New research from The Novo Nordisk Foundation Centre for Biosustainability in Denmark has for the first time provided evidence to back up what biologists have long suspected – the resistance genes come from the same source as the antibiotics themselves.

Scientists have discovered a new antibiotic effective against drug-resistant bacteria: pseudouridimycin. The new antibiotic is produced by a microbe found in a soil sample collected in Italy and was discovered by screening microbes from soil samples. The new antibiotic kills a broad spectrum of drug-sensitive and drug-resistant bacteria in a test tube and cures bacterial infections in mice.

Chemical changes give drug three killing methods plus a way to daze evolution.

Lactobacillus parafarraginis metabolites hindered the growth of multiple, distantly related bacterial pathogens.

Doxycycline, an antibiotic used for over half a century against bacterial infections, can be prescribed at lower doses for the treatment of Parkinson's disease, say researchers.

The number of cases of an emerging and often multidrug-resistant fungus in the United States has grown from seven to 122 over the past nine months, according to a field report in the Morbidity and Mortality Weekly Report issued Thursday by the US Centers for Disease Control and Prevention.

Researchers have found a way to penetrate the cell wall of gram-negative bacteria, overcoming a major barrier to the development of new broad-spectrum antibiotics.

It is well-known that prolonged exposure to high doses of antibiotics can increase tolerance and sometimes strengthen the very bacteria that antibiotics are trying to kill. New research, however, suggests that an extract from maple syrup may boost the efficacy of antibiotics and reduce their side effects.
