Bacteria resistant to common antibiotics are on the rise in communities, and outpatients are carrying them into hospital settings, according to research published in the December issue of Emerging Infectious Diseases.
Research shows rise in antibiotic-resistant bacteria
The strain of community-associated methicillin-resistant Staphylococcus aureus, dubbed CA-MRSA, can be resistant to drugs and cause infections if picked up in areas such as fitness centers, schools and other public places. CA-MRSA is on the rise in outpatient settings, increasing 33% annually from 1996 to 2006, according to researchers who studied the frequency of MRSA acquired both in hospitals and in communities through the electronic database known as the Surveillance Network, which collects information from U.S. microbiology laboratories. Inpatients also were found to have the CA-MRSA strain, as well, compounding the problem of MRSA in hospitals.
Despite the increased prevalence, CA-MRSA is more susceptible to antimicrobial drugs than its counterpart, hospital-acquired MRSA, the researchers wrote in their report. “Persons with these infections may be able to be treated with less expensive antimicrobial drugs with fewer adverse outcomes.”
Separately, the Infectious Diseases Society of America is calling on the U.S. and the European Union to support its goal of developing 10 new antibiotics in the next 10 years. The society said the World Health Organization has named antimicrobial resistance one of the three greatest threats to health.
