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 008; Causes and spread of infections. Outcome 1. Understand the cause of infection: 1) Identify 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 uses 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

Bacteria multiplies by its self to progress and spread. Unlike other infections such as viruses‚ fungi or parasites bacteria is not always harmful in fact in many cases

They lives within and on most living and nonliving things. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections

UNIT 4222-265 Causes and Spread of infection (ICO2) 1) Infections are the result of the body’s inability to fight off microorganisms that can cause damage or disease if they are left untreated. They can be viral or bacterial in nature and might be caused by a fungus or parasite. There are many common types and there are some rare ones which all have varying causes and treatments. Common bacterial infections include strep throat‚ urinary tract infections and E. coli; the different types are caused

Unit 20 – Causes and Spread of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria‚ fungi and parasites are all considered as ‘living’ things‚. Bacteria are single celled microorganisms that can only been seen through a microscope‚ they collect their nutrition from their surrounding and unlike viruses‚ they do not need a living host to reproduce. Viruses are difficult to destroy because they are enclosed in a protein coating. Viruses are disease-producing

Causes and spread of infection Identify the differences between bacteria‚ viruses‚ fungi‚ parasites? -Viruses aren’t living. They’re only made of complex proteins and nucleic acids. Bacteria‚ Fungi and Parasites are living organisms. - Bacteria are unicellular microorganisms. Fungi and Parasites are multicellular. - Fungi have cell walls made of chitin and they aren’t animals. Parasites and bacteria are animals. Bacteria come in 3 main shapes; spherical which are known as cocci‚ rod shaped

Aims Causes and Spread of Infection This unit is to enable the learner to understand the causes of infection and common illnesses that may result as a consequence. To understand the difference between both infection and colonisation and pathogenic and non pathogenic organisms‚ the areas of infection and the types caused by different organisms. In addition‚ the learner will understand the methods of transmission‚ the conditions needed for organisms to grow‚ the ways infection enter the body and
