Hypothesis
What are the phenotypic and genetic characteristics of antimicrobial-resistant E. coli isolated from puppies in kennels?
Conclusion
Puppies in kennels can carry multidrug-resistant E. coli, and these bacteria can spread clonally among different litters.
Supporting Evidence
- 76% of E. coli isolates were resistant to one or more antimicrobials.
- 60.5% of isolates showed multidrug resistance.
- The prevalence of resistance varied significantly between the two kennels.
Takeaway
This study found that puppies in kennels can get sick from bacteria that are hard to treat with medicine, and these germs can spread between puppies.
Methodology
Faecal samples from 43 puppies were tested for antimicrobial resistance using various methods including agar dilution and pulsed-field gel electrophoresis.
Limitations
The study did not account for potential exposure of pups to antimicrobials through their mothers' milk.
Participant Demographics
Puppies from two kennels, aged not above two months.
