Introduction
As we all know, bacteria is a very complex organism and the subject can be very broad. In this essay, the focus will be on bacteria and the bacterial cell structure. Different forms of bacteria, its pros and cons, the cell structure, diseases and resistance will be explained and listed. First bacteria and cell structure is explained, and then moving on to different bacterial forms and diseases, and how diseases can be prevented or even cured. Then finishing the essay will be the conclusion.

Bacteria
The bacteria are one of the six municipalities of living. Bacteria are single-celled microbes, or small organisms. Bacteria are prokaryotic, which means that they do not have a nuclear membrane around the genetic material. With the exception of Ribosomes, bacteria do not have cell bodies. Bacteria are very quick to reproduce; for example, the most studied one E. coli can in favorable circumstances divide every 20 minutes. Thanks to its rapid ability to divide, bacteria are very quick to adapt to changing living conditions. Although the structure is simple, their metabolites may be highly developed and specialized. Thus, the bacteria can use virtually any organic structure. [1][2]

Bacteria as pathogens
Although they are the smallest cells in biocoenosis, their role is even more important. Some bacteria are even able to assimilate (e.g. cyanobacteria or "blue-green algae"). Some of the bacteria decays or rots other organisms to feed themselves. This also benefits
