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

摘要

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 epidermidisand?Pseudomonas aeruginosa?were the most common microorganisms isolated (25.281and?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.
