Antimicrobial resistance in bacteria isolated from horses from the Atlantic Provinces, Canada (1994 to 2013).

Abstract: This study determined the antimicrobial susceptibility patterns and trends for selected bacteria isolated from horses using diagnostic data from the Atlantic Veterinary College Diagnostic Services Bacteriology Laboratory, Charlottetown, Prince Edward Island over a 20-year period. subsp. and were the most commonly isolated bacteria over the study period. Clinical samples were most frequently submitted from respiratory and reproductive systems. Most bacterial isolates were susceptible to ceftiofur. Resistance was most common in Gram-negative enteric bacteria, while streptococci were frequently susceptible to most of the antimicrobials tested including penicillin and trimethoprim-sulfamethoxazole. The antimicrobial resistance trends over the study period were relatively stable. Multi-drug resistance was observed in 9% of the bacterial isolates. Information provided in this study could be used to help guide rational, empirical antimicrobial treatment selection in equine practices in Atlantic Canada. Cette étude a déterminé les modèles et les tendances de susceptibilité antimicrobienne pour certaines bactéries isolées des chevaux en s’appuyant sur des données diagnostiques du Laboratoire de bactériologie des services diagnostiques de l’Atlantic Veterinary College à Charlottetown, à l’Île-du-Prince-Édouard, pendant une période de 20 ans. ssp. et ont été les bactéries les plus communément isolées pendant la période à l’étude. Des échantillons cliniques des systèmes respiratoires et reproducteurs étaient les plus fréquemment soumis. La plupart des isolats bactériens étaient susceptibles au ceftiofur. La résistance était la plus courante chez les bactéries entériques à Gram négatif, tandis que les streptocoques étaient fréquemment susceptibles à la plupart des antimicrobiens testés incluant la pénicilline et le triméthoprime-sulfaméthoxazole. Les tendances de résistance aux antimicrobiens pendant la période à l’étude étaient relativement stables. Une multirésistance aux médicaments a été observée dans 9 % des isolats bactériens. Les renseignements fournis dans cette étude pourraient servir à guider un choix rationnel et empirique pour les traitements antimicrobiens dans les pratiques équines des provinces de l’Atlantique.(Traduit par Isabelle Vallières).

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article studies the resistance patterns and trends of selected bacteria isolated from horses over a span of 20 years in the Atlantic Provinces, Canada.

Objective of Research

  • The main objective of the research was to understand the antimicrobial susceptibility patterns and trends of certain bacteria isolated from horses. This data was sourced from the Atlantic Veterinary College Diagnostic Services Bacteriology Laboratory in Charlottetown, Prince Edward Island, and spans over 20 years.

Findings of Study

  • The research reveals that Streptococci and Gram-negative enteric bacteria were the most common types of bacteria isolated over the 20 year study period.
  • The clinical samples that were analysed primarily came from the respiratory and reproductive systems of the horses.
  • The majority of these bacterial isolates were susceptible to the antibiotic, ceftiofur.
  • Resistance was eminent mostly in the Gram-negative enteric bacteria, while streptococci were susceptible to most of the antimicrobials that were tested. This includes penicillin and trimethoprim-sulfamethoxazole.
  • Over the course of the study, the antimicrobial resistance patterns were relatively stable.
  • The research also discovered that multi-drug resistance was present in about 9% of the bacterial isolates.

Significance of Research

  • In conclusion, the study is of significant value as it compiles information on the susceptibility and resistance patterns in bacteria found in horses from the Atlantic Provinces over a 20-year period.
  • This study provides crucial information that can aid in a more rational and empirical selection of antimicrobial treatments in equine practices within the Atlantic Provinces of Canada.
