Normal Flora on the Body — Interactive Simulation

Click a body region to inspect its normal flora balance. Change conditions (diet, antibiotics, hygiene, humidity, immunity), then use the IBL Follow-Up section to record evidence-based explanations. High-contrast mode is enabled so questions and suggestions are easy to read.

Change Conditions

These sliders affect all regions, but each region responds differently.

Antibiotic Exposure

Higher values reduce beneficial bacteria quickly, especially in the gut and mouth.

10%
NoneHigh

Diet Quality (Fibre / Variety)

Supports beneficial microbes in the gut, improving stability and colonisation resistance.

PoorExcellent

Hygiene Intensity (Soap / Sanitiser)

Moderate hygiene helps; extreme hygiene can disrupt skin barrier and normal flora.

50%
LowVery high

Humidity / Moisture

Moist areas (armpit, feet, urogenital) are more likely to get overgrowth if humidity is high.

55%
DryVery humid

Immune Strength

Stronger immunity keeps opportunists in check. Lower immunity increases risk across all sites.

Scenario (Optional)

Pick a scenario to auto-adjust conditions, then observe changes across regions.

Teacher prompt: Explain why gut flora changes faster with antibiotics than skin flora.
