Abstract
Aims: To describe the existence of microbial normal flora and its contribution to homeostasis, with emphasize on several major systems of the human body.
Discussion: Normal microflora are a group of various microorganisms that reside in the bodies of all humans or animals. These organisms are consistently exist, and relatively stable, with specific genera populating various body regions during particular periods in an individual's life, from shortly after birth until death. The indigeneous normal microbiota provides a first line of defense against microbial pathogens, assists in digestion, and contributes to maturation of the immune system and in general able to assists the anatomy, physiology, susceptibility to pathogens, and even morbidity of the host. Several internal factors like age and external factors like geographical position, diets habbits, the condition of stress, infection and even antibiotics consumption, are some factors that can affect the function of normal microflora.
Conclusion: Normal microbial microflora consistently inhabits some region of the body and influences the hots’s homeostasis. Several factors such as diets, stress, infection and antibiotics administration, can affect the existence and performance of normal microflora.
