Bacteria

The World Health Organization has released a list of 12 antibiotic-resistant superbugs that pose the greatest danger to human health.

The purpose of the list of “priority pathogens,” according to WHO, is to promote continued research and development of drugs that can be used to treat patients with these resistant infections.

The agency has divided the list according to the urgent need for new antibiotics. The bacteria considered the most critical pose a particular threat to hospitalized patients who may require blood catheters or ventilators. These bacteria, which can cause severe and deadly infections, such as bloodstream infections and pneumonia, are also resistant to drugs designed as a last line of defense for patients.

“This list is a new tool to ensure R&D responds to urgent public health needs,” Marie-Paule Kieny, Ph.D., assistant director-general for health systems and innovation at the WHO, said in an announcement. “Antibiotic resistance is growing, and we are fast running out of treatment options. If we leave it to market forces alone, the new antibiotics we most urgently need are not going to be developed in time.”

Three bacteria resistant to carbapenem, an antibiotic that often treats bacteria that are resistant to other drugs, are listed as critical. Six bacteria are ranked as high-priority and the final three are listed as medium-priority. Bacteria listed as high- or medium-priority are increasingly becoming resistant to different antibiotics and are producing hard-to-treat strains of common conditions, such as gonorrhea and salmonella.

One of the three critical bacteria, carbapenem-resistant Enterobacteriaceae, or CRE, resulted in the death of a Nevada woman last year, and estimates suggest the infection may be more widespread than previously thought.

Global health experts have increasingly warned that superbugs are poised to be a significant threat to patient health. In the next decades, drug-resistant infections could kill more people than cancer. Providers can do their part by focusing on antibiotic stewardship. National healthcare organizations, including the Centers for Medicare & Medicaid Services, have offered guidelines.

Here is the complete list compiled by WHO:

Superbug resistant to two last-resort antibiotics found in US for first time

Superbug resistant to two last-resort antibiotics found in US for first time

A strain of E. coli resistant to two last-resort antibiotics has for the first time been reported in the United States.

The strain was found in the urine of a man treated at a New Jersey hospital two years ago. It was tested in 2016 as part of a larger analysis of bacteria from the hospital.

For hard-to-treat bacteria infections, the antibiotics colistin and carbapenem are considered the big guns — a last line of defense when nothing else is working. In recent months mcr-1, a gene which confers resistance to colistin, has been found in E. coli from over 30 countries, including bacteria isolated from pigs and people in China and a patient in New York City.

Similarly the gene blaNDM-5 renders the antibiotic carbapenem useless against its bacterial carrier. In 2012, the Centers for Disease Control and Prevention found carbapenem-resistant bacteria in about 4 percent of US hospitals.

Researchers and health officials have feared the joining of these two genes in a single bacterial strain, as it could set the stage for the rise of superbugs that can’t be treated with our current arsenal of drugs. The combination has been detected before in other countries, including Germany, Venezuela, and China, but until now, it has never been seen within the United States.
