Gut bacteria may play role in immune recovery of HIV patients
An international study coordinated by Spanish research institutes has found that gut bacteria also play their role in the immune recovery of HIV patients. Researchers from the University of Valencia (UV) have taken part in a study analysing the influence of gut bacteria on immune recovery in HIV-infected patients undergoing antiretroviral treatment (ART). They have discovered a correlation between immune recovery and the behaviour of a certain subset of gut bacteria in reponse to treatment. Interestingly, this behaviour appears to be both a consequence and a cause of recovery. The implications of this finding are that new complementary therapies could be developed that target these bacteria to

Microbes and you: a partnership millions of years old
We are not alone. Our bodies are teeming metropolises of microscopic life - and the microbes that call us home influence everything from bowel to brain. Over the past decade, technological advances in the lab have allowed us to take a census of our microbial entourage - known as the microbiota - like never before. Instead of seeing only the small fraction of microbes from our skin or poo that blossom on a petri dish, we can now blend, extract and read the genetic essence - the DNA - of all microbes, called the microbiome, to get a better idea of who’s there. The picture that has emerged is one of staggering complexity. From nostrils to armpits, wisdom teeth to bowels, lungs to vaginas, unique
