Question # 1

How the structure and function of pathogens help to prevent diseases?

The bacteria of pathogens have several characteristics and feature that they require for using and causing disease. Such virulence factors have particular functions in producing an infection in the body. An infection may be understood as a minute combat that occurs between the host and bacteria as the bacteria is making efforts to remain live and to get feed and multiply, whereas the host makes efforts to prevent the survival of those bacteria.

Bacteria have so many distinctive strategies for making an individual ill and cause disease. Such strategies are regarded as the bacterial pathogenicity and such are the course of a significant distribution of the microbiology in the medical. For better understanding of the fact that how a specific bacteria makes an individual ill and cause diseases can end result in better prevention, treatment, or vaccination of that disease that cause by the infection of bacteria. For this purpose, it is highly important to completely comprehend the functions and structure of specific infectious bacteria that cause the disease as by knowing the function of those bacteria with which they produce harm and damage in a body can be counterpart by the suitable medication and treatment (Johnson, 2006, p. 115). And, simultaneously by better understand the structure of such pathogens can help a medical practitioner or physician to design his or her treatment plan or medication doses in accordance with the potential of such pathogens so that, the medication could be affected over such pathogens.

Uses of Bacteria

Helps in making agrichemicals and pharmaceuticals

Can be used in genetics, biochemistry, and in molecular biology

Used for producing insulin, antibodies, and other growth factors in the field of biotechnology

Some bacteria are friendly and live in our intestines for better digestion and immune health

Used in making fertilizers that protects our crops

In coming times, it can be helpful in producing fossils fuel free electricity



Question # 2

Main groups of Micro-organisms and their commercial importance and harm

Bacteria

Nitrogen fixed bacteria helps to increase the soil fertility by nitrogen processing in the soil. They are beneficial for our health as they produce a type of vitamin in the body and used in the production of anti-bacterial medicines.

Bacteria cause gastrointestinal infection and hence cause indigestion in the body. They can enter in the body and can causes several serious diseases and if enters in the food items then such food spoils for eating and can make a person ill. Examples are Proteus and Escherichia coli.

Fungi

The fungal spores are more constant than somatic cell and provide homogeneous suspensions for providing substrate conversion. It requires a simple medium for expansion and its by-products very rare. Germ-tube can be repressed without having any effect on efficiency of the transformation of chemical.

Virus

Virus has been increasingly used in the research of genetics and in the genes understanding as well as in the replication of DNA, formation of RNA, formation of protein and other ...
