Part both of the essay will focus on indigenous micro vegetation that is on and in the body, and part three will describe the expression and replication procedure of viruses.Part oneAs stated by Prescott, Harley and Klein (1990) microbiology is the study of organisms that are usually t oo petite to be seen with the nude eye.According to Jenson and Wright (1989) a pathogen is a disease-producing organism.They also describe microbes as organisms that are often too small to be seen without the aid of a microscope. Microbes, also known as microorganisms, can be broken down into foursome classifications that are bacteria, viruses, fungi, and protozoa. Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in structure they usually are between o.5 and 5cmm up to now they have many characteristic shapes and sizes. Some bacteria are rotund or oval shaped, they are known as cocci bacteria. other(a) bacteria are rod-shaped, they are known as bacilli bacteria, and some bacteria are spiral and coil-shaped and it is know as spirilla bacteria.Engelkirk & Burton (1979) state that bacteria can reproduce asexually by simple division of cells and some bacteria reproduce sex ually by conjunction. A bacterium is a waste producer of products and secretions. This allows pathogens to invade their hosts to cause disease some of these pestilential diseases are Scarlet fever, an acute illness, characterized by a reddish pare down rash, which is caused by systematic infection with the bacterium streptococcus.
