Pseudomonas aeruginosa targets opponents' cell walls and immunizes itself against its own weapons When competing for food and resources, bacteria employ elaborate strategies to keep rival cells at bay. Scientists have now identified a pathway that allows disease-causing bacteria to attack other bacterial cells by breaking down their cell wall. Pseudomonas aeruginosa is a type of bacteria readily found in everyday environments. It easily forms colonies in a wide variety of settings, including...

Looking in vivo at virus-bacterium associations sets stage for better understanding of such interactions in human health Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts. More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages. In part, this is due to the difficulty of culturing bacteria and viruses that have...

WAGENINGEN, The Netherlands, May 24, 2011 /PRNewswire/ -- The USDA has approved LISTEX as an antimicrobial processing aid to combat Listeria monocytogenes. Listeria is considered one of the most important food safety threats, due to its high mortality rate of over 20% and its risk to pregnant women. Today's USDA's decision will enable food processing companies to deliver safer clean label products to the marketplace, without the need for reformulation or compromise on quality. The...

Researchers at the University of Alberta have taken an important step in understanding an immune system of bacteria, a finding that could have implications for medical care and both the pharmaceutical and dairy industries. In research published in the high impact journal Nature Structural & Molecular Biology, Andrew MacMillan and co-workers in his lab have described the first step of the immune response of bacterial cells. Scientists had previously found that a bacterial virus, called a...

A team of Universit© Laval and Danisco researchers has just unlocked the secret of bacteria's immune system. The details of the discovery, which may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics, are presented in today's issue of the scientific journal Nature. The team led by Professor Sylvain Moineau of Universit© Laval's Department of Biochemistry, Microbiology, and Bioinformatics showed that this mechanism, called CRISPR/Cas,...

Viruses can wreak havoc on bacteria as well as humans and, just like us, bacteria have their own defense system in place, explained Professor John van der Oost, at the Society for General Microbiology's spring meeting on March 31. Uncovering the workings of the bacterial "immune system" could be used to keep industrial microbes at peak performance. Professor van der Oost and his team at Wageningen University in the Netherlands have spent the last three years working out the molecular details...

Call it advanced warfare on the most elemental of levels.Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival.To be more accurate, the genetic material isn't really captured as much as it is simply utilized after it's injected into the bacteria by an invading virus, says...

New York University School of Medicine researchers say they are startled to find bacteria may have the capability to stealthily transfer toxic genes. In laboratory experiments, scientists John Chen and Dr. Richard Novick, discovered the bacterium Staphylococcus aureus could co-opt viruses that infect bacteria, called bacteriophages, and use them as pipelines to transfer genetic material to another kind of bacteria -- Listeria monocytogenes. This is the first time, the researchers say, that...

Scientists have discovered a new way for bacteria to transfer toxic genes to unrelated bacterial species, a finding that raises the unsettling possibility that bacterial swapping of toxins and other disease-aiding factors may be more common than previously imagined. In a laboratory experiment, the scientists from NYU School of Medicine discovered that Staphylococcus aureus, a notorious bacterium that causes toxic shock syndrome and many other types of infections and is the scourge of...
