[Intestinal Microbiota in Migrating Barn Swallows around Osaka].

In this study, we characterized the fecal bacterial community in barn swallow. Using 16S rRNA gene metagenomic sequencing analysis, we examined the presence and composition of potentially pathogenic bacteria in the fecal samples, which were collected during spring season from Osaka. The number (±S.D.) of total bacteria was approximately 2.1(±3.4)×108 per gram of feces. In most samples, the bacterial community composition was dominated by families, such as Enterobacteriaceae, Pseudomonadaceae, Mycoplasmataceae, Enterococcaceae, Streptococcaceae, and Alcaligenaceae. However, no relationship was found between the bacterial community composition and geographical area in the fecal samples. Potentially pathogenic bacteria were detected at the rate of >0.1%, which included Pseudomonas spp., Escherichia/Shigella spp., Enterobacter spp., Yersinia spp., Mycoplasma spp., Enterococcus spp., Achromobacter spp., and Serratia spp. Our results suggested that barn swallow is instrumental in the transmission of these genera over large distances.
