Microbes, also known as microorganisms, can be broken down into four classifications that are bacteria, viruses, fungi, and protozoa. Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane cover nucleus). Bacteria are both small and simple in structure they usually are between o.5 and 5cmm yet they have many singularity shapes and sizes. Some bacteria are circular or oval shaped, they are known as cocci bacteria. Other 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 sexually by conjunction. A bacterium is a waste producer of products and secretions. This allows pathogens to encounter their hosts to cause disease some of these harmful diseases are Scarlet fever, an slap-up illness, characterized by a reddish skin rash, which is caused by systematic transmittal with the bacterium streptococcus.
