Homo sapiens or homo bacteriens?

Homo sapiens or homo bacteriens?

Man is called homo sapiens, but judging by the huge amount of bacteria living in our bodies, homo bacteriens would have been a perfectly suitable name too.

Picture this: we have 10 trillion human cells (or eukaryotic cells) in our bodies, which is a lot. But we have even more bacterial cells (or prokaryotic cells). It’s estimated we have as many as 30-50 trillion bacterial cells. These trillions of bacterial cells make up over 1000 species that live in and on our body.

This raises a fundamental question: why doesn’t this enormous bacterial population cause continuous infections in our body, as they contain one of the most potent pro-inflammatory components (LPS)?
