Fecal transplants are saving lives and their potential is flush with possibility. But there’s a desperate need for donors.

It’s quite the conversation starter. At parties or gatherings, when someone asks John Chmiel what he does, he gets a kick out of telling them “I sell poop for money.”

It’s true. He does. His own poop.

John is a poop donor.

When you are a regular poop donor like John Chmiel, you learn the tricks of the trade when it comes to collection. There are various options to make it easy to provide a sample for fecal transplant research and patient care at St. Joseph’s Health Care London.


Instead of slowly backing away, people are intrigued, says John. They want to know why and how. They quickly discover it has nothing to do with the money and everything to do with saving lives.

At St. Joseph’s Health Care London, fecal transplants are now routine treatment for debilitating and life-threatening Clostridioides difficile (C. difficile) – the major cause of antibiotic-associated diarrhea. The treatment makes it possible for people to recover from this destructive infection and holds tremendous potential in the care of various other serious diseases.

John is fascinated by and invested in this exciting new frontier in medicine – both as a donor and as a microbiology and immunology graduate student at Western University, who is training at Lawson Health Research Institute’s Canadian Centre for Human Microbiome and Probiotics at St. Joseph’s Hospital. He is among those working to unravel the mysteries of the human microbiome to improve health and health care.

Dr. Michael Silverman, Medical Director of St. Joseph’s Infectious Diseases Care Program, is a fecal transplant pioneer who has have played a key role in the treatment becoming the standard of best practice for C. difficile across Canada and the USA.

“As a grad student, when I heard how effective fecal transplants are for C. difficile and how many trials are going on related directly to patient care for various illnesses, I thought I had to help out,” says John, who became a donor in 2018. 

For many patients struggling with C. difficile, fecal transplants are critical, explains Dr. Michael Silverman, Medical Director of St. Joseph’s Infectious Diseases Care Program who has been performing the procedure since 2003 and was one of the first in North America to do so. Having published extensively on the development and safety of fecal transplantation, and most recently on how to perform it safely in the setting of COVID-19, Dr. Silverman and his team have played a key role in the treatment becoming the standard of best practice for C. difficile across Canada and the USA.

Most cases of C. difficile occur in individuals who are taking antibiotics and some acquire it while hospitalized. Antibiotics can destroy the normal bacteria found in the gut, causing C. difficile bacteria to overgrow. When this occurs, the C. difficile bacteria produce toxins, which can damage the bowel and cause diarrhea and other severe complications. Treating C. difficile with antibiotics also kills even more of the helpful normal gut bacteria, and when these antibiotics are stopped the C. difficile returns. This can happen over and over again, making treating relapsing C. difficile a significant challenge.

At St. Joseph’s, however, C. difficile patients are being cured. The success rate of fecal transplants performed by the Infectious Diseases Care Program is a staggering 96 per cent. The program is one of few centres performing the procedure as part of routine care for C. difficile, and it’s the only program in Ontario – one of two in Canada - administering the treatment via capsules.

Seema Nair Parvathy (PhD), Research Coordinator with Lawson Health Research Institute, holds up fecal transplant capsules being used at St. Joseph’s Health Care London to treat patients with C. difficile and to study their potential use for many other health conditions.

“Many patients we treat have been ill with multiple episodes of diarrhea or chronic unremitting diarrhea for many months to years, with multiple hospitalizations,” explains Dr. Silverman. “Many have lost weight and become malnourished and frail. They often are fearful that they could die and indeed 15 per cent of hospitalized patients with C. difficile do succumb to the illness.”

Patients are “delighted” when they see a dramatic improvement in their health and wellbeing after one dose of capsules, adds Dr. Silverman. “For many patients there is really no other alternative except lifelong antibiotics.”

Katharine Gorjup, 62, is among those delighted patients. In October 2021, a dental infection requiring intravenous antibiotics triggered C. difficile so severe her weight dropped to 90 pounds. At 5’ 8”, she became skeletal and unable to care for herself. Her condition went undiagnosed for four months.

“I looked like I was dying and that’s how I felt. I couldn’t cope. It was never-ending. I begged to get care.  I thought I might poop myself to death,” said the Etobicoke woman, whose bathroom humour is intact despite her ordeal.  

With COVID-19 in full swing, Katharine, who was simultaneously dealing with unrelated treatment for anal cancer, had difficulty getting care. She ended up on antibiotics that had to be continually increased, caused various side effects, and was costing $300 a month even with drug coverage. The diarrhea would make a raging return with every attempt to reduce the medication. After six months with crippling C. difficile and little hope, Katherine came to St. Joseph’s, the only centre in Ontario offering the procedure during the height of the pandemic.

St. Joseph’s Health Care London is the only hospital in Ontario – and one of only two in Canada - administering life-saving fecal transplants via capsules. Just one treatment is curing patients with debilitating and deadly C. difficile.

It took one treatment.

“Within three days, I started to feel better. My life is now back on track. I had a normal poop today – I’m so stoked!  I’m good every day. Hallelujah!

Such life-changing stories are common for C. difficile patients who undergo fecal transplants, yet others are left suffering. There is a serious shortage of donors. Criteria requiring only very healthy donors, the ‘ick factor’ often associated with donating poop, and the pandemic has created a poop supply crisis.

“Our need for local donors is very great,” says Dr. Silverman. “COVID-19 has made the maintenance of donors in the program extremely difficult. When a donor gets COVID they cannot safely donate for three months. Donations also have to be put on hold after donors travel to tropical countries where bowel infections are common, until we can retest their stool and assure it is safe to donate again.”

At times, there have been no eligible donors and the team has had to stop treating vulnerable patients, says Dr. Silverman.

“We critically need healthy donors in London to come forward.”

John usually donates a few times a month and more often when clinical trials are underway. In a pinch, he’s been known to donate on demand, although he usually gets a day or two notice. While he is currently on hold due to a recent bout of COVID-19, John says the donation process is easy and people need to get past the optics.

“It’s mind boggling for most people but the more donors we have, the more we can do. We need donors to fuel this exciting and expanding area of research, and to save lives.”

The future of fecal transplants

There is still much to learn about the human microbiome and its role in fighting disease, but ongoing studies at Lawson Health Research Institute, including a focus on fecal microbial transplants (FMT), are making strides in harnessing this complex system. The tremendous potential of FMT is being studied in connection with conditions as varied as non-alcoholic fatty liver disease, rheumatoid arthritis, atherosclerosis, HIV, cancer and multiple sclerosis.

The scoop on fecal transplants

What is fecal transplantation?

Fecal transplantation involves collecting feces, also called stool or poop, from a carefully screened, healthy donor. In the lab, it is mixed it with saline solution, then filtered. The finished product contains the good bacteria in a liquid or capsule format, which is then introduced into a patient’s gastrointestinal tract.

Why are fecal transplants performed for C. difficile?

The goal of fecal transplants is to transplant the donor’s microbiome so that healthy bacteria will colonize in the patient’s gut. A healthy digestive tract has thousands of different types of bacteria. In most cases, these bacteria are helpful for digestion, or are harmless. However, treatment with antibiotics, which may be required for certain conditions, can kill off many of the good bacteria in the colon. This can allow the bad bacteria, called Clostridioides difficile (C. difficile) to take over. A fecal transplant supplies the healthy bacteria that suppress the C. difficile, thus controlling the infection and keeping it from coming back.

What’s the fecal transplant process for patients?

Eligible patients have been treated several times for C. difficile, may have been hospitalized for the infection, and are on an antibiotic, Vancomycin, for a prolonged period to prevent relapse.

  • Fecal transplants are most commonly performed through a series of rectal enemas or via a colonoscopy performed under sedation with the solution containing the donor poop delivered via a tube into the colon. At St. Joseph’s, however, the team has perfected the delivery of fecal transplantation by way of capsules that the patient swallows. St. Joseph’s is the only centre in Ontario using this much simpler and patient-friendly process. Capsules are opaque and there is no smell.
  • Patients need only one treatment, which involves taking 30 to 40 capsules over 45 minutes. The patient is observed in the clinic for 30 minutes and then goes home.
How poop saves lives

It's in you to become a poop donor

Screening: To become the perfect poop donor requires an extensive screening process. Donors must be in excellent health and live a healthy lifestyle. A thorough review of the donor’s health and medical history will be done, including, stool, urine and blood testing. Donors should also reside in London.

Collection: A special container is provided to donors by St. Joseph’s to collect their poop. There are various ways to make collection easy and the donor can choose what works best for them.

Drop off: Donors bring their stools to St. Joseph’s Hospital. Most people poop in the morning and so they bring it fresh that morning. If they defecate in the evening, the poop can be kept in a refrigerator overnight (not more than 12 hours) and brought in in the morning.  Upon drop off, donors have a nasal swab done to test for COVID-19.

Payment possibility: Donors contributing to the program are paid $50 in cash per drop off to cover parking and any travel expenses.
