Hypothesis
Dogs have a stable composition of the colon microbial community and that episodes of diarrhea lead to long lasting changes in community composition and/or function.
Conclusion
The study found that dogs' gut microbiota can change significantly during episodes of diarrhea, influenced by diet and medications.
Supporting Evidence
- Healthy dogs had stable gut microbiota, while those in variable environments showed more changes.
- Diarrheic episodes led to significant increases in certain bacteria like Clostridium perfringens.
- Changes in diet and medications resulted in repeated changes in the microbiota of previously stable dogs.
Takeaway
This study looked at how the bacteria in dogs' tummies change when they get diarrhea, showing that their gut health can be affected by what they eat and any medicines they take.
Methodology
The study used terminal restriction fragment length polymorphism (T-RFLP) analysis to assess the stability of fecal microbiota in dogs and changes associated with diarrhea.
Limitations
The study had a small sample size and was conducted in a specific environment, which may limit the generalizability of the findings.
Participant Demographics
The study included eight household pet dogs of various breeds and ages, with some experiencing diarrhea and others serving as controls.
