Resumen

Introduction: Vancomycin resistant and multi-drug-resistant enterococci are the major emerging pathogens in surgical, neonatal, and tertiary care units. Methodology: In this study, 267 enterococci from different clinical and non-clinical samples of equine origin were tested for their antimicrobial drug sensitivity against 19 antimicrobials using disc diffusion method. Results: A total of 80.2% enterococci tested were resistant to vancomycin and 99.6% to multiple-drugs. There was a significant association between haemolytic potential and vancomycin resistance (χ², 0.00). Enterococci isolates from healthy equids were significantly (χ², 0.04) less resistant to vancomycin than the isolates from clinically sick animals. Besides vancomycin sensitivity, isolates were also tested for 18 more antimicrobial drugs; maximum numbers of isolates were sensitive to imipenem (75%) followed by tetracycline (60%), amoxicillin+clavulanic acid (54%), and minimum for cefdinir (4%). Conclusion: More than 80% strains of enterococci of equine origin were found resistant to vancomycin and 99.6% were multiple-drug resistant in Northern India. High prevalence of VRE and MDRE in healthy equids might be a potential danger for the health of persons in equine contact.
