A resistance gene that allows bacteria to beat an important class of antibiotics has started to appear in microorganisms taken from Midwestern patients, according to researchers at Washington University School of Medicine in St. Louis.

GPs are unnecessarily giving patients antibiotics for respiratory tract (RT) infections which would clear up on their own. Doctors tend to over-emphasise symptoms such as white spots in the throat, rather than looking at factors such as old age and co-morbidity, which would affect a patient's recovery, according to an article published in the online open access journal, BMC Family Practice.

A team of tuberculosis (TB) experts at Johns Hopkins and in Brazil have evidence that substituting the antibiotic moxifloxacin in the regimen of drugs used to treat the highly contagious form of lung disease could dramatically shorten the time needed to cure the illness from six months to four.

Scientists have what could be some very bad news for disease-causing bacteria. All three major classes of antibiotics that kill infectious bacteria do so in part by ramping up the production of harmful free radicals, researchers report in the September 7, 2007, issue of Cell, a publication of Cell Press.

Biomedical researchers at Boston University’s College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called “superbugs,” bacteria that have developed resistance to common antibiotics. The researchers have discovered a previously unknown chain of events occurring in bacteria that opens to door to new avenues of research.

Probiotics, the friendly bacteria beloved of yoghurt advertisers, may be an effective substitute for growth promoting antibiotics in pigs, giving us safer pork products, according to scientists speaking today (Wednesday 5 September 2007) at the Society for General Microbiology’s 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.

Viruses found in the River Cam in Cambridge, famous as a haunt of students in their punts on long, lazy summer days, could become the next generation of antibiotics, according to scientists speaking today (Monday 3 September 2007) at the Society for General Microbiology’s 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.

University of Illinois at Chicago researchers have identified new sites on the bacterial cell's protein-making machinery where antibiotics can be delivered to treat infections.

With infections increasingly resistant to even the most modern antibiotics, researchers at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) report in the September issue of Nature Reviews Microbiology on new clues they have uncovered in immune system molecules that defend against infection.

Computer analysis of existing drugs may be key to fighting new infectious agents and antibiotic-resistant pathogens like deadly tuberculosis strains and staph ‘superbugs,’ according to researchers in Canada. The use of such “emergency discovery” technology could save time, money and lives during a sudden outbreak or a bioterrorism attack, the scientists said.

The routine use of antibiotics in swine production can have unintended consequences, with antibiotic resistance genes sometimes leaking from waste lagoons into groundwater.

Antibacterial soaps show no health benefits over plain soaps and, in fact, may render some common antibiotics less effective, says a University of Michigan public health professor.
