This ecosystem can be clustered into groups dominated by one of the crispatus, iners, gasseri, or jensenii species of a certain genus or by other anaerobic species. During this ecosystem’s development, deposition of glycogen in its surroundings facilitates acidification and colonization. Nugent scores characterize a dysbiosis of this ecosystem (-5[1])that can be corrected with metronidazole gel. (10[1]-5[1])That dysbiosis (-5[1])of this ecosystem (-5[1])occurs (10[1])when Atopobium, Prevotella, or Gardnerella (-5[1])species (-5[1])form biofilms that replace normal (-5[1])inhabitants. Boric acid capsules (10[1])prevent the overgrowth of Candida (-5[2])in this ecosystem, (10[1]-5[4])which may be triggered by antibiotic (-5[1])use. (-5[3])A discouraged “seeding” procedure exposes C-section infants to this ecosystem, (10[1]-5[1])which they otherwise would not contact. (-5[1])For 10 points, name this Lactobacillus-dominated environment that maintains the acidic conditions of a major reproductive structure. (10[1]0[1])■END■ (10[5]0[9])
