MODULE Normal Flora of Human Body Microbiology 78 Notes 7 NORMAL FLORA OF HUMAN BODY 7.1 INTRODUCTION In a healthy human, the internal tissues, e.g. blood, brain, muscle, etc., are normally free of microorganisms. However, the surface tissues, i.e., skin and mucous membranes, are constantly in contact with environmental organisms and The normal microbiota are the microbes typically found in healthy people. These microbes are present at various places in the body and may be pathogenic (capable of causing disease) but are not in the process of doing so.

what is the microbiome (microbiota) or normal flora وللمزيد تفضلوا سلسلة اسرار التفوق الدراسي 2021-04-08 · Microbial flora of the stomach and gastrointestinal tract The stomach and gastrointestinal tract are not sterile and are colonized by microorganisms that perform functions beneficial to the host, including the manufacture of essential vitamins, and the prevention of colonization by undesirable microbes. Microbiota refers to the interacting microbes in a given environment (microbiome is their living genome sequencing).

Normal flora of human host: Types, Examples and Roles. Microorganisms associated with healthy tissue of host semi-permanently without causing disease are known as Normal flora or Microbial flora or Human microbiota. All human tissue which are directly or indirectly exposed to external surrounding have normal flora. Oral administration of antibiotics for treatment of urinary tract infections (UTIs) can cause ecological disturbances in the normal intestinal microflora. Poorly absorbed drugs can reach the colon in active form, suppress susceptible microorganisms and disturb the ecological balance.

Below the bladder, the normal microbiota of the male urogenital system is found primarily within the distal urethra and includes bacterial species that are commonly associated with the skin microbiota- think Staphylococcus. In women, the normal microbiota is found within the distal one third of the urethra and the vagina. The mixture of organisms regularly found at any anatomical site is referred to as the normal flora, except by researchers in the field who prefer the term "indigenous microbiota". The normal flora of humans consists of a few eucaryotic fungi and protists, but bacteria are the most numerous and obvious microbial components of the normal flora.

The normal flora of microorganisms is consisting of eukaryotic fungi, protists, bacteria, etc.

Microbiota is established by age 3, however as we age, factors like where we live, diet, drugs such as antibiotics, alcohol and stress can all destroy our gut flora. It has been estimated that there are more microbial cells inhabiting the human body than there are eukaryotic cells of which it is made up. This normal microflora usually co-exists relatively peacefully with the host and does not cause infection.
