Disease: Refers to when your body is put out of homeostasis; it interferes with how we function or, in other words puts out body into dis-ease.
Acute disease: A disease that lasts for a short period of time Chronic disease: a disease that lasts for a long period of time. Sign: A sign is something that can visually be seen by either the infected person or a friend or family member of said person Symptom: A symptom refers to how a person generally feels due to a disease Vectors: Are ‘Things’ (organisms or cells) that can pass on infections disease without feeling the effects of said disease. In tact skin: Intact skin refers to skin that has no holes in it and it therefore impermeable to foreign pathogen. the word 'intact' is very important. Unicellular: Organisms that are made up of only one cell Optimal environments: Environments that are within the tolerable range of an organism. Non-optimal environments: Environments that are outside of the tolerable range of an organism (i.e too acidic or too hot) Protists/Protozoa: Unicellular, eukaryotic organisms that that are heteretrophic and reproduce both sexually and asexually. Arthropods: Parasites that live on the outer surface of an organism. |
Cellular: Cellular refers to organisms that are living organisms that have every characteristic of a cell.
Non-cellular: Non-cellular refers to organisms that do not have the required characteristics of being a cell ‘Normal Virus’: Are viruses that DNA-->RNA-->Protein Retrovirus: Are viruses that RNA-->DNA-->RNA-->Protein. Prion: prions are proteins that have no genetic materials and infect other cells causing them to lyse. Any other protein it binds to also becomes infected. They are made from proteins that, for some reason, have malfunctioned. Parasitic: organisms that is living inside/on the surface of a host that obtains the host’s nutrients; with no benefit to the host. Worms: Are cellular, parasitic organisms that benefits from the host by either living inside or on the surface of another organism; feeding off the said organism. Viroids: non-cellular and do not produce proteins and therefore don’t contain proteins. They are made up of only RNA. There are no viroids known to infect animals Fungi: Eukaryotic organisms that can produce spores and contain enzymes that are able to break down and dissolve organic matter. Spores: Spores are like the ‘babies’ of fungi and increase the virulence and survivability of the pathogen. Spores are formed by fungi and are able to store the genetic material of fungi. |
