Microbiology视频慕课课程简介：

There is a world of microorganisms on earth that is hard to see with our eyes. It has a long history, but the individual is small, and it was not seen by humans through a microscope until the mid-17th century. Small microbes contain huge energy, they are everywhere and omnipotent. They are both "angels" and "devils". If you are interested, please join the "Microbiology" course and explore the mysteries of "Little People" together.
