*Streptococci can cause pneumonia *Acinetobacter can cause bacteria meningitis if it gets into blood stream *Corynebacterium *Neisseria can cause meningitis. *Candiida causes thrush. |

The role of bacteria in tooth decay
|
*Steptococcus mtans attaches to a protein film (pellicle) and forms a biofilm which it lives, protect itself and capture nutrients.
*Nocardia and Neisseria are aerobic bacteria *S. mutans are facultatively anaerobic: when all the oxygen is used up by Nocardia and Neisseria, S. mutains is able to metabolize anaerobicall. * when S.mutans metabolizes anaerobically, the lactic acid byproduct lowers the pH of the area, which is responsible for the degradation of the calcium phosphate of the tooth. |

How helicobacter plyori causes ulchers
|
Bacterium secretes several proteins that erode the lining of the stomach. . hemolysin, is screted by the cells and causes release of hemoglobin. hemoglobin is coverted to hemin and urea. urea is broken down to ammonia. ammonia is basic, which creates a pH of about 7 for the bacterium to thrive..
