What is Enterobacteriaceae (Gut Zoomer)? High and low values | Lab results explained

Many studies have reported an increase in the proportion of potentially harmful Proteobacteria, especially of the Enterobacteriaceae family, in IBD patients. Therefore, it would appear that the host’s inflammatory response could be the trigger of gut microbiota imbalance, most likely caused by Enterobacteriaceae blooming, which leads to the persistence of IBD’s inflammatory state.

What does it mean if your Enterobacteriaceae result is too high?

An increase is related to IBD.


Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you.
