Stealth technology maintains fitness after sex
Pathogens can become superbugs without their even knowing it, research published today in Science shows. 'Stealth' plasmids-circular 'DNA parasites' of bacteria that can carry antibiotic-resistance genes-produce a protein that increases the chances of survival and spread of the antibiotic-resistant strain. view more (2007-01-12)
Antibiotic ear drops favored over popular oral antibiotics for ear infections
A multicenter study on treating common ear infections in children with ear tubes adds to a growing body of evidence that favors antibiotic ear drops over antibiotics swallowed in pill or liquid form in such cases, a UT Southwestern Medical Center researcher reports. view more (2006-12-13)
Fears about complications shouldn't drive antibiotic prescribing
Antibiotics are not justified to reduce the risk of complications after upper respiratory tract infection, sore throat, or ear infection, finds a study published on bmj.com today. view more (2007-10-19)
SULPHONAMIDE RESISTANCE REMAINS HIGH DESPITE PRESCRIBING RESTRICTION (pp 1307, 1325)
A substantial decrease in prescribing of sulphonamides in the UK over the past decade has failed to reduce resistance to this class of antibiotic drugs, conclude authors of a study in this week's issue of THE LANCET. There is a clear link between heavy antimicrobial use and the emergence of resistant bacteria. Whether a reduction in antimicrobial... view more... (2001-04-25)
Customized treatments for sepsis lower treatment time and reduce length of ICU stays
Using a blood test and a decision algorithm, rather than standard hospital protocols, to determine the appropriate length of antibiotic therapy in patients with severe sepsis or septic shock can reduce duration of treatments, shorten ICU stays, and lower hospital costs- all without adverse effects on patients, according to new research. view more (2008-02-29)
Evolution follows few of the possible paths to antibiotic resistance
Darwinian evolution follows very few of the available mutational pathways to attain fitter proteins, researchers at Harvard University have found in a study of a gene whose mutant form increases bacterial resistance to a widely prescribed antibiotic by a factor of roughly 100,000. view more (2006-04-12)
Nanotechnology boosts war on superbugs
This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at UCL are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as MRSA. view more (2008-10-13)
Antibiotic treatment targets difficult asthma
Hunter researchers have shown that a commonly available antibiotic can improve the quality of life of patients with difficult asthma, and may also generate significant health care savings. view more (2007-12-18)
Antibiotics appear to be overprescribed for sinus infections
Antibiotics are prescribed for approximately 82 percent of acute sinus infections and nearly 70 percent of chronic sinus infections, despite the fact that viruses are by far the most frequent cause of this condition, according to a report in the March issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals. view more (2007-03-20)
First placebo-controlled study of cognitive impairment due to chronic Lyme disease
Findings from the first placebo-controlled study of chronic cognitive impairment after treated Lyme disease (also known as chronic Lyme encephalopathy) demonstrate that patients report moderate cognitive impairment, physical dysfunction comparable to patients with congestive heart failure, and fatigue comparable to patients with multiple sclerosis. view more (2007-10-11)
Studies identify food sources of disease and drug resistance
As the recent U.S. outbreak of E. coli infections caused by contaminated spinach demonstrates, the safety of the food we eat cannot be taken for granted. view more (2006-10-04)
Milk may help bacteria survive against low levels of antibiotics
Milk may help prevent potentially dangerous bacteria like Staphylococcus from being killed by antibiotics used to treat animals, scientists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin. view more (2008-09-08)
Wait-and-see approach for treating ear infections substantially reduces use of antibiotics
For children with acute ear infections seen in an emergency department, giving parents the option of delaying use of antibiotics resulted in significantly lower use of antibiotics compared to parents who received a standard prescription, with little difference in the outcomes for the children. view more (2006-09-13)
Computers help chemists fight emerging infections
Computer analysis of existing drugs may be key to fighting new infectious agents and antibiotic-resistant pathogens like deadly tuberculosis strains and staph 'superbugs.' view more (2007-08-20)
Antibiotic resistant bacteria frequently transmitted between intensive care patients
Bacteria with resistance to multiple antibiotics will become more common in intensive care units unless hospitals improve their hygiene standards. Research published in Critical Care this week shows that there is an "unexpectedly high" level of transmission of bacteria between intensive care patients. view more (2003-12-18)

New Weapon for Fighting Antibiotic Drug Resistance
The most important antibiotics in general use today are the b-lactam family of products, but the medical community faces a serious problem with these antibiotics: the increasing development of drug resistance. The resistance is caused by hydrolysis of the b-lactam by a bacterial lactamase enzyme, but fortunately it can often be overcome by the use... view more... (2003-08-11)
Antibiotic treatment for children with UTI not associated with reduced risk of recurrence
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. view more (2007-07-11)
Study shows that targeted antibiotics lead to prolonged improvement in IBS symptoms
Researchers at Cedars-Sinai Medical Center have found that a nonabsorbable antibiotic - one that stays in the gut - can be an effective long-term treatment for irritable bowel syndrome (IBS), a disease affecting more than 20 percent of Americans. view more (2006-10-17)
UIC scientists discover how some bacteria survive antibiotics
Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings, published in the April 24 issue of the journal Molecular Cell, could lead to more effective antibiotics to treat a variety of infections. view more (2008-05-01)
