Generation of equine‐specific local antibiograms: reproductive tract of mares and fillies in Western Australia

Gram-negative isolates were most susceptible to the high importance antimicrobials ceftiofur and enrofloxacin. However, these antimicrobials should be used judiciously only after culture and sensitivity testing have been performed, in accordance with the Australian Veterinary Prescribing Guidelines, as part of AMS. This study found that Gram-negative organisms are most susceptible to first-line empirical treatment with tetracycline if E. coli is suspected, or gentamicin when in doubt. Gram-positive isolates were most susceptible to first-line empirical treatment with ampicillin, penicillin or TMS. Regular updates to the antibiogram are required to provide contemporary empirical guidance for the use of antimicrobials.
