Microbiology:

Science that deals with microorganisms .

Vocabulary Words

Outbreak-occurrence of a disease greater than would otherwise be expected at a particular time .

Important Information

Virus:

*non-living organisms

*needs a host to reproduce

*disease producing particles

*to prevent viruses we get vaccines

*invades healthy cells and reproduce

*the cells invade and kill other cells


Parasite:

*lives on/inside another organism

*takes nutrients from its host


Bacteria:

*singular-celled

*reproduce rapidly

*are everywhere

*are prokaryotic

*treated with antibiotics


Fungi:

*decomposes the organic matter

Outbreak

Occurrence of a disease greater than would otherwise be expected at a particular time .

Epidemic
