Question

Bonnie Bassler discovered that bacteria
1 How more bacteria cells are in or on humans?

Answer 1

Bonnie Bassler is known for her pioneering work in the field of bacterial communication and quorum sensing. In terms of the number of bacterial cells in or on the human body, it is often cited that there are roughly ten times more bacterial cells than human cells.

While estimates vary, the general consensus is that the human microbiome— which includes bacteria, viruses, fungi, and other microbes— is composed of approximately 30 to 40 trillion bacterial cells, compared to about 30 trillion human cells. However, counting methodologies and definitions of what constitutes a "cell" can lead to different estimates.

It's important to emphasize that these microorganisms play crucial roles in various bodily functions, including digestion, immunity, and protection against pathogens. The study of our microbiome, including the research initiated by scientists like Bonnie Bassler, continues to reveal important insights into health and disease.
