A US woman has shared an update on her recovery after losing all four of her limbs after doing a ‘normal’ thing while walking into her house.

When Marie Trainer returned home from a tropical holiday in the spring of 2019, she had no idea that her life would transform forever.

Marie received a warm welcome home from her dog, being greeted by kisses from the beloved pooch who was no doubt delighted to see her again.

The greeting for the Ohio resident was so normal that she didn’t even think twice about the small cut on her hand at the time.

However, a couple of days later, her life would change forever.

Over the following four days, Marie began to feel progressively more unwell, with her husband of 37 years, Matt Trainer, later taking her to get checked out at a local hospital.

“I wasn’t feeling well and just got sicker and sicker,” she explained, after seeking medical attention Marie slipped into a coma as doctors were able to understand what exactly had happened to her.

Subsequent examinations at her local hospital and the Cleveland Clinic would reveal that Marie had contracted a rare infection from bacteria called capnocytophaga canimorsus.

What is capnocytophaga canimorsus?

According to the Centre for Disease Control and Prevention, capnocytophaga bacteria commonly found in the saliva of dogs and cats.

If the bacteria enters the human body it can cause a rare – but potentially fatal – infection.
