Takeaway

  • Pets and their owners have multidrug-resistant (MDR) Enterobacteriaceae species in their stool samples, according to preliminary findings presented at ASM Microbe 2019.
  • Early analyses suggest that about a fifth of people and pets have positive samples. 

Why this matters

  • Antibiotic resistance associated with household pets could be a factor in infection control and a consideration for people with immune compromise. 

Key results

  • At enrollment, 17% of humans and 5% of pets had samples positive for MDR Enterobacteriaceae.
  • At later study visits, the overall rate of positivity at any point was 22% for people and 20% for pets.
  • The study is still enrolling both people and pets.

Study design

  • The study is enrolling healthy pet owners and people with a recent MDR Enterobacteriaceae infection with or without companion animals.
  • Stool is collected at enrollment and at 2, 6, and 12 months later.

Limitations

  • Results are from a preliminary analysis of a still-enrolling study and were presented without peer review at a conference.
