Lactobacillus Dominance in the Healthy Vaginal Niche
Placeholder: Lactobacillus species normally dominate a healthy vaginal microbiome.
- Lactobacillus: Dominant genus (Placeholder short note)
- 3.8–4.5: Typical pH (Placeholder short note)
- Low: Species diversity (Placeholder short note)
- Dense: Colonization (Placeholder short note)
Why Lactobacillus dominates
Placeholder: a short sentence on niche exclusion by Lactobacillus.
Lactic Acid Production Maintains Low Vaginal pH
Placeholder: Lactic acid byproduct keeps the environment acidic and protective.
- Lactic acid: Main acid (Placeholder short note)
- Present: H2O2 output (Placeholder short note)
- Produced: Bacteriocins (Placeholder short note)
- High: Protective effect (Placeholder short note)
Acid as a chemical barrier
Placeholder: a short sentence on acid inhibiting pathogens.
Antibiotics, Douching, and Sexual Contact as Disruption Factors
Placeholder: External factors can disturb the acid-producing balance.
- Kill Lactobacilli: Antibiotics (Placeholder short note)
- Flushes flora: Douching (Placeholder short note)
- ~7.2: Semen pH (Placeholder short note)
- Days–weeks: Recovery time (Placeholder short note)
How disruptors act
Placeholder: a short sentence on mechanisms of each disruptor.
Rising pH Enables Pathogenic Bacterial Overgrowth
Placeholder: As pH rises, pathogenic species outcompete Lactobacillus.
- >4.5: pH shift (Placeholder short note)
- Rapid: Pathogen growth (Placeholder short note)
- BV-like state: Common outcome (Placeholder short note)
- Variable: Symptom onset (Placeholder short note)
The dysbiosis cascade
Placeholder: a short sentence on pathogen overgrowth dynamics.
Two Trajectories: Natural Recovery or Sustained Dysbiosis
Placeholder: outcome depends on residual Lactobacillus and disruption removal.
- Residual flora: Recovery driver (Placeholder short note)
- BV / candidiasis: Infection risk (Placeholder short note)
- Supportive: Probiotic role (Placeholder short note)
- Days–months: Timeframe (Placeholder short note)
What determines the outcome
Placeholder: a short sentence on recovery versus chronic dysbiosis.
