A basic knowledge of microbiology is important in preventing the spread of disease through proper disinfection within the salon.BACTERIAMinute, one-celled vegetable microorganisms found nearly everywhere. Also known as germs or microbes.:::Prominent in dust, dirt, refuse, and diseased tissues.They can exist almost anywhere and can only be seen through a microscope.

BacteriaChapter 2.1Salon EcologyMicrobiologyGenerally classified as two types:NonpathogenicPathogenicBacteria that do not produce diseaseBacteria that do produce diseaseBacteriaNonpathogenicPathogenicHarmlessCan be beneficialMany live on surface of skin Saprophytes live on dead matter70% of all bacteriaCause infection and diseaseDistinct shapesSome produce toxinsSpread easilyLive everywhereChapter 2.1Salon EcologyMicrobiologySaprophytes live on dead matterNon pathogenic

Just to help you rememberSaprophytes are bacteria that have the sap knocked right out of them, so weak they cannot produce disease. There is no fight left in them

Round-shaped that appear singly or in the following groups.

All the letters but i are rounded or circular. Cocci starts with a "c", as does circular..

StaphylococciPus-forming bacteria that grow in clusters like grapes;

cause abscesses, pustules, and boils

Staphylococci form a bunch (like grapes) and "boil" up trouble by causing boils. the "staff" form a "bunch" and "boil" up trouble.

Streptococci.Pus-forming bacteria arranged in curved lines resembling a string of beads; Cause infections such as strep through and blood poisoning

DiplococciSpherical bacteria that grow in pairs and cause diseases such as pneumonia

The word diplococci includes "diplo" which means two.draw 2 circles side by side and then draw them coughing.

Bacilli Short rod-shaped bacteriaThey are the most common and produce diseases such as tetanus, typhoid, tuberculosis, and diphtheria.

rod shaped and cause fevers, so the term "hot rod" Hot Rod

SpirillaSpiral or corkscrew-shaped bacteria.

They are subdivided into subgroups: which causes syphilis (an STD) or lime disease.

corkscrew in shape, like a slinky or spiral c

MitosisThey then divide into two new cells. The division is called mitosis Daughter Cells the new cells are called daughter cells.

Movement of BacteriaChapter 2.1Salon EcologyMicrobiologyGrowth of Bacteria

Bacilli and spirilla use flagella (cilia) to propel themselves(Bacilli and Spirilla) flagella or cilia Motile and use slender, hairlike extensions known as flagella or cilia For locomotion A whip like motion of these hairs moves the bacteria in liquid.
