Recent research picks up outside India Concerns over the transmission risk of a harmful and hard-To-Kill fungal infections. in study . drug resistant strains of candida auris On apples that were treated with fungicide. The findings suggest that apples and other fruits with these chemicals may inadvertently promote its emergence and spread. germs, which cause deadly outbreaks in hospitals.

c. auriso is an emerging pathogen and yeast (microscopic fungus) that was first discovered in 2009. Although most people exposed to it do not get sick, it can cause a serious infection in some people, especially those who are already sick or immunocompromised. This has made the fungus a serious threat to hospitals and other health care environment. It is also often resistant to some of the antifungals used against it. Whereas c. auriso outbreaks are raredoctors have already encountered cases that were resistant to all available drugsincluding in the US

Fungi are believed to have existed in nature for quite some time, despite their recent emergence in humans. Last year, researchers in Canada and India were to document it in forest, living in hot island areas away from India. The same team behind this latest research, published MBO in March

In 2020 more 2021, tOho The surfaces of 84 fruits grown or sold in India were collected and sampled, most of which looked for disease-causing yeast, such as apples. c. auriso, Feather IEight of these apples (13%), they found a variety of drug-resistant strains of the fungus. None of the apples freshly picked from an orchard had a mark c. aurisoAlthough; The apples stored and sold at stores often contained other related species. candida on them too.

These findings indicate, studalreadyThe process of treating apples and other fruits with fungicides is often used to prevent them from spoiling, says Youths.—helping to fuel the growth of these superbugs. a similar incident Can be seen in antibiotic-treated animals or in people who have been given antibiotics that do not clear up their entire infection, which then allows drug-resistant strains of bacteria to emerge.

“Our findings suggest that c. auriso exposure to agricultural fungicides in natural ecosystems and that stored fruit may be an important site for selection for azole resistance c. auriso and other human fungal pathogens, “scientists” wrote.

While the team’s research has focused on finding c. auriso In India, they caution that this is not just a local problem. In fact, in recent years, outbreaks have been seen in previously unspecified areas of the world, including Brazil and in New Area of America

More research is needed to understand the exact risk that fruits and vegetables play a role in the spread. c. auriso And Other routes of its exposure. But one thing is certain: It is growing fast It’s hard to avoid being exposed to this and other superbugs.

“When we look at human pathogens, we see what is immediate to us,” says study author Jianping Xu, a microbiologist at McMaster University in Canada., said Indian newspapers The Tribune. “But we have to look at it more broadly. Everything is connected, the whole system. Fruit is just one example.”
