What is microbiology?

Microbiology is the study of microorganisms, such as bacteria, viruses and fungi.Those microorganisms can only be seen under a microscope that is how small they are, despite there size the have a huge impact on us humans.

Virus

A virus is non-living pathogen that can change or mutate. But a virus can not survive all on its owe it needs a host cell to reproduce, once it finds a host cell it can cause an illness or disease. A virus can be transmitted by air, and surfaces & are treated by vaccines. A good way to prevent a virus is to wash hands with soap and water. Some illnesses a virus can cause as HIV.

Bacteria

Bacteria is a single-celled prokaryotes that can cause disease. They multiply rapidly and can form colonies. Bacteria is living and is transmitted by direct and indirect contact such as surfaces, people, and air. Bacteria can be treated with antibiotics and can be prevented by properly cleaning yourself and washing hands with soap and water. Some of the diseases bacteria can cause are food poisoning, salmonella, rabies, lyme disease, bacterial meningitis, and leporsy . Bacteria reproduces by binary fission and can live in water.

Fungi

Fungi is living and is a single celled or multi cellular organism that can decompose and absorb organic matter. Fungi can be transmitted by wind, water, animals, and spores. Some ways to treat fungi is to use anti-fungal creams, shampoos, and medicine. Some common fungi infections are athletes foot, jock itch, and candida.

Parasites

A parasite is a living organism that lives on or in anther organism that is called a host and often harming in the process.parasites move on their own from one organism to the next to the next and can be treated with medicine or direct removal form host. One of the diseases parasites can cause is maleria.

What is?

Pandemic- A pandemic is a wide spread disease across the whole world


Outbreak- Occurance or a disease greater than would otherwise be expected at a particular time and place


Epidemic- An out break of a disease tha affect many people in a specific country or region.

Similarity's and differences

One similarity between pandemic and epidemic is that the both are occur when there is an outbreak of a disease . A difference is that one consist of a country or region and the other of a very large area.

Vocabulary

Vector-An organism typically an insect that transmits a disease.


Pathogen-A virus, bacteria, fungi, parasite, or protozoa that can cause illness and infection


Protozoa- Diverse organisms that cannot be classified as animals, plants, or fungi. Ex: amoebas , and algae.


Host cell-A cell that a virus invades ,takes over, and makes copies of itself.


Quarantine- Time or place of isolation in which people or animals have been exposed to infections or contagious diseases are placed.
