The physiological aerobic bacterial flora of the low male genital tract was determined. The female urethra is colonized with large number of lactobacilli, streptococcal species, and coagulase-negative staphylococci. Actinomycesisraeli is the most common Actinomyces species associated with gen-ital actinomycotic infections. Antibiotics suppress normal flora, which allows colonization and infection by naturally resistant organisms, such as Candida albicans. By continuing you agree to the use of cookies. The female reproductive tract is another organ system in which the normal microbial flora is developmentally and age related.
Normal flora of Gastrointestinal tract. With the exception of female urethra and vagina, the genito-urinary tract is generally sterile. The ureters, kidneys, prostrate, and cervix are normally sterile.
Genitourinary Tract. The remaining gram-negative urinary pathogens are usually other enterobacteria, typically Klebsiella or Proteus mirabilis , and occasionally Pseudomonas aeruginosa . pathogenic viruses, bacteria, protozoa and metazoa, Kartagener’s syndrome, cystic (BS) Developed by Therithal info, Chennai. Protective and defective roles of normal and abnormal microbial flora of the female genital tract. With the exception of female urethra and vagina, the genito-urinary tract is generally sterile. In the female genital tract lactobacilli produce lactic acid that lowers the pH, so preventing colonization by pathogens. We use cookies to help provide and enhance our service and tailor content and ads. This prospective study was performed on 600 semen specimens collected from 543 asymptomatic males consulting for infertility. Due to their proximity and overlap, these systems are often studied together and referred to as the urogenital system (or genitourinary system). They may pose the confusion with the tubercle bacilli. GI tracts consists of stomach, small intestine and large intestine. species are believed to be present in the vaginabecause they are associated with vaginal infections. Normal flora of the female reproductive system The female reproductive system (ovaries, fallopian tubes, uterus, cervix, vagina and vulva and cervix of the uterus) is normally colonised by a complex mixture of indigenous microbial flora. The aim of the present review is to describe the diverse components of both the protective and defective mechanisms induced by microbial species present in the female genital tract. Disclaimer
The microbial flora in the vagina is more numerous and diverse. With the exception of female urethra and vagina, the genito-urinary tract is generally sterile. Fecal organisms, such as, The microbial flora in the vagina is more numerous and diverse. The review summarizes that depending upon the presence and/or absence of normal and abnormal microorganisms, the female genital tract shows either a healthy and/or infectious condition. Fecal organisms, such as E. coli, Enterococcus spp., and Candida spp. The flora of the major body systems The female reproductive and urinary tract. Asian Pacific Journal of Tropical Disease, https://doi.org/10.1016/S2222-1808(16)61155-6. Bacterial flora of the female genital tract: function and immune regulation. The ureters, kidneys, prostrate, and cervix are normally sterile.

are also present in the vagina. The urinary system filters blood, excretes wastes, and maintains an appropriate electrolyte and water balance. The reproductive system is responsible for the production of gametes and participates in conception and, in females, development of offspring. Bacterial Vaginosis (BV) is a condition where the normal vaginal flora (Lactobacillus sp) is replaced with a high concentrations of anaerobic bacteria, G. vaginalis, Ureaplasma, Mycoplasma, and numerous fastidious or uncultivated anaerobes.BV is prevalent in about 20 - 25% of young women and 15% of pregnant women.
The protective mechanism was induced by indigenous microbial flora colonized in the female genital tract, which includes innate immunity, secretions containing cytokines, antimicrobial peptides and inhibitory substances like organic acids, H2O2, bacteriosin and toll-like receptors. The aerobic bacteria present in the vagina include coagulase-negative, Factors Determining the Colonization by Microbes, Normal Flora at Various Sites of the Body, Factors Affecting Hospital-Acquired Infection. antibiotic-resistant organisms, Cutaneous bacterial infection, infection with Six species of Mycoplasma and Ureaplasma are common inhabitants of vagina, which have pathogenic potential.

Microbial flora of the stomach and gastrointestinal tract.
The journal implements double-blind peer review practiced by specially invited international editorial board members. On the other hand, abnormal microorganisms produce virulence factors and enzymes, which cause life-threatening infectious diseases including cancer. Candida species and Torulopsisglabrata are common members of the microbial flora of vagina. The flagellate Trichomonas vaginalis is present in small numbers in healthy women.
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.. Normal Flora of Human Body, Skin, Respiratory Tract, Intestinal tract, Genitourinary tract, Eye Dr Adil Ramzan There are some species of bacteria and fungi that are … As the infant passes through the birth canal she picks up microorganisms representative of the adult reproductive tract. The ureters, kidneys, prostrate, and cervix are normally sterile. The aerobic bacteria present in the vagina include coagulase-negative Staphylococcus, Streptococcus (viridans group and beta-hemolytic strains), Corynebacterium spp., Gardnerella vaginalis, Neisseria spp., Haemophilus spp., and members of Enterobacteriaceae.Three species of nonpathogenic Treponema (Treponema phagede-nis, Treponema refringens, and Treponema minutum) are found invaginal specimens.
