Bonjour from Paris, France !

In today’s digest you will find a broad range of amazing preprints and published papers! An amazing read is a fresh preprint from Fritz and collaborator describing an exciting method of sampling in difficult to reach environments. The authors used army ants of the genus Dorylus which are foragers to survey the viral diversity of plants, vertebrate and invertebrates of the tropical forest!

Today’s non-microbiology pick is an opinion piece on the current state and limitation of viral taxonomy. In this piece, Simmonds and collaborators, provide concrete recommendations to guide the development of a coherent and comprehensive virus taxonomy.

Have a great Saturday!
