Causes and spread of infection

1.1 Identify the differences between bacteria, viruses fungi and parasites
Bacteria: A bacteria is a single cellphoneed existence that is essential for solely life. They be either a parasite or harp independently. Bacteria have three basic shapes that involve spiral, cocci and bacillus. Bacteria multiply themselves by cell division. Antibiotics can normally kill them. An example of bacteria is meningitis and pneumonia.
Fungi: A fungus is a spore producing existence that has no chlorophyll and can live as single celled yeast or as a bigger multi-cellular mould. It will reproduce by spores. It will live by absorbing certain nutrients from any organic matter. Fungi include moulds, mildews, mushrooms and yeasts. Fungi can cause unsoundness in resistant suppressed mountain, such as jock itch and ringworm. Penicillin is do from a fungus.

Viruses: Viruses are microscopically small and are the simplest microbiological entity. A virus is not an independent living organism and inevitably a host cell to replicate. They are sub-microscopic parasitic particles of nucleic vinegarish (RNA or DNA) that are wrapped in protein. Viruses are resistive to antibiotics and are spread in the air or by direct contact. They can lead to serious or sometimes deadly diseases, such as AIDS.



Parasites:

Parasite: parasite is an organism that lives on or inside another organism to the scathe of the host organism.
These are of various forms and types. A parasite is an organism that lives on or in a host and gets its fodder from or at the expense of its host. Parasites can cause disease in humans. Some parasitic diseases are easily inured and some are not. The burden of these diseases often rests on communities in the tropics and subtropics, but parasitic infections also affect people in developed countries. 

Bacteria, fungi and viruses are all genuinely different from one another. A big difference is what cell coating they have surrounding their cells. Bacterial cell walls are made of...If you want to get a full essay, tell it on our website: Ordercustompaper.com
