Unit 265 Causes and spread of infection. Outcome 1 Understand the causes of infection 1. Identify the difference between bacteria‚ viruses‚ fungi and parasites? The difference between bacteria‚ viruses‚ fungi and parasites is: Bacteria Bacteria is a single celled organism‚ bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body‚ only 1% of bacteria is actually harmful. It ’s bad or infectious bacteria that cause illness

Monica Franco Biology 1A Lab Erik Arevalo Parvovirus Parvovirus is one of the smallest eukaryotic viruses that exist. It is a disease that attacks an organism’s cells and can go into the bloodstream‚ allowing other types of illnesses such as subclinical infections‚ dermatologic‚ hematologic‚ and rheumatologic manifestations to attack the body (Cotmore et al.‚ 2013). A key characteristic of parvovirus is that it replicates itself rapidly through an organism’s cells. It is a part of the parvoviridae

Most types of Escherichia coli are harmless and are actually a part of a healthy human intestinal tract but some are pathogenic. It can be transmitted multiple ways; fecal-oral route‚ fecal contamination of water‚ food or fomites‚ poor sanitation and hygiene (General Microbiology Fact Sheet). A person can show signs and symptoms of Escherichia coli which include fever‚ bloody diarrhea‚ may result in hypotension with severe toxemia. The incubation period is 12-72 hours. Knowing

Microbiology‚ Test 3 Study Guide Chapters 14‚ 15‚ 16 and 17 Chapter 14 This chapter is about the principles of disease and epidemiology. Epidemiology – the science that studies when and where diseases occur and how they are transmitted. CDC‚ Atlanta‚ tracks and traces diseases. ONE World (the idea that it’s all in one place‚ it could happen anywhere; locally‚ states‚ large counties track the incidences and occurrences of disease)

1.1 and 1.2 Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two‚ which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless‚ but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis‚ pneumonia‚ salmonella

Hand hygiene has been stated as the one main element that can prevent the spread of MRSA (Gould 2002). Washing hands is not kid’s stuff – not in the era of MRSA. Once entrenched MRSA can be extremely difficult to treat. If it gets into the blood stream it can be lethal (Belkum‚ Verbrugh 2001). Simor and Andrew (2001) also emphasise that hand washing is the most important control practice. It is essential because personal contact is the primary mode of MRSA transmission. Therefore good hand washing
