Research on bacteria

This is the research on the bacteria that Ms Menon and Justin wanted.


Staphylococcus aureus is a spherical bacterium, frequently found in the nose and the skin of the person. About 20% of the population are long-term carriers of S.aureus. S.aureus can cause a range of illnesses from minor skin infections, such as pimples.

Escherichia Coli is a gram negative bacterium that is commonly found in the lower intestine of warm-blooded animals. Most E.Coli strains are harmless, but some can cause serious food poisoning in humans, and are occasionally responsible for costly product recalls.

Lactobacillus acidophilus is one species in the genus Lactobacillus. Some research has indicated that L. acidophilus may provide additional health benefits, including improves gastrointestinal function, a boosted immune system, and a decrease in the frequency of vaginal yeast infections. Some people report L. acidophilus provides relief for indigestion and diarrhea.
