Although we now understand that viruses are the most abundant organisms on Earth, there are gaps in our knowledge about their distribution in different environments. Results of a new study reveal the diversity and distribution of viruses in Arctic fresh waters. Read More
The discovery of bi-allelic mutations in RORC in patients with candidiasis and mycobacteriosis revealed the pivotal role of RORC in mucocutaneous immunity to Candida and in systemic immunity to Mycobacterium in humans. Read More
I'm sorry, I may have missed something, but the mechanism behind an effective vaccine is still unclear to me, since infection with F. tularensis does not confer protection. How would a vaccine work?
