Until recently, scientists found it a mystery how C. auris appeared in more than 30 countries across the globe a decade after it was first discovered in 2009. It emerged at the same time in three continents – in India , Venezuela and South Africa – between 2012 and 2015, each of which is genetically distinctive.
The new study, published in the MBI magazine, says that this serious threat to public health may be the first example of a new mold disease due to the climate crisis.
"The argument we make based on comparison with other close relative families is that, because the climate has become warmer, some of these organisms, including Candida auris, have adapted to a higher temperature and, if they adapt, they break through the protection of human temperatures, "said co-author Dr. Arturo Casadevall, president of molecular microbiology and immunology at Johns Hopkins Bloomberg School of Public Health.
"Global warming can lead to new molds that you & # 39; t even know."
Experts have warned that the climate crisis could be made in & # 39; the health of a human being.
For the study, researchers looked at the thermal sensitivity of C. auris and found that it could adapt to higher temperatures and then grow much of their fungi 's relatives.
This study theory suggests that C. auris was an environmental mold, which was initially found in wetland and perhaps had an intermediate host like a sea bird and then passed on to humans.
Fungal infections are relatively rare in humans, because the molds cannot grow in the body's temperature range and because of the natural mechanisms of the body of defense.
Earlier studies have shown that from millions of species to a few, but a few hundred people have been affected.
Heavy cases of this superbug can in some patients cause a blood infection according to the US Centers for Disease Control and Prevention and it poses a "serious global health threat."
The mold can draw on medical equipment for healthcare and long-term facilities and can transfer one person to another, have previously shown evidence.
Since then, other factors may be late in the emergence of this superbug, the authors suggest that more research is needed.
A study published earlier this year suggested that a change in climate conditions could change the environmental spreading of molds and their ability to infect others may affect, but "given a lack of knowledge about its natural habitat, it is currently impossible to determine climatic changes play a role in their recent emergence as a human pathogen. "
Other studies have claimed the widespread use of antifungal drugs, but the latest study suggests that the theory does not easily explain why it was a human pathogen on three continents.
But in spite of better monitoring systems, it is necessary to look for fungal infections such as C. auris, authors said. In addition to reporting illnesses in medical literature, scientists will not know that the fungi spread.
