Scientists trick bacteria to incorporate foreign small molecules into cell wall

Researchers at Yale University have artificially created the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall.

The finding represents the first time scientists have engineered the cell wall of a pa... Read More

Scientists Decode Lyme Disease Genome

Are better treatments for Lyme disease on the horizon? Things are looking up, scientists say, thanks to new research into the genetic make-up of the bacteria that cause the tick-borne illness.

The research yielded complete genetic blueprints of the 13 different strains of bacteria that cause ... Read More

Do gut microbes play cancer role?

Microbes matter, perhaps more than anyone realizes in biological development, and scientists now believe they could be a target for reducing cancer risks.

In a study of very basic biology of zebrafish, scientists focused on the developing intestine during its early formation in the sterile en... Read More

Deadly bacteria's foothold spurs study

News that a hard-to-treat, potentially lethal germ had landed on US shores from India spawned sensational headlines last month about the emergence of a “superbug’’ capable of outwitting the best antibiotics available. So far, just three cases of this NDM-1 bacterium have been identified in the U... Read More

Bacteria can exacerbate asthma symptoms even if they aren't infected with a virus

Doctors have long known that viral infections can bring about asthma attacks and the shortness of breath, coughing, and wheezing associated with them. But while viral infections cannot be treated, scientists at the Danish Paediatric Asthma Centre at the University of Copenhagen and Copenhagen Un... Read More

Utilizing bacteria to biomonitor the state of oil fields

Geert van der Kraan, Department of Biotechnology, Delft University of technology, believes the ups and downs of the bacteria in an oil field provide a useful source of information for keeping tabs on the state of the oil field itself. In theory, this process known as 'biomonitoring' can increase... Read More

Bacteria can walk on 'legs'

Alan Boyle writes: Bacteria have legs? That suggestion seemed surprising to Gerard Wong, a bioengineering professor at the University of California at Los Angeles, when his students told him they were seeing some strange behavior in movies of the microbes.

"They said, 'You know, we noticed th... Read More

Life-Saving in the Bacterial World: How Campylobacter Rely on Pseudomonas to Infect Humans

The bacterium Campylobacter jejuni is a major cause of food poisoning in humans. It is normally transmitted from contaminated chicken meat, as it is frequently found in the intestines of chickens, where it apparently does not result in any symptoms. Campylobacter jejuni is well adapted to life ... Read More

Bacteria Keep Tabs on State of Oil Field

The ups and downs of the bacteria in an oil field provide a useful source of information for keeping tabs on the state of the oil field itself. In theory, this process known as 'biomonitoring' can increase the yield from an oil field. This is the conclusion reached by Geert van der Kraan, who ob... Read More
