Deadly Superbugs Pose Greater Threat Than Previously Estimated

Drug-resistant germs sicken about 3 million people every year in the United States and kill about 35,000, representing a much larger public health threat than previously understood, according to a long-awaited report released Wednesday by the Centers for Disease Control and Prevention. The new estimates show that, on average, someone in the United States gets an antibiotic-resistant infection every 11 seconds, and every 15 minutes, someone dies.

‘Superbug’ Infections are on the Rise, a New CDC Report Says

“We see people from everyday life, who are young and otherwise healthy, who get a MRSA [methicillin-resistant Staphylococcus aureus] infection on their skin,” says CIMAR Director Dr. Helen Boucher. “We want to have diagnostic tools and medical treatments for problems we know we’re going to have,” she said. “But we also need to prepare for the kind of resistance that we could never predict. We know from history that bacteria and mother nature are smarter than we are.”

New Antibiotics Needed "Yesterday" to Tackle Drug-Resistant Infections, Says CIMAR Director

When Roxana Sudderth’s son, Trey, a healthy high school freshman, developed a sore on his foot after playing basketball, “it just looked like a small blister.” Doctors gave him antibiotics, but the pain persisted. Sudderth took him to the hospital where they told her he had a life-threatening infection, MRSA, a bacterium resistant to antibiotics. Over 19 days, his condition deteriorated until finally doctors told Sudderth it was time to take Trey off life support.

Wellcome Trust Report Urges Better Antimicrobial Resistance Messaging

A new report suggests clinicians, public health professionals, and journalists need to rethink the way they talk about antimicrobial resistance to increase public understanding and promote action by policy makers. In this article, CIMAR Director Dr. Helen Boucher acknowledges that while it is challenging issue to explain to the public, stakeholders haven’t done a great job of communicating the immediacy and severity of antimicrobial resistance.

Is the Gene-Editing Tool, Crispr, the Next Antibiotic?

Desperate to find new medicines against pathogenic microorganisms, scientists are turning to Crispr, which has typically been considered for macroscopic tasks: altering mosquitoes so they can’t spread malaria, editing tomatoes so they are more flavorful and curing certain genetic diseases in humans. Now researchers are harnessing Crispr to turn a bacterium’s machinery against itself, or against viruses that infect human cells.

CIMAR LEAP Fellow Presents Groundbreaking Antimicrobial Stewardship Findings at IDWeek

Dr. Gabriela Andujar Vazquez presented groundbreaking findings from her antimicrobial stewardship pilot study at IDWeek in Washington, D.C. earlier this month.

Doctors Are Running Out of Effective Drugs Because of Poor Financial Incentives to Develop Them

Medical researchers have known for decades that the pipeline for new drugs to stave off bacterial infections would one day run dry. That day is now at hand. “The crisis has already arrived. We are in an era now when doctors like me have no effective antibiotics for some of their patients,” says CIMAR Director Dr. Helen Boucher.

Antibiotics Aren’t Profitable Enough for Big Pharma to Make More

Public health experts are calling for new incentives to reward companies for bringing drugs that are effective against resistant strains to market. Achaogen Inc. spent 15 years racing to develop antibiotics against resistant superbugs such as carbapenem-resistant Enterobacteriaceae, or CRE, a strain that can kill up to half the people it attacks. But as a business, it’s a failure. The drug,  Zemdri, lacked sales in its first six months on the market == less than $1 million. Achaogen filed for bankruptcy in April.

Medicare Payment Rules Hinder the Fight Against Superbugs

Late last year, a retirement community in Vermont was quarantined after an outbreak of antibiotic-resistant bacteria swept through the facility, sickening 70 seniors. In pediatric oncology wards, children beating cancer are increasingly felled by drug-resistant bacteria and fungal infections. Every week, we hear more stories of infections that have become untreatable due to resistance. Such alarms, once rare, are becoming more commonplace. The time to fix the problem is now, before it’s too late.
