We are likely to think of fungi, if we think of them at all, as minor nuisances: mold on cheese, mildew on shoes shoved to the back of the closet, mushrooms springing up in the garden after hard rains. We notice them, and then we scrape them off or dust them away, never perceiving that we are engaging with the fragile fringes of a web that knits the planet together.
Disease experts are now worrying that the next pandemic could be caused by fungi rather than a virus. National Geographic has recently reported a terrifying possibility, scientists say, given how little we know about the organisms.
Many fungi have been known to grow resistant to treatments, heightening the stakes. What scientists worry about all the time in the fungal world, is fungi’s potential to cause human disease. Fungi can evolve at extremely fast rates, turning into infections that are increasingly difficult to treat with antifungals. They can also force the immune system to turn against itself, a life-threatening condition known as sepsis. In a particularly alarming detail, the National Geographic magazine even reported that fungi can form balls inside the body that can displace entire organs.
According to the report, mortality rates shoot up by 25 percent in the case of antifungal-resistant pathogens. The use of fungicides in the agricultural industry, for instance, allows resistant fungi to grow stronger and develop potentially dangerous immunities.
While they mutate more slowly than bacteria or viruses, generally speaking, fungi can adapt and reproduce in a great range of environments.
And that's bad news if they were ever to start spreading rapidly in humans.
According to the report, perhaps resistance to one fungicide develops in one individual and resistance to another fungicide develops in another. They can bring those resistances together through sexual reproduction and then it can explode.
Climate change could even be adding to the problem, making temperatures friendly to dangerous fungi.
In short, fungi should almost certainly be on the list of potential threats when it comes to mass outbreaks of human pathogens.
That's why experts are calling for additional funding to study fungal pathogens. Scientists are already working on developing fungal vaccines, some of which are already being tested in clinical trials.
Fungi are some of the most ubiquitous organisms on the planet — and in fact, many have proven to be incredibly useful to us. But under the right conditions, they could turn against us in an alarmingly short period of time.
So maybe it's best to get ahead of the problem now, before it's too late.
