cholera and phages

Siobhan Gallagher, Tufts University In the battle between our immune systems and cholera bacteria, humans may have an unknown ally in bacteria-killing viruses known as phages. In a new study, researchers from Tufts University, Massachusetts General Hospital, Partners In Health, Haiti’s National Public Health Laboratory, and elsewhere, report that phages can force cholera bacteria to give up their virulence in order to survive. Importantly, the study — published in eLife — found that...

Glimpse Into Untapped Biodiversity Offered By Newly Discovered Marine Viruses

University of Arizona Studying bacteria from the Baltic Sea, University of Arizona researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown viruses that infect different strains of marine bacteria. Bacteriophages -- viruses that prey on bacteria -- are less familiar to most people than their...

MIT researchers have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts: These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship. The con occurs when a grifter virus injects its DNA into a bacterium living in a phosphorus-starved region of the ocean. Such...

Bacteria are common sources of infection, but these microorganisms can themselves be infected by even smaller agents: viruses. A new analysis of the interactions between bacteria and viruses has revealed patterns that could help scientists working to understand which viruses infect which bacteria in the microbial world. A meta-analysis of the interactions shows that the infection patterns exhibit a nested structure, with hard-to-infect bacteria infected by generalist viruses and...
