Superbug is evolving to thrive in guts of people with sugary diets, scientists warn

The sugar-rich Western diet is fueling a superbug which has evolved to thrive in hospitals, scientists have warned.

The gut-infecting bacterium Clostridium difficile (C.diff) is evolving into two separate species, with one group increasingly adapting to live in the guts of people with poor diets, while growing ever better at avoiding the harsh disinfectants used to clean wards.

More than 13,000 NHS patients each year are infected with C.diff, which can cause debilitating diarrhoea and leave sick people dangerously dehydrated.

Bacteria are also becoming increasingly resistant to antibiotics, and if not treated quickly enough an infection can be fatal. Nearly 2,000 people die from the bacterium each year in Britain.

Researchers at the Wellcome Sanger Institute and London School of Hygiene & Tropical Medicine looked at the genetic differences of 906 strains of C-diff taken from humans and animals and the environment across 33 countries.

They found that a dangerous new species is rapidly emerging which can evade common hospital disinfectants and spread easily. And poor diets are making the problem worse.

Dr Trevor Lawley, the senior author from the Wellcome Sanger Institute, said: “Our study provides genome and laboratory based evidence that human lifestyles can drive bacteria to form new species so they can spread more effectively.

“We show that strains of C. diff bacteria have continued to evolve in response to modern diets and healthcare systems and reveal that focusing on diet and looking for new disinfectants could help in the fight against this bacteria.”

Researchers found that the new emerging species, named C. difficile clade A, made up approximately 70 per cent of the samples from hospital patients.

It had changes in genes that allow it to feed on simple sugars, and when tested in animals, it was able to colonise mice guts more thoroughly when their diet was high in sugar.

It had also evolved differences in the genes involved in forming spores, giving much greater resistance to common hospital disinfectants. These changes allow it to spread more easily in healthcare environments.

Dr Nitin Kumar, joint first author from the Wellcome Sanger Institute, said: “Our large-scale genetic analysis allowed us to discover that C. diff is currently forming a new species with one group specialised to spread in hospital environments.

“This is the first time anyone has studied genomes in this way to identify it. This particular bacteria was primed to take advantage of modern healthcare practices and human diets, before hospitals even existed.”

Encouraging people to change their diet, or making sure hospital food is as healthy and sugar-free as possible could help to stave off infections, the study suggests.

Prof Brendan Wren, an author from the London School of Hygiene & Tropical Medicine, said: “Ultimately, this could help understand how other dangerous pathogens evolve by adapting to changes in human lifestyles and healthcare regimes which could then inform healthcare policies.”

The research was published in the journal Nature Genetics.

Good question I don't know the answer to, but I'm hoping at least to defend against it indirectly by low carb keeping me well and out of the medical settings it's in.

Lol, I steer clear of hospitals too.

Used to be the cut thru of the local hospital was thru the emergency rooom. Guess they smartened up and moved the emergency area to other side if building, where the main entrance WAS.

If it feeds on sugar in the gut, I can only hope my bad bugs are wandering around like a cartoon hobo, picking through the trash.
