Summary Introduction

Introduction:

Microorganisms like bacteria, fungi, protozoa, and viruses are present either in the form of single-cell or clusters of cells. The human body is occupied with various non-pathogenic strains of normal microflora which prevents the entry of pathogenic microbes. Any deviation from the normal living condition of microflora results in the reduction of their population and this could lead to various diseases.
