The combination of Demodex folliculorum and Aerobic Bacteria in the Etiopathogenesis of Chronic Blepharitis

Abstract
 Aims: This study was conducted to investigate the presence of thecombination Demodex folliculorum and aerobic bacteria in patients with chronic blepharitis.
 Material Methods: Seventy-one diagnosed blepharitis were evaluated for D. folliculorumby light microscope examination samples prepared from eyelashes collected by eyelash epilation. Culture also obtained patients’ eyelid margins. Bacterial strainsamong predominant bacterial colonies grown cultures identified using BD Phoenix identification system (BD Diagnostic Systems, Sparks, USA). Patients divided into two groups, Demodex-positive Demodex-negative,and compared according production strains produced.
 Results: folliculorumwas 42 (59.1%) patients. Comparison between -negative groups revealeda statistically significant increase positivity age.There no relationship gender positivity.The group showed a significantly higher growth culture than Demodex-negative group.Both exhibited predominance ofStaphylococcus epidermidis. S.epidermidis (38.1% vs. 31.0%), Staphylococcus aureus (19.0% 10.3%), Corynebacterium spp.(16.7% 6.9%) detected at rates group. There difference both regarding these species.
 Conclusions: could have mixedinfection site combination folliculorumand found normal flora.
