HZI researchers discover multiple versions of microbial defense genes that lend themselves to being exploited by biotechnology Even bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders — in their case, viruses. Scientists at the Helmholtz Center for Infection Research (HZI) in Braunschweig, Germany, were now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions....

CRISPR, a system of genes that bacteria use to defend themselves against viruses, has been found to be involved in helping some bacteria evade the mammalian immune system. The results are scheduled for publication Sunday, April 14 in Nature. CRISPR is itself a sort of immune system for bacteria. Its function was discovered by dairy industry researchers seeking to prevent phages, the viruses that infect bacteria, from ruining the cultures used to make cheese and yogurt. Bacteria...

A new broad range antibiotic, developed jointly by scientists at The Rockefeller University and Astex Pharmaceuticals, has been found to kill a wide range of bacteria, including drug-resistant Staphylococcus (MRSA) bacteria that do not respond to traditional drugs, in mice. The antibiotic, Epimerox, targets weaknesses in bacteria that have long been exploited by viruses that attack them, known as phage, and has even been shown to protect animals from fatal infection by Bacillus anthracis, the...

Oceans Have Been The Stage For Earth's Longest Ongoing Battle Between Bacteria And A Virus
2013-02-14 13:55:19

April Flowers for redOrbit.com - Your Universe Online A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over. The findings of this study were published in a recent issue of Nature. On one side of the battle lines stands SAR11, a bacterium that´s the most abundant organism in the oceans, surviving where most other cells...

The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in Science Express. To infect a cell, a virus must be able to first find a suitable cell and then eject its genetic material into its host. This robot-like process has been observed in a virus called T7 and...

Common Human Viruses Could Lead To Acne Cure
2012-09-25 10:45:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Acne, Propionibacterium acnes, is a common human skin disease that affects hundreds of millions of people every year. It is also the bane of teenagers, causing insecurity and disrupting social life for many. But there may be new hope for pimple poppers everywhere. A new study suggests viruses could be used to treat acne, and effectively kill acne-causing bacteria. By utilizing a harmless virus that lives on the skin, scientists...

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell. In a paper published today online in Nature Communications, the team led by researchers at The University of Texas MD Anderson Cancer Center...

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present...

Fast-evolving microbe lost a key chunk of its genome after jumping to new host A new study of a devastating bird disease that spread from poultry to house finches in the mid-1990s reveals that the bacteria responsible for the disease evolves at an exceptionally fast rate. What's more, the fast-evolving microbe has lost a key chunk of its genome since jumping to its new host, scientists were surprised to find. The missing portion contained the genes that made up the microbe's immune system,...

Mass Spectrometry Rapidly Detects Staph Infections
2012-01-13 04:12:37

Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus. Quickly and accurately detecting infections caused by S. aureus is critical because the pathogenic bacterium causes a...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
