Infection – is an invasion to body tissues from a disease- caused microorganism. Colonisation – is multiplication of microorganisms without tissue invasion or damage. 2.4 Explain what is meant by “systemic infection and localized infection” Systemic – is when infection is distributed throughout the whole body. Localized – is when infection

Through processes know as wet mounts and simple stains‚ observing living microorganisms through a compound microscope can generate a clearer understanding of their appearances and movements. Microorganisms are living things that for the most part cannot be seen through the naked eye. They live on and among humans‚ as well as plants‚ animals‚ and all that is a part of the Earth. Harmless as most seem to be to humans‚ microorganisms are an important relevance of study for human interest in varied perplexities

Definition STERILIZATION The process of freeing an article from microorganisms including their spores. By definition‚ it effects a reduction in the number of microorganisms (more than 99.9999% are killed).

1.1 & 1.2 To start this unit I will be discussing about the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria: These are tiny microorganisms‚ they cannot be seen with the naked eye. They exist on virtually every living thing or object in the environment i.e. dirt‚ water‚ caves‚ trees‚ dead animals‚ and within everybody living on earth. Its nutrition is from its surroundings. We carry bacteria in the body‚ mainly in the intestines‚ on the genitalia or on the skin. Bacteria can

and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms or even destroyed them‚ as they have antimicrobial agents. Some examples of condiments and preservatives

The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I analyzed the Starch plate and was able to determine that
