In the E. coli outbreak in Germany in May 2011, treatment with azithromycin was associated with a lower frequency of long-term carriage of the bacteria and shorter duration of shedding of the bacteria in stool specimens, according to a new study.

Chemists have created a compound that makes existing antibiotics 16 times more effective against recently discovered antibiotic-resistant "superbugs."

North Carolina State University chemists have created a compound that makes existing antibiotics 16 times more effective against recently discovered antibiotic-resistant "superbugs."

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galápagos islands are more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report in a new study.Feces collected at several different sites from ...

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galapagos islands were more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report. Many of the reptiles harbor E. coli bacteria that are ...

Microbiologists have identified a new bacterial growth process -- one that occurs at a single end or pole of the cell instead of uniform, dispersed growth along the long axis of the cell -- that could have implications in the development of new antibacterial strategies.

Drugs used to overcome cancer may also combat antibiotic resistance: McMaster researchers – The pharmaceutical sector has made a big investment in targeting kinases proteins, so there are a lot of compounds and drugs out there that, although they were designed to overcome cancer, they can in fact be looked ...

Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That's the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor.

Some of the nastiest smelling creatures on Earth have skin that produces the greatest known variety of antibacterial substances that hold promise for becoming new weapons in the battle against antibiotic-resistant infections, scientists are reporting. Their research is on amphibians so smelly (like rotten fish, for instance) that scientists term ...

Researchers say they've found evidence of a massive network of recent gene exchange connecting bacteria from around the world: 10,000 unique genes flowing via horizontal gene transfer among 2,235 bacterial genomes. Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear ...

A vampire-like bacteria that leeches onto specific other bacteria -- including certain human pathogens -- has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates.

Antibiotic-resistant enterococci are a serious problem for patients in the hospital, but little is known about how these bacteria are able to escape antibiotics. New discoveries about the ways in which enterococci turn their resistance to cephalosporin antibiotics on and off are described in a new study.
