Introduction Antimicrobial resistance is an emerging concern in veterinary and human medicine. The present study aims at describing the situation of antimicrobial resistance at the clinic for horses of the University of Veterinary Medicine of Vienna in order to establish prospective evidence-based guidelines for antimicrobial usage in horses.
Material and methods
Bacteriological results and antibiograms performed at the equine hospital (surgery, orthopaedics and internal medicine) of the University of Veterinary Medicine of Vienna between January V, 2007 and June 30(th), 2009 were reviewed. Altogether 1,008 samples yielded 1,323 bacteria, which were subdivided in reference to the occurrence of bacteria per organ system and their antimicrobial resistance. The data were analyzed according to their frequency distribution with IBM (R) SPSS (R) PASW Statistics 18 and Microsoft Excel 2007.
Results
Streptococcus sp. was the most common grampositive bacterium and E. coli the most common gram-negative bacterium. Individual drug resistance of the isolates ranged from a minimum of 2.0 % to a maximum of 98.5 %. High rates of antimicrobial resistance (between 38 % und 93 %) existed for trimetoprim-sulfonamides.
Conclusion
The results confirmed already existing antimicrobial resistance at the equine clinic of the University of Veterinary Medicine of Vienna. The results highlighted the need for preventive procedures in order to control further development of antimicrobial resistance in Austria. Besides hygienic measurements guidelines for responsible antibiotic selection have to be developed. A team of equine veterinarians (practitioners and scientists) has been formed at the University of Veterinary Medicine of Vienna to deal with the situation in Austria.
