Viruses attach themselves to other organisms and severe infectious diseases. * Fungi are a group of simple plants whose cells are devoid of chlorophyll‚ fungus has chitis in its cell walls instead of cellulose. Fungi are popular for beneficial effects including food production‚ penicillin production and decomposition. * Parasites are those micro-organisms(hosts) for their survival both virus

Throughout the world there are many animals‚ plants‚ fungi and numerous other living organisms that are influenced by the overall condition or adaptations of other organisms. Whether it is a symbiotic relationship or a predator/prey relationship there are many ways in which animals and other living organisms operate and live; both dependent on others and their own adaptations. The point is that there are many relationships that provide a basis and means for the survival of a variety of different

properties. The five basic properties are: cellular organization‚ metabolism‚ homeostasis‚ growth and reproduction‚ and heredity. Biologists have assigned all living things to six groups called Kingdoms. The six kingdoms are Archaea‚ Bacteria‚ Protista‚ Fungi‚ Plantae‚ and Animalia. Archaea is the kingdom of prokaryotes; simple cells that don’t have nuclei; they include methanogen‚ which fabricates methane. Bacteria are second in the prokaryotes‚ they are typically a few micrometers in length and

Advances in modern science have had great impacts on our ability to understand how matter and energy cycle throughout systems. The cycling throughout networks can be explained by the Law of Conservation of Matter and Energy‚ which states that matter and energy cannot be created or destroyed‚ only changed. This cycle applies to many things‚ such as energy cycling through a food web‚ carbon traveling through the biosphere in the carbon cycle‚ and the movement of energy and materials that are used during

Infection Control in the Workplace Every health care worker plays a vital part in helping to minimise the risk of cross infection – for example‚ by making certain that hands are properly washed‚ the clinical environment is as clean as possible‚ ensuring knowledge and skills are continually updated and by educating patients and visitors. Standard precautions (formerly known as universal precautions) underpin routine safe practice‚ protecting both staff and our residents from infection. By applying

The causes of infection. Diseases can be classified as genetic‚ metabolic‚ or infectious. Infectious diseases are caused by bacteria‚ viruses‚ fungi and parasites that use our body as a host for reproduction and cause illness. Bacteria‚ viruses‚ fungi and parasites. These are all microorganisms which cause infection‚ yet they are all different in structure‚ required environment and conditions needed to thrive and multiply. Bacteria is a single celled organism.

CHAPTER 1 Introduction and Its Background Introduction Infectious diseases are one of the main contributors to global mortality and morbidity. Infectious diseases are caused by pathogenic microorganisms‚ such as bacteria‚ viruses‚ parasites or fungi. These diseases can be spread‚ directly or indirectly‚ from one person to another. Vaccines‚ antibiotics‚ and many other advances have lessened the impact of infectious diseases. Unfortunately‚ this has not been true everywhere. It has not been true in
