Yersinia (enterocolitica) antibodies connected hashimoto's?

I have Yersinia antibodies or more so had them 10 years ago , don't know current status.

Was surfing around and found some studies that yersiniosis can trigger hashimoto's .

I was tested (2004)by a psychiatrist and no sign of recent infection found from stool buy from blood , she figured I have had it around the time my knee got inflamed (1993). So she figured as it was untreated stomach bug it went to joints. Nobody even looked for it back then.

So has anyone else had yersinia antibodies and that triggered hashimoto?

( I guess I am just trying to figure out what triggered my illness so I could accept it or maybe I could build a solid case to present to a doctor to get me tested properly)

Which bacteria have been associated with triggering Hashimoto’s?

A variety of bacterial infections have been implicated in triggering autoimmune thyroiditis, including Helicobacter Pylori (the same bacteria that causes ulcers), Borrelia burgdorferi (associated with Lyme disease) and Yersinia enterocolitica.

Antibodies to Yersinia (indicating exposure) in people with Hashimoto’s were found fourteen times more often than in people without Hashimoto’s. Yersinia membranes contain a site that binds TSH, making it a prime suspect based on the molecular mimicry theory. Infection with this bacteria can induce antibodies against sites that recognize and stimulate TSH receptors, like the thyroid peroxidase enzyme or thyroglobulin.

People can contract a Yersinia enterocolitica infection from contaminated meat, poultry, dairy products, and seafood (especially oysters). In 2012, a consumer group found that 67% of pork sold in the U.S. was contaminated with Yersinia!!


Thanks for the link Clutter! I knew h.pylori and borrelia as possible causes but never figured yersinia could be one.

Now I can pester doctors with proper info :D
