive identification of ocular pathogens optimizes effective treatment. Although the types of ocular pathogens are known; there is less definitive information on the prevalence of causative infections including viruses, fungi, and protozoa, which is the focus of this retrospective laboratory review. Methods: Data used for laboratory certification were reviewed for the detection of bacteria, viruses, fungi, and protozoa, from patients with infectious keratitis, endophthalmitis, and conjunctivitis. The main outcome parameter was laboratory-positive ocular infection. Results: The distribution of infectious agents for keratitis (n=1,387) (2004–2018) was bacteria 72.1% (Staphylococcus aureus 20.3%, Pseudomonas aeruginosa 18%, Streptococcus spp. 8.5%, other gram-positives 12.4%, and other gram-negatives 12.9%), Herpes simplex virus 16%, fungi 6.7%, and Acanthamoeba 5.2%. For endophthalmitis, (n=770) (1993–2018), the bacterial distribution was coagulase-negative Staphyloc...
Abstract: Background: Ocular infections are one of the common diseases of the eye. The current trends in the etiology of ocular infections and their antibacterial susceptibility pattern must be updated to help the clinicians. Objective: To identify the aerobic bacterial profile of ocular infections in patients attending Ophthalmology OPD/IPD. Materials and Methods: 102 patients attending Ophthalmology OPD/IPD in Navodaya Medical College Hospital & Research Centre were analysed from Nov 2010 to Sep 2011. Using predefined inclusion and exclusion criteria, samples were collected according to the standard protocol. These were cultured for microorganisms ( aerobic bacterial ) were identified. Drug susceptibility was done using Kirby Bauer disc diffusion method. Results: The most common bacterial pathogen isolated were Staphylococcus aureus(32.8%) followed by Staphylococcus epidermidis (25%),other organisms isolated are Streptococcus pneumonia (14.1%), Kiebsiella pneumonia (6.3%), Escherichia coil (4.7%). Bacterial isolates were highly susceptible to Vancomycin(100%), Gentamicin(94.3%) among Gram positive organisms and among Gram negative organisms it is highly susceptible to Tobramycin(100%) and Imipenem(90.9%). Conclusion: The study suggest that Staphylococcus aureus and Staphylococcus epidermidis are the most common etiological agents of Ocular infections. Most of the strains were sensitive to Vancomycin and Tobramycin. Keywords: Ocular infections, Staphylococcus aureus, Staphylococcus epidermidis, Vancomycin, Tobramycin.

Bacterial Profile and Antimicrobial Susceptibility Pattern of External Ocular Infections in Jimma University Specialized Hospital, Southwest Ethiopia2013 •
Bacteria are the major etiologic agents causing external ocular infections. Resistance of ocular bacteria to antimicrobial agents is a worldwide concern. In this study we sought to determine the bacterial profile and antibiotic susceptibility pattern of external ocular infections patients attending Jimma University Specialized Hospital, Southwest Ethiopia. A cross-sectional study design was employed from January 2012 to June 2012 from which a total of 198 patients with external ocular infections were included in the study. The samples thus collected were transported and are microbiologically processed using standard operating procedure (SOP) under standard laboratory conditions. The data acquired was analysed by computer for statistical analysis using SPSS version 16 for Windows. A total of 198 ocular samples were collected for microbiological evaluation, of which 148 (74.7%) had bacterial growth. The gram-positive cocci comprised 52.0% and the predominant isolate was S. aureus (28.4%). Gram-negative bacteria accounted for 48.0% and the predominant isolate was P. aeruginosa (20.9%). Majority of gram-positive cocci were susceptible to ciprofloxacin (71; 92.2%) and vancomycin (70; 90.9%) and gram-negative isolates to amikacin (67; 94.4%) and ciprofloxacin (57; 91.5%). These findings indicated that gram-positive cocci were the most common bacteria isolated from external ocular infections and were more susceptible to ciprofloxacin and vancomycin, whereas gram-negative isolates were more susceptible to amikacin and ciprofloxacin.
