CU254 Causes and Spread of Infection 1.1Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 1.2 Identify

CU254 Causes and spread of infection. 1.1 Viruses are pieces of nucleic acid wrapped in a thin coat of protein that replicate only within cells of living host. Bacteria are one cell micro-organisms with simple cellular organizations whose nucleus lacks a membrane. Parasites may be protozoa‚ yeast or multi cellular organisms such as fungi or worms that live in or on a host to obtain nourishment without providing any benefit to the host. Fungi there are many different varieties of fungi‚ and

IC02 Causes and spread of infection The difference between bacteria‚ viruses‚ fungi and parasites are: Viruses are coated genetic material that invade cells and use the cell’s apparatus for reproduction. Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life. Fungi are multi-celled organisms that form a third Kingdom of life‚ along with the plant kingdom and the animal kingdom. Parasites are plants or animals that derive benefit
Premium Bacteria Infection
Causes and spread of infection Micro-organisms that cause infections are known as pathogens. They may be classified as follows: Bacteria: minute organisms about one-thousandth to five-thousandths of a millimetre in diameter. They are susceptible to a greater or lesser extent to antibiotics. Viruses: much smaller than bacteria and although they may survive outside the body for a time they can only grow inside cells of the body. Viruses are not susceptible to antibiotics‚ but there are a few

Unit 265 Outcome 1 1.1 A: Bacteria: Bacteria exist everywhere‚ inside and on our bodies. Most of them are completely harmless and some of them are very useful. But some bacteria can cause diseases‚ either because they end up in the wrong place in the body or simply because they are ’designed’ to invade us. Bacteria can infect humans‚ plants or animals. B: Viruses: A virus is a small infectious agent‚ too small to be seen by the naked eye. They can’t multiply on their own‚ only inside the cells of

Causes and spread of infection. Bacteria. These organisms are made up of just one cell. They have the power to divide so can multiply on their own. Some bacteria are harmless and can be of use in the aid of digestion and are found in the intestines. Other bacteria can be the cause of diseases. These bacteria have to find a way in to the body to be of harm and can make their way through the skin or be digested and attack our immune system. Viruses. These micro-organisms are very tiny. They invade

unit 4222- 265 1 1.1: identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria are living things that are neither plants nor animals‚ but belong to a group all by themselves. They are very small--individually not more than one single cell--however there are normally millions of them together‚ for they can multiply really fast.Bacteria are prokaryotes (single cells that do not contain a nucleus). Every species has a great ability to produce offspring and its population

Unit 4222-265 Causes and spread of infection (ICO2) 1.1 Identify the differences between bacteria‚ viruses‚ fungi & parasites. • Bacteria is a microorganism‚ most bacteria is harmless. It is found in soil‚ water‚ plants‚ animals and humans; it can only be seen under a microscope. Antibiotics can help treat bacterial infections. Examples of bacterial infections are TB and MRSA. • Viruses live inside other living organisms. They can enter humans through the nose‚ mouth and breaks in the skin. Viruses

How Are Infections Spread? Alicia Todd University of Mobile How Are Infections Spread? According to Lynch‚ Elmore and Morgan (2012)‚ millions of people die each year from infectious diseases such as influenza‚ malaria‚ tuberculosis‚ and acquired immunodeficiency syndrome (p. 245). Everything we eat‚ breathe‚ or touch throughout the day puts us at risk for developing an infection. Knowing how infections are spread will decrease these risks and is crucial for overall health. No matter how hard one
