God morgon!

Good morning from Sweden.

Today’s digest starts with a super interesting preprint on COVID-19 where the researchers have shown that anti-COVID-19 drugs induce lytic reactivation of an oncogenic virus. As if COVID-19 wasn’t dangerous enough, its treatment is now even more dangerous!

New research has revealed numerous genera of bacteria associated with Amoebozoa, which haven’t been looked into; polyamines as new substrates for a previously known efflux pump in Acinetobacter; genomic differences between the influenza viruses causing infections of different severity; and novel interactions between mycorrhizal fungi and plants.

Hope you’ll enjoy today’s digest!

Hello again everyone! Another change of seasons is upon us and I hope you all remain safe with the upcoming flu season as well as with the continuing covid-19 pandemic. Remember to continue hand washing, social distancing and masking to protect those most vulnerable. Todays post includes more interesting work relating to the gut microbiome with respect to obesity and also as a marker for the disease activity and therapeutic outcome in Inflammatory Bowel Disease. Enjoy!
