Interactions Between Microorganisms and Animals

A mixture or a group of organism that commonly found at any anatomical site is referred to as the normal flora. In a healthy animal blood, brain and muscle are normally not affected by normal flora but the surface tissues like skin and mucous are constantly exposed. Normal flora of humans is complex it varies according to age, sex, diet and nutrition. Microbial association with skin is mainly due to staphylococci and Corynebacteria. These two are considered as non pathogenic.It has some parasitic and mutalistic roles too, it produce fatty acid that inhibit the growth of fungi and yeast in the skin
