This epidemiological study was performed to determine the prevalence of Pseudomonas aeruginosa on contact lenses of selected students in Caleb University, Imota, Lagos State. A swab of 100 contact lenses from selected volunteers comprising 43 males and 57 females were collected for microbiological examination. Sterile swab sticks moistened with sterile distilled water were used to aseptically swab the lenses and transferred into nutrient broth followed by incubation for 5 hours. Thereafter, the resultant broth culture was subcultured on to cetrimide nutrient agar and incubated at 370C for 24 hours for the isolation of Pseudomonas aeruginosa. A total of 30 (30%) of the contact lenses sampled were found to have Pseudomonas aeruginosa, of which 13(43.3%) of the isolates were pigmented and 17(56.7%) were non-pigmented. Eighty percent (80%) of the isolates were susceptible to ciprofloxacin, 75% to gentamicin while 50% were susceptible to ofloxacin. The isolates were 90% resistant to nitrofurantoin, 75% resistant to augmentin and 100% to ampicillin. Ciprofloxacin and gentamicin were found to be effective against Pseudomonas aeruginosa in this study and could be of therapeutic relevance for the management of contact lenses mediated infections.enAntimicrobial susceptibilityPrevalenceContact lensesPseudomonas aeruginosaArticle
