Short digest for today, but I’d like to draw attention to two studies on creative techniques to reduce contamination by host DNA sequences: one using PCR blocking primers to improve 16S rDNA sequencing, and the other on using CRISPR-Cas systems to assist with 18S rDNA sequencing. Happy reading!

Among the highlights for today, there’s an unusual preprint on using honeybees for proxy sampling of the urban microbiome, as well as a paper on the effect of captivity on the microbiome of raptors.

In some non-microbiome related news, the summarized highlights from the 5th International One Health Congress were recently published. Some of their recommendations regarding science and public health are particularly apt considering the present pandemic, and I found it to be quite an interesting read. You can find it here:

Good morning and salutations from Singapore! This is the first digest that I’m contributing for the blog, so I hope my selections are interesting to you all! Today’s digest begins with some recent COVID-19 pre-prints, before getting into papers on a diverse range of microbiome-related topics. Highlights today include a study on cats potentially harbouring SARS-CoV-2 (nooo…), the effect of C-section birth on the vaginal microbiota of adult women, and the impact of the virome on biogeochemical cycling in Lake Baikal.
