Fungi These are living organisms with many cells with a nucleus also known as Eukaryotes. Person-to-person transmission is the major route of colonization within health care facilities.
The cells of the mucous membranes, such as those lining the respiratory passages that we breathe through, are particularly open to virus attacks because they are not covered by protective skin.
Its normally found as a single cell.
List of pathogens and diseases they cause
It is due to external invasion of pathogenic or disease-causing microorganisms. E a human body. Fungi live in the air, water, filth and on plants and they lot live in the body, usually without do illness. Localised infection: Localised infection means the infection stays in one place. When a virus enters the body, it enters some original cells and takes over making the now host cell steel the split the virus needs to reproduce, the cells atomic number 18 in conclusion washed-up through this process. They can't multiply on their own, only inside the cells of other organisms. Fungi Valley fever, athlete's foot, ringworm, yeast infection D. Fungi Mould, yeast and mushrooms ar all types of Fungi. Identify common sources of infection - people.
Through this exchange between parasite and host they will usually weaken their host but not kill them. Explain what is meant by "systemic infection" and "localised infection" A systemic infection is one that affects the whole body, probably travelling in lymph or blood.
They are capable of latching onto cells and getting inside them. A mould which causes infections in humans is Trichophtyion rubrum which is one cause of ringworm and it may also infect nails. Viruses are small too small to be seen under a light microscopeand infectious, they can only replicate inside of living cells of organisms like bacteria, fungi, animals and plants.
Fungi and parasites
D: Parasites: Are organisms such as fungi or worms that live in or on a host to obtain nourishment without providing any benefit to the host. Fungi live in the air, water, filth and on plants and they commode live in the body, normally without do illness. Not following these procedures, or observing good hygiene practices washing hands after visiting the bathroom, care when preparing food, etc , will lead to the spread of infection. The infectious agent may remain localized or may enter the blood stream. Like protozoa they can be either free-living or parasitic Food, drink or other infected products can be swallowed and infect the stomach or bowels. Parasites A parasite is a tiny organism that lives in or on a host A body which they use in order to feed. It reproduces sexually as well as asexually.
Parasites can cause severe illnesss, there are 3 main types of parasites: protozoa, helminths, and ectoparasites. Protozoa- They are single celled organisms that can be nonsymbiotic or bloodsucking in nature.
