the estimate for the entire body was thus 100 trillion bacteria. In 1977, Professor Savage's team compared this number to that of human cells (10 trillion), arriving at the now-famous ratio.

Just as the human body serves as a habitat for bacteria and other microbes, diverse, tiny organisms known as protists host ...

In a breakthrough for the advanced study of gut health, NUS scientists have developed a 3D microscopic version of the human ...

Inside the human body, the immune system is confronted with a similar threat from microbial tricksters that seek to breach the body’s defenses to perpetuate their own survival. To move stealthily ...

This complex microbial dance seems to have a really important role in our health. Oral diseases and even oral cancers have ...

Now a new Northwestern University study points to the role of gut microbes. From Anatomy of the Human Body. Image by Henry Vandyke Carter. Creative Commons 3.0. In a controlled lab experiment ...

They found these obelisks in the gut, mouths, and even in human stool, from people on different continents. Many of these obelisks only loosely resembled each other, so there are likely different ...

In new research published this week, a team led by Marine Biological Laboratory (MBL) scientists reveals that symbiotic bacteria often accompany single-celled protists in the ocean’s upper layer. Some ...

This interplay highlights how gut microbes interact with the host body in a dynamic, give-and-take relationship." Importantly, BA-MCYs were also detected in human blood samples, indicating that ...

as in the human gut, mimics key structural and physiological features of the gut lining, allows for diverse communities of microbes to be cultivated, and is designed for easy and real-time ...

Antibiotics are a double-edged sword—they should be as toxic as possible to pathogenic bacteria while being harmless to the cells of the human body. An international research team led by the ...
