Question
(a) why are some microorganisms specialized to only certain parts of the body?Describe an example that supports your answer.(b) How do streptokinase and coagulase promote bacteria infection and invasion?
(c) what are dental caries & explain how diet plays a role in the development of dental caries.
(d) which is the more serious condition, bacteremia or septicemia, and why?
(e) why might knowing our microbiome and how it functions be useful?
(f) explain how the gut microbiome develop/change from infancy to adulthood. How can ones diet impact the development/changes in a positive AND negative way? Will these changes have an impact on ones health?
(g) when does an infection become a disease?

Explanation / Answer
a) Microorganisms have developed defense mechanisms that can be utilized only in certain parts if the human body. Further, they contain enzymes according to the environment they inhabit. For example, Helicobacter pyroli survives in the acidic environment of stomach and duodenum.
b) Streptokinase and coagulase enzymes help in lysis of extracellular matrix thereby promoting invasion by bacteria.
c) Dental caries occur as a result of bacterial infection and it causes destruction of tooth leading to the formation of cavities. It is caused by the action of acids on enamel surface. Diet when contain sugary substances such as chocolates rich in carbohydrates such as sucrose, it reacts with bacteria present in the mouth to form plaques on dental surface leading to cavities.
d) Bacteremia is the presence of bacteria in blood. Septicemia is the presence and multiplication of bacteria in blood. Septicemia is more dangerous than bacteremia because in septicemia many bacterial toxins are produced which are potentially life threatening.
