Transmitter of super-bug E. coli is poor hand hygiene

One of the best ways to reduce E-resistant antibiotics. A UK study suggests that coli infections should make sure everybody washes their hands after using the toilet.

E coli outbreaks — a potentially lethal disease — are commonly attributed to undercooked meat or raw vegetables, but when researchers conducted a genetic sequencing of thousands of samples, they discovered that the majority of E coli infections in the UK were caused by strains often found in the human gut and sewage, but not much seen in the food supply.

This suggests that the infection is mainly caused by human faecal particles conveyed from person to person, Lancet Infectious Diseases writes the study team.

David M. Livermore, a medical microbiologist at East Anglia University, as well as his co-workers call E coli a “Jekyll and Hyde organism.” E coli lives mainly harmless in people and animals, but a couple of nasty strains can eventually cause poisoning as well as bloodstream infections.

Researchers have understood that super-bug E coli strains are circulating like chickens in humans and food animals. But it was unknown if they picked up the bloodstream infections from the food chain or transmitted between people.

The researchers conducted genome sequencing on samples from humans, animals and sewage collected in 2013 and 2014 in five areas: London, East Anglia, Northwest England, Scotland as well as Wales.

Researchers compared samples from human bloodstream infections, human waste, animal slurry, as well as foods such as beef, pork, chicken, fruit and vegetables.

DNA sequencing has shown that E is resistant to antibiotics. In sewage as well as retail chicken meat, coli was sometimes seen, but seldom on other meats and never on plant-based foods.

Furthermore, specimens of a specific strain of E resistant to antibiotics. Coli called ST131 gathered from human blood, faeces and sewage all matched one another-but chicken, cattle and animal slurry strains were not matched.

Livermore and Barlam both noted that careful hygiene, like most severe E, is particularly important for the elderly in homes. In these settings, coli urinary tract infections and bacteremia occur.
