How does Helicobacter pylori cause stomach ulcers?
A) Fimbriae enable to bacteria to penetrate the mucosa and bind to the epithelial lining of the stomach where toxins are released that bind and destroy epithelial cells.
B) The glycocalyx protects the bacteria from stomach acid as the bacteria enters a susceptible host and binds to an area of epithelial cells in the stomach with thin mucosa where toxins cause further damage and allow entry.
C) Polar flagella help bacteria burrow into mucosal lining to escape stomach acid, where enzymes decrease the acidity around them, and they release a toxin to kill host cells.
D) Peritrichous flagella help the bacteria squeeze through the mucosal lining to avoid stomach acid, where cytokine imposters are released which attract B cells and cause the immune response to destroy the epithelial lining of the stomach.
E) Bacterial capsules allow the bacteria to survive in the acidic lumen of the stomach as it releases toxins that bind to and destroy the epithelial lining of the stomach.
