Viruses that can target and destroy bacteria have the potential to be an effective strategy for tackling hard-to-treat bacterial infections. The development of such novel therapies is being accelerated in response to growing antibiotic resistance, says Dr David Harper at the Society for General Microbiology's Spring Conference in Dublin. Bacteriophages are viruses that can infect bacteria and multiply within them, breaking down the cell and destroying the bacteria - amplifying themselves...

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...

New discovery bonds to anthrax spores, not just anthrax bacteria A new study has shown previously unseen details of an anthrax bacteriophage – a virus that infects anthrax bacteria – revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents. The bacteriophage, known as Bacillus anthracis spore-binding phage...

New research in the FASEB Journal suggests that site-specific recombinases from either yeast or phages act not only to tag and target but also to exchange specific genes in DNA A combination of two techniques promises to improve the efficiency and effectiveness of experimental gene therapies, while also reducing potential side effects says a new research report published in the December 2011 issue of the FASEB Journal (http://www.fasebj.org). The report describes how scientists from...

Pseudomonas deploys a toxin delivery machine to breach cell walls of rivals without hurting itself Microbiologists have uncovered a sneaky trick by the bacterium Pseudomonas aeruginosa to oust rivals. It deploys a toxin delivery machine to breach cell walls of competitors without hurting itself. Its means of attack helps it survive in the outside environment and may even help it cause infection. P. aeruginosa is a common bacterium that lives in soil, and also an opportunistic pathogen best...

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...

Recently a research paper titled "Expanding the Diversity of Mycobacteriophages: Insights into Genome Architecture and Evolution" was published in PLoS ONE, a peer-reviewed online journal published by the Public Library of Science. The authors included 12 Washington University undergraduates who had participated as freshman in the inaugural Phage Hunters course at Washington University in St. Louis. Phages are viruses that infect bacteria by injecting genetic material into them with a...

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...
