Dogs can have a beneficial impact on the microbiome of pediatric patients

In a fascinating study, researchers investigated microbial sharing between therapy dogs and pediatric oncology patients in a hospital environment. The main goal was to explore the potential impact of #therapydogs on the increased patients’ risk of microbial exposure.

Microbial samples were collected from the nasal mucosa of both pediatric patients and therapy dogs before and after each therapy session. High throughput 16S rRNA amplicon sequencing of V1-V3 region was conducted to characterize microbial communities.

Both pediatric patients and therapy dogs exhibited significant changes in the relative abundance and overall diversity of their nasal microbiome, indicating the occurrence of microorganism exchange. In this way, the authors suggest that exposure to therapy dogs has the potential to counterbalance the decrease in microbial diversity caused by specific therapies in pediatric patients.

Moreover, this study proposes that interaction with therapy dogs could be a novel way to mitigate this imbalance and transmit potentially beneficial microorganisms that may offer protection against the colonization and infection of hospital pathogens.
