A new understanding of an enzyme important for the transfer of genetic information in bacteria may help scientists improve current antibiotics and also create antibiotics that are less vulnerable to resistance.
In the last 60 years, gonorrhea has become resistant to sulfonamides, penicillins, tetracyclines, and ciprofloxacin. Results of a 16-year monitoring program find it is becoming resistant to yet another antibiotic class, fluoroquinolones.
The structure of a novel protein in the bacterium that is the most persistent pathogen in cystic fibrosis (CF) patients has been solved.
The use of prophylactic antibiotics, which involves daily administration of antibiotics to children after an initial urinary tract infection, is not associated with reduced risk of recurrent urinary tract infections, but is associated with an increased risk of resistant infections, according to a study in the July 11 issue of JAMA.
Putting bacteria on birth control could stop the spread of drug-resistant microbes, and researchers at the University of North Carolina at Chapel Hill have found a way to do just that.
Laboratory tests conducted at National Jewish Medical and Research Center indicate that patient Andrew Speaker?s tuberculosis is susceptible to some of the medications previously thought ineffective against his disease.
The U.S. Food and Drug Administration continues to warn the American public about the dangers of buying medications over the Internet.
It infiltrates hospitals as microscopic spores. Its defenses are so strong it can resist most antibiotics. And it kills three times as many people every year as MRSA. But scientists at the University of Nottingham are amassing an arsenal of weapons in preparation for counter offensive against the most deadly of hospital superbugs.
People who have high cholesterol levels may be much more susceptible to a particular disease transmitted by the bites of ticks, a new study in mice suggests.
Drinks containing probiotic bacteria can help reduce diarrhoea among older people, which may reduce length of stay in hospital and save the NHS money, say Imperial College researchers at Hammersmith Hospital in a study published on bmj.com.
