It is estimated that there are more germ cells inhabiting the human body than the eukaryotic cells that make up. These natural bacteria usually coexist relatively peacefully with the host and do not cause infection.

The mechanisms in which this coexistence is achieved are still poorly understood, and the interaction between ordinary microflora and host is far from simple. For a variety of reasons, this interaction can be disturbed and often leads to the transformation of microorganisms into pathogens.

The subsequent study of diseases is important in terms of treatment and contributes to our understanding of the mechanisms in which normal organic plants interact normally with the host. This title brings together an international list of contributors, all of whom have active research interests in natural bacteria.

Each chapter reviews the current knowledge about a particular group or organism within the microorganisms and the diseases it can cause. The exact tissue of the skin, respiratory tract, oral cavity, digestive system and reproductive system was discussed.

The effect of molecular methods on our understanding of natural microflora was also emphasized throughout the book. Medical biologists, dentists, infectious pathologists, dietitians and gastroenterologists will find this book of great interest and value, as well as epidemiologists, dermatologists and general microbiologists..
