"New research suggests the mix of microbes in our guts can either help — or hinder — weight-loss efforts.

"We started with the premise that people have different microbial make-ups, and this could influence how well they do with dieting," explains Purna Kashyap, a gastroenterologist at the Mayo Clinic in Rochester, Minn.

As part of the study, Kashyap and his collaborators tracked the progress of people who were enrolled in a lifestyle-intervention program for weight loss. The participants were advised to follow a low-calorie diet, and they were tracked closely for about three months.

"We found that people who lost at least 5 percent of their body weight had a different gut bacteria as compared to those who did not lose 5 percent of their body weight," Kashyap explains. Their findings are published in the journal Mayo Clinic Proceedings."

"The successful dieters had an increased abundance of a bacteria called Phascolarctobacterium, whereas another bacteria, Dialister, was associated with a failure to lose the weight. And, Kashyap says it's likely that there are other types of bacteria that might influence dieting as well." 

Bottom line: the bacteria eat what else can't

"Probiotics that are currently on the market would not be effective. The idea is to develop a new product that includes the specific types of bacteria linked to successful dieting.

But it's not so simple to manipulate the mix of microbes in our guts. Identifying the organism — or organisms — that are thought to be beneficial is just the first step."

"How can I prevent it spreading?

Good personal hygiene is essential.

Always wash and dry your hands:

• after using the toilet

• after changing a baby’s nappy

• before preparing food

• after handling raw food 

• after contact with pets and other animals 

• after contact with contaminated bedding or clothing.

Keep contact with an infected person to a minimum especially while they have symptoms.

At home, an infected person should keep a hand towel that only they use.

Wash all clothes, bedding and towels from an infected person in the washing machine at the hottest cycle possible for the type of clothing to be washed.

Clean toilet seats, toilet bowls, flush handles, taps and wash hand basins regularly with hot soapy water."

"Also known as VTEC, Escherichia coli O157, is a bacterial infection that can cause severe stomach pain, bloody diarrhoea and kidney failure, according to NHS Choices.
It’s found in the poo and stomachs of cattle and other animals and is caught by eating contaminated food, including raw leafy veg and undercooked meat. Swimming in ponds or streams that are contaminated can also be an issue.
Symptoms generally occur around three to four days after first being infected, but can start anywhere between one to 14 days afterwards and can last up to two weeks.


The NHS says “a small number of people with E. coli O157 infection go on to develop a serious condition called haemolytic uraemic syndrome (HUS). This can sometimes lead to kidney failure and death, although this is rare. The risk of HUS is highest in children aged under five years.”"

"The mcr-1 gene makes bacteria resistant to colistin, an antibiotic used to treat multi-drug-resistant infections, including carbapenem-resistant Enterobacteriaceae or CRE, which US health officials have dubbed a 'nightmare' bacteria.
Colistin is the last antibiotic used to combat bacteria that are resistant to the strongest antibiotics."

"​Food Safety New Zealand says listeriosis is a rare but potentially life-threatening disease with a high death rate.
Listeria symptoms can be flu-like, including high temperature, aches, chills, vomiting and diarrhoea.
"Healthy adults are likely to experience only mild infection, causing flu-like symptoms or gastroenteritis.
"However, Listeria infection can occasionally lead to severe blood poisoning (septicaemia) or meningitis."
