Researchers discover how chlamydiae multiply in human cells
Chlamydia are bacteria that cause venereal diseases. In humans, they can only survive if they enter the cells. This is the only place where they find the necessary metabolites for their reproduction. And this happens in a relatively simple way: The bacteria create a small bubble in the cell and divide in it over several generations.
