Scientists from California and Hong Kong genetically engineered bacterial cells so that they spontaneously grow in concentric rings. The number of rings can be controlled by altering expression of a single gene. They say the findings could shed light on the complex patterning that takes place du... Read More

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial “ge... Read More

The launch of new antibiotics in the 1980s led many in the scientific field to believe that fight against bacteria had been won. Since then, at least one group of bacteria known as Gram-negatives (which includes pathogens responsible for hospital-acquired pneumonia and bloodstream infections as ... Read More

Needle-based vaccine injections require highly trained health workers and an optimally performing system for effective mass vaccination campaigns. The universal fear of needle sticks is an indicator of the need of convenient and viable alternative modes of delivery. New technologies are making n... Read More

Clostridium difficile infection is an important cause of intestinal disease, primarily affecting hospitalized patients exposed to antibiotics. Infection has been associated with prolonged hospital stays and excess healthcare expenditures.Recent changes in epidemiology of this disease show a rise... Read More

ICAAC is traditionally a venue for presenting data on new drugs and new drug combinations. Program Committee member Karen Bush, David Shlaes, MD, PhD, Anti-Infectives Consulting, Stonington, CT, and J. Kevin Judice, Ph.D., CEO, Achaogen, present an overview of new drugs and clinical trial data b... Read More

Extended spectrum beta-lactamases (ESBL's) are enzymes that enable bacteria to resist multiple antibiotics. In the past few years ESBL-producing enteric bacteria (such as E. coli) have become an increasingly common cause of community acquired infections worldwide. The source of these organisms i...

For germaphobes, seeing the movie “Contagion” will probably induce chronic hand-washing and self-imposed solitary confinement. The Matt Damon-led thriller is about a disease outbreak that pretty much consumes the entire world. To promote the film, Warner Bros. Canada embraced the film’s the... Read More

A team led by University of Maryland School of Medicine Institute for Genome Sciences researchers has unraveled the genomic code of the E. coli bacteria that caused the ongoing deadly outbreak in Germany that began in May 2011. To date, 53 people have died in the outbreak that has sickened thous... Read More
