Antimicrobial drug susceptibility of bacteria isolated from disease processes in cattle, horses, dogs and cats.
Abstract: Results are presented of antimicrobial disc diffusion susceptibility testing on commonly isolated bacterial pathogens made at the Ontario Veterinary College Diagnostic Bacteriology Laboratory in 1981 and 1982. Nearly 2 000 isolates from horses, cattle, dogs and cats were tested. Comparison of resistance in the same bacterial species isolated from different animal species showed significant differences between some of the same antibiotics.

This research paper reports on a study assessing the effectiveness of certain antimicrobial drugs on bacteria that cause diseases in diverse animal species, namely cattle, horses, dogs, and cats, with the results showing significant variances in drug resistance among the same bacterial species from different animals.
Research Context
- The research was conducted at the Ontario Veterinary College Diagnostic Bacteriology Laboratory in the years 1981 and 1982.
- The scientists used the method of antimicrobial disc diffusion susceptibility testing, a common laboratory technique for the detection of bacterial resistance to antibiotics. This approach entails placing bacteria on a plate with discs containing different antibiotics, which then diffuse into the surrounding agar. The resulting area of growth inhibition gives an indication of the bacteria’s sensitivity or resistance to the given antibiotic.
Sample and Analysis
- The researchers analyzed around 2,000 bacterial isolates — pure samples of bacteria — retrieved from four different types of animals: horses, cattle, dogs, and cats.
- The purpose of testing these diverse isolates was to compare the effectiveness of the same antibiotics on identical bacterial species within the four different host species.
- The principal outcome was to identify any significant differences in resistance to the same antibiotics among the same bacterial species but derived from different animal species.
Findings
- Results indeed revealed notable differences in the resistance of the same bacterial species taken from different animal species to the same antibiotics.
- Such outcomes imply that antibiotic effectivity can vary depending on the host species, a crucial consideration for veterinary drug prescription.
Implications
- The study’s conclusion offers valuable insights for the veterinary community in choosing the best-suited antibiotic treatments for different host animals.
- Findings also emphasize the importance of constant monitoring of antibiotic resistance as it can fluctuate within and across species. This is essential for effectively controlling and treating bacterial infections in veterinary practice.
