2009-07-11 Bacterial cells forming part of the normal flora outnumber human cells in the body. The normal flora provides protection by competing with pathogens for colonization sites and producing antibiotic substances (bacteriocins) that suppress other bacteria. Recent evidence also suggest that bacterial flora can modulate the function of the intestinal mucosal cells. These observations support the role of the intestinal bacterial flora in the induction of an uncontrolled inflammation in the human gut, leading to tissue damage. In most healthy women in the reproductive period the predominant vaginal bacteria are one or more of the following species of Lactobacillus: L. crispatus, L. ine ….

The normal flora prevent colonization by pathogens by competing for attachment 3. and normal function zResident flora is believed to prevent colonization by pathogens and possible disease through bacterial interference. zMembers of normal flora may themselves produce disease under certain circumstances and if removed from the restrictions of that environment and introduced into the bloodstream or tissues, these organisms may become Normal flora of the conjunctiva: Organisms like diphtheroids, epidermidis and non-hemolytic streptococci form the conjunctival microbial flora. Similarly, Neisseriae and Moraxella species are also frequently present. Tear contains antibacterial substance called lysozyme that holds the check in the conjunctival flora.

The mouth is a favorable habitat for a variety of bacteria. Oral bacteria include streptococci, lactobacilli, staphylococci and corynebacteria, with a great number of anaerobes, The functions of the normal flora include digestion of substrates, production of vitamins, stimulation of cell maturation, stimulation of the immune system, aid in intestinal transit and Resident flora has two main protective functions: Normal bacterial flora on hands.

Certain microorganisms perform tasks that are known to be useful to the human host but the role of most of them is not well understood. Those that are expected to be present, and that under normal circumstances do not cause disease, are sometimes deemed normal flora or normal microbiota. Normal Bacterial Microbiome Oral bacteria may serve several important physiological functions in addition to playing a critical role in periodontal disease, tooth loss, and possibly gastrointestinal cancers (Ahn et al., 2012; Pihlstrom et al., 2005). Bacteria that are normal constituents of the vaginal flora of the host have the potential to cause symptoms of disease, but they apparently require some alteration in the microenvironment to do so.
