And it is (finally) accepted to be published in Microbiology Spectrum.
Our work on the sulfonamide resistance gene, sul4, is (finally) available as preprint. Thanks to an excellent PhD student Melina Markkanen. Hopefully soon it will be also peer-reviewed and published. After the first desk rejection, we are looking for another journal.

Sulfonamide resistance gene sul4 is hosted by common wastewater sludge bacteria and found in various newly described contexts and hosts including clinically relevant species
The introduction of the first broad-spectrum antibiotics, sulfonamide drugs fundamentally revolutionized medicine in the 1930s. Shortly after and ever since sulfonamide resistance genes (sul genes) ha...
