This study developed a microbial source tracking database for veterinary settings. DNA sequencing identified aquatic, human, and animal sources contributing to restroom microbial communities, aiding contamination source investigation.
Area of Science:
- Microbiology
- Veterinary Science
- Environmental Health
Background:
- Microbial contamination in veterinary facilities poses risks.
- Accurate source tracking is crucial for infection control.
- Existing microbial databases may lack specificity for veterinary environments.
Purpose of the Study:
- To develop and validate a microbial source tracking database for veterinary settings.
- To investigate microbial communities in veterinary facility restrooms.
- To identify potential sources of bacterial contamination.
Main Methods:
- 16S rDNA amplicon sequencing of restroom surfaces.
- Development of a locally curated, metadata-enriched source tracking database.
- Linking microbiota profiling with database analysis for source identification.
Main Results:
- Dominance of Actinobacteria, Bacteroidetes, Proteobacteria, and Firmicutes phyla.
- Significant differences in bacterial distribution between male and female users.
- Identification of aquatic, human, and various animal sources (bovids, insects, equids) linked to specific bacterial genera.
Conclusions:
- DNA sequence-based source tracking is effective for microbial investigations in veterinary settings.
- The developed database aids in identifying known and unknown bacterial contamination sources.
- Further research is needed to explore the tool's broader utility.
