Who Is On The WHO’s New Most Dangerous Superbugs List

Call it the anti-Oscars, the most-not wanted, the rogues gallery, the Legion of Doom, or (maybe most appropriately) the Brotherhood of Evil Mutants of bacteria. The World Health Organization (WHO) just published its first ever list of the world’s worst antibiotic-resistant bacteria. The purpose of assembling this awful line-up? To help guide governments, scientists, and pharmaceutical companies to find the right superheroes to counter what has become serious, serious, deadly threats. The lack of antibiotics to take on these thugs is scary with a capital “Y”, as in why isn’t there more urgency and dedicated resources to develop new antibiotics, reduce antibiotics use, and bolster infection control programs? Why are many people wasting time and resources making up enemies (e.g., conspiracy theories about vaccines) when there are real potentially deadly enemies on this list?

Will this list be the spark that gets more people and organizations moving? The WHO released this list prior to a meeting of health experts from the G20 in Berlin, Germany this week. Who? Yes. Oh, what do I mean by G20? Well, these are the 20 major economies around the world: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom and United States and the European Union (EU). The goal of the list is to motivate G20 governments to fund more antibiotic and infection control research and development. Wealthier countries created this global crisis, excessively using antibiotics, which resulted in the nasties that we have today. But now antibiotic-resistant bacteria has spread throughout the world to low and middle income countries as well. Yes, movies like Batman v Superman: Dawn of Justice have not been our only bad export.

The WHO divided the rogues list into three categories of increasing concern and position on the priority list: “medium”, “high”, and “critical”, which is like “uh oh”, “oh no”, and “oh #@$%^”.  The Priority 3 or Medium priority group consist of three types of bacteria that aren’t spreading as epidemics right now but remain big problems:

  • Streptococcus pneumoniae, penicillin-non-susceptible: The Mystique of the list, coming in many different forms (serotypes) and potentially causing pneumonia, meningitis, or other infections. Vaccines do exist for many of the strains, but getting people vaccinated is another story…
  • Haemophilus influenzae, ampicillin-resistant: This is the Joker of bacteria. It remains dangerous, causing blood infections, meningitis, pneumonia, and epiglottis. Here’s the joke. Since the early 1990s, a vaccine has been available for the type b of the strain (not all strains)…but not everyone gets this vaccine due to those opposing vaccines and the cost of the vaccine. Not getting vaccinated means more possible cases, which leads to more antibiotic use, which may lead to more antibiotic-resistance. Great.
  • Shigella spp., fluoroquinolone-resistant: The result of this bacteria is like the propaganda machine for any evil dictator, lots of diarrhea. As described in Sarah Bartsch’s and my article in Human Vaccines & Immunotherapeutics, Shigella is a major cuase of dysentery aorund the world and a common cause of traveler’s diarrhea.

The Priority 2 or High priority group has six familiar villains that continue to wreak havoc:

  • Enterococcus faecium, vancomycin-resistant: VRE is like the evil character Parasite that causes problem by touch, spread by touching contaminated patients or objects. VRE infections most commonly affect the intestines, the urinary tract, and wounds.
  • Staphylococcus aureus, methicillin-resistant, vancomycin-intermediate and resistant: The Lex Luthor of bacteria. A well-known arch-enemy to many, otherwise known as MRSA, that’s been around for a while but remains very dangerous, very versatile, and very unpredictable. MRSA can cause infections ranging from difficult to treat infections to life threatening ones all around the body such as the skin, bones, blood, and lung.
  • Helicobacter pylori, clarithromycin-resistant: This bacteria can literally give you ulcers and potentially stomach cancer, living in your stomach.
  • Campylobacter spp., fluoroquinolone-resistant: Campy may describe the original Batman television series but there’s nothing fun about “the most common bacterial cause of human gastroenteritis in the world,” according to the WHO.
  • Salmonellae, fluoroquinolone-resistant: You’ve probably heard of this common cause of food-poisoning and typhoid fever (depending on the strain).
  • Neisseria gonorrhoeae, cephalosporin-resistant, fluoroquinolone-resistant: You may be familiar with gonorrhea. Hopefully not too familiar. Dr. Jonathan Mermin from the Centers for Disease Control and Prevention (CDC) told CBS News that “Our last line of defense against gonorrhea is weakening. If resistance continues to increase and spread, current treatment will ultimately fail and 800,000 Americans a year will be at risk for untreatable gonorrhea.”

The Priority 1 or Critical priority group has three of the biggest, baddest uglies that could take over and deserve the greatest attention:

  •  Acinetobacter baumannii, carbapenem-resistant: The evil Aquaman of the bunch, preferring to inhabit liquids, such as solutions used to wash, irrigate, and hydrate patients and body parts that have a lot of fluids such as the respiratory tract, urinary tract, and spinal fluid. It tends to live in intensive care units (ICU) because patients there have intravenous lines, breathing machines, catheters, and drains.
  • Pseudomonas aeruginosa, carbapenem-resistant: The Thanos or Darkseid of bacteria. It is the most commonly found bacteria in patients that have been in the hopsital more than a week and cause many complicated and life-threatening infections such as pneumonia, endocarditis, and osteomyelitis.
  • Enterobacteriaceae, carbapenem-resistant, ESBL-producing: This is the big bad one, otherwise known as CRE or the Phantom Menace bacteria. I’ve described this “nightmare” bacteria previously for FORBES and our simulation modeling studies have shown how it is spreading rapidly. Don’t get CRE.

A list alone won’t make a difference. Real change and action must follow. Unfortunately industry and many of the G20 governments such as the U.S. government have not risen to the challenge yet. Sure there are individual Supermen, Supergirls, Iron Men, and Wonder Women trying to fight the growing menace of antimicrobial resistance. But what is needed now is much more concerted and greater governmental and industry efforts..basically more Justice Leagues, Avengers, or X-Men…to tackle this very threatening line-up of super-villain superbugs.
