It has been discovered that this type of cell is found in humans and is more numerous in humans than there are human cells themselves. most of these are beneficial and aid in processes such as digestion and disease fighting, although some of them can be pathogenic. which of these types of cells is described here?

The answer is microbial cells.

It is known that microorganisms live in gastrointestinal tract, in saliva, oral mucosa, and in deep layers of the skin. Some of them are pathogens (Streptococcus, Salmonella, etc.), but some can help in digestion (firmicutes, Bacterioidetes, etc.) or disease fighting. At first, it was proposed that there are 10 times more microorganisms than human cells in a human body. But latest research showed that the ratio is 2:1 in behoof of microorganisms, even closer to the ratio 1:1.
