Mythbuster: The idea that bacterial collaborations within microbiomes, like in the mouth, have evolved to be generous and exclusive very much appears to be wrong. In an extensive experiment, lavish collaborations ensued between random microbes. And some bacteria from the same microbiome were stingy with one another.
The National Institutes of Health has awarded a $2.5 M grant over five years to advance the clinical potential of bacteria-killing viruses to treat antibiotic-resistant infections. Joshua Weitz of the School of Biological Sciences and Justin Debarbieux of Institut Pasteur will lead teams in the U.S. and France to research the interaction between bacteriophage, bacteria, and the innate immune response to enable use of phage therapy even with patients with impaired immune systems.
Some animals that can’t manufacture their own chemical weapons feed on toxic organisms and steal their chemical defenses, having evolved resistance to them. One animal that does this is a sea slug that lives on the reefs surrounding Hawaii and dines on toxic Bryopsis algae. Marine scientists suspected the toxin is made by a bacterium that lives within the alga but have only just discovered the species responsible and teased apart the complex relationship between slug, seaweed, and microbe.
An international group of microbiologists, including Georgia Tech's Frank Stewart, is warning that as science tries to search for climate-change solutions, it’s ignoring the potential consequences for climate change’s tiniest, unseen victims – the world’s microbial communities.
