How does H. pylori vary from helicobacter-like organisms?

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

H.pylori is Helicobacter pylori, known to be a cause of chronic gastritis and associated with peptic ulcer.

There are many species of Helicobacter found in the gastric mucosa of human beings in various studies, and many of them are found to be associated with disease or simple colonization without significant symptoms.

Helicobacter-like organisms look similar to these organisms and are detected in the gut mucosa of many mammalian animals, where they are associated with producing similar kinds of pathological changes as those caused by H.pylori.

These organisms could potentially cause disease in humans because of the proximity of pet animals to humans, allowing possible transmission.

However, they are not genetically classified within the Helicobacter group, which is why they are labeled as Helicobacter-like organisms rather than true Helicobacter species. Their exact role in human disease is still not as clearly established as that of H pylori.

However, in clinical practice, the difference matters because:

If it is clearly H. pylori, we usually go ahead and treat it. If it is helicobacter-like organisms, we take a step back and look at the whole picture, your symptoms, endoscopy findings, and overall risk, before deciding what to do.

So in simple terms, H. pylori is a confirmed culprit, while helicobacter-like organisms are more like ‘suspects’ that may or may not be causing trouble.

I hope this information helps you.
