Pilot study on antibiotic resistance of conjuctival bacteria - RAGS study

Abstract

The main purpose of this study is to compare the resistance profile of bacteria isolated from conjunctival secretions in our center with that of bacteria isolated in the ARMOR 2013 study. A total of 1591 samples were analyzed, successively collected for 5 years. Of these, 53.5% had a positive result, 37.6% were negative, and 8.9% were contaminated with saprophytic flora, the latter not being included in the statistics. The resistance of Staphylococcus aureus MRSA / MSSA to clindamycin, chloramphenicol and ciprofloxacin obtained in the RAGS study is higher than that recorded in the ARMOR study. The resistance of coagulase-negative staphylococci (MR CoNS / MS CoNS) to tobramycin obtained in our study is higher than that recorded in the ARMOR study, the same being true for chloramphenicol. The resistance of Pseudomonas aeruginosa to tobramycin obtained in the RAGS study is also higher than that recorded in the ARMOR study.
