I've been learning about body flora for an assignment and I have been running into a term "microflora" in many places. From what I understand, scientists use microflora when they talk about any microscopic organisms that make up our body flora.
The most interesting one I've read about is the microflora of the intestines because most of the bacteria we have in our body is actually in the large intestines.
Scientists study microflora of the intestines because they say that if there is a disruption or imbalance in it, then the likeliness of becoming ill becomes high. For example, if we use a lot of antibiotics or if we are extremely worried about hygiene and use antibacterials a lot, we can disturb the microflora. Our digestive system might not work properly, or we might get sick more than usual.
So scientist have to know what the microflora of a body system, like the intestines, should be like and how they can get it back to normal if there is a problem.
