Bacteria isolated from contact and non contact lens and antibiotic susceptibility patterns of isolated Pseudomonas aeruginosa

Abstract

The aim of this study was to investigate the prevalence and type of microbial contamination, associated with contact lenses and lens care accessories used by a group of contact lens wearers. Results show that a total of 178 strains were isolated, including, 100 Gram positive and 78 Gram negative bacteria. Staphylococcus epidermidis and Pseudomonas aeruginosa were the most common microorganisms isolated (25.281 and 13.483% respectively. 24 P. aeruginosa were isolated from lenses and eyes of contact lens and non-contact lens wearers. All isolates were susceptible to the tested aminoglycosides and fluoroquinolones. Aminoglycosides and fluoroquinolones (ciprofloxacin) were more efficient than β-lactams. 91.67% of the strains had intermediate-resistant to cefotaximee; 4.17% were resistant and 4.17% were sensitive to Cefotaximee. 95.83% of the strains were sensitive, while 4.17% were resistant to Imipenem. 20.83 and 12.5% of P. aeruginosa strains were resistant and sensitive to Ceftriaxone respectively, while 66.67% were moderately-resistant to ceftriaxone of the β-lactam class. All isolates were sensitive to the other tested β-lactam.

Assessment of Bacterial Contamination on Contact Lenses among Medicos

“…aeruginosa and Acinetobacter spp in the contact lenses. 16 We reported that Pseudomonas aeruginosa was the Klebsiella pneumonie. This is in corroborate with our findings.…”
