Infectious disease

By David.Rubio


Microbiology is the study for microscopic organisms such as bacteria viruses and archaea fungi and protozoa. This discipline includes fundamental research on the biochemistry physiology, cell biology, ecology ,evaluation and clinical aspects of microorganisms including the host response to these agents


A non living pathogen that can change mutate.It unfects a host cell and replicate its self while also destroying the cell in the process also causes illness and disease

Bacteria is a single celled prokaryotes that can cause disease. Multiply its self and rapidly and can form colonies

Outbreak: is an occurrence of a disease grater than otherwise would be expected at a particular time and place

Epidemic: is an outbreak of a disease that affects a small population/a small area of a specific country or regin

Pandemic: is an epidemic that spreads over a very large area or even the'y entire world


Vector:An organism typically an insect that transmits disease

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

Protozoa:Diverse organism that cannot be classified as animals plants or fungi

Virus:A non living pathogen that can change mutate.It infects a host cell and replicates ts self to cause illness and disease

Bacteria:Single celled proloaryotes that can cause disease.Multiply rapidly and can form colonies

Parasite:An organism that lives in or an another organism called a host cell taking nutrients and often harming it in the process

Fungi:A single celled or multi cellular organism that can decompose or absorb organic matter

Host cell:A cell that a virus invades/takes over and makes copy's of it self

Quarantine:A time or place of isolation in which people or animals that have been exposed or contagions diseases are placed
