Researchers at the Virginia Bioinformatics Institute at Virginia Tech and the National Animal Disease Center in Ames, Iowa, and collaborators at 454 Life Sciences of Branford, Conn., have sequenced the genome of Brucella abortus strain S19. Strain S19 is a naturally occurring strain of B. abortus that does not cause disease and was discovered by Dr. John Buck in 1923.

Laboratory tests and field studies conducted by James Madison University (JMU) researchers continue to show promise that probiotic bacteria can be used to help amphibian populations, including the endangered yellow-legged frog, fend off lethal skin diseases.

A new study by a team of researchers at the Welsh School of Pharmacy, Cardiff University, Wales, UK, has found that antimicrobial-containing wipes currently used to decontaminate surfaces in hospitals can spread pathogens after first use.

A team of Penn State scientists has discovered a new ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles.

The conventional wisdom among scientists has long been that birds acquire the intestinal bacteria that are a necessary for good health from their environment, but a new University of Georgia study finds that chickens are actually born with those bacteria.

A strain of marine bacteria produces large amounts of bright red pigments that can be used as a natural dye for wool, nylon, silk and other fabrics, scientists in California are reporting.

Many bacteria break their metabolic processes into chunks. That may be logically tidy, but it’s often metabolically inefficient. Researchers have now figured out the factors that tend to make bacteria more modular.

Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature.

IRI Separation Technologies (TSX.V:IRI) is the manufacturer of a remarkable new dietary supplement that enhances the human body’s natural immune system through direct supplementation of actual antibodies . The product will be available in the United States and Canada under the brand name “Muno Boost” and will be available as an over-the-counter dietary supplement in pharmacies and through direct marketing.

Advanced chemical analyses reveal that, with the help of smart scavenging bacteria, sulfur and iron compounds accumulated in the timbers of the Swedish warship Vasa during her 333 years on the seabed of the Stockholm harbour. Contact with oxygen, in conjunction with the high humidity of the museum environment, causes these contaminants to produce sulfuric acid, according to a new doctoral thesis in chemistry from Stockholm University.

Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation.

Too much of a good thing could be harmful to the environment. For years, scientists have known about silver’s ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles.
