Rising bacterial resistance to common antibiotics in Al Ain, United Arab Emirates

ABSTRACT

There is a dearth of local information in Al Ain, United Arab Emirates about antibiotic resistance patterns. In this retrospective study in a tertiary referral hospital, antibiotic susceptibility results were analysed over the 5-year period 2004-08 and compared with a previous study in the same hospital during 1999-2002. Staphylococcus aureus showed a significant decrease in sensitivity to oxacillin from 95.0% in the period 1999-2002 to 84.4% in 2008. Sensitivity of Acinetobacter spp. to imipenem dropped from 99.0% in 2004 to only 32.5% in 2008. During the same period, almost half of Escherichia coli isolates developed resistance to cefotoxime. Significant reductions in sensitivity to Pseudomonas aeruginosa between 1999 and 2008 were found for almost all the antibiotics tested. Klebsiella spp. did not show any significant change in resistance to any of the tested antibiotics. Serious efforts are needed to reduce the risk of the spread of resistant strains of bacteria
