Infections
WORDS TO KEEP IN MIND
Pathogen - diseases caused by bacteria, virus, and other microorganisms
Susceptible - lacking the ability to resist something
Host - An organism that keeps another organism, so they live together, inside and thier thier body
Disease - a condition of an organism which intervene the normal bodily functions that can lead to pain, weakness, and other symptoms
Bacteria - single-celled microorganisms that are everywhere around us
Virus - tiny parasite (organism that gets nourishment and shelter from another organism) that can only reproduce if it is within a living being or anything that corrupts something else
Reservoir - Infectious agent normally lives and multiplies
Mode of transmission - how pathogens get from a reservoir to a susceptible host
White blood cells - colorless cell that moves within the blood and body fluids and is involved in fighting against foreign substances and diseases
Antibodies - a blood protein made in order to respond and go against a specific antigen(foreign substance) it connects chemically with substances that shouldn't be in your body (bacteria and viruses)
Portal of entry - where microorganisms enter the body to cause disease/infection (mucous, skin, coughing, sneezing)
Portal of exit - where microorganisms exit the body to enter another host to cause more disease and infections
VIRUS & BACTERIA
VIRUS
Needs a host
Does not grow, feed, or excrete
Genetic material and protective coating
100x smaller than bacteria
Simpler DNA
Multiplying fast
BACTERIA​
Self reproducing
Gros, feeds, and excrete
Contains cytoplasm, call wall, and nucleous
Larger than virus
No complex DNA
Multiply slower
Single cell makes a copy and splits into two identical cells
The chain of infections
The chain of infections is made up of six different parts: pathogen, reservoir, portal of exit, means of transmission, portal of entry, and the new host. Each part has a different role in the chain.The pathogen has to directly or indirctly find a way of transmission and a portal of entry. Some portals of entry are the digestive, circulatory, and respiratory system. Once the pathogen is in the portals of entry it will began to attack the cells in your body. Mean while your body will fight back the bacteria or virus. The portal of exit will allow the pathogen to spread to a new host through feces, mucous, salvia, urine, and other ways.
What does it mean if it is broken? It means that you are at risk of getting a disease. Some ways we can prevent it from being broken is getting the vaccines you need and using antibiotics. Other things we can do on our own is cleaning your hands, covering coughs and sneezes and staying home when sick. A way we can prevent bacteria and virus from spreading in our homes is cleaning and disinfecting were you live.
