Happy Friday! Today’s microbiome digest is a grab bag of articles on topics such as antibiotic cycling and bacterial contamination in surgery, phage isolated from diseased seafood, and microbial communities in snuff. I was particularly interested to see the article focused on degradation genes found in steel industrial soil communities. Finally, I enjoyed checking out two preprints on oral microbiota in Agta, a group of hunter-gatherers from the Philippines.
