Diplococci
|
Paired bacteria

Streptococci
|
Chain of bacteria

Staphylococci

Cluster of bacteria
|
|
Coccobacilli
|
A bacterial cell intermediate in morphology between a coccus and a bacillus. While still rod shaped, they are so short and wide that they resemble cocci
|
|
Bacillus
|
Rod-shaped bacteria
|
|
Spirilla
|
Spiral-shaped bacteria
|
|
L-form
|
Bacteria that lose normal shape due to adverse environmental conditions; once normal conditions are reestablished cells revert to normal shape
|
|
Motility
|
Ability of a microbe to move by itself
|
|
Flagella
|
Long thin structure attached to the outside of the cell; uses whipping motion to provide motility to the cell
|
|
Cilia
|
Fine, short, hairlike extensions located on the surface of the cell; their coordinated, rhythmic movement allows the cell to move
|
|
Examples of bacterial nutritional needs
|
Carbon, oxygen, sulfur, nitrogen, hydrogen, phosphorus, vitamins, iron, calcium, copper, zinc
|
|
Obligate aerobes
|
Require level of oxygen found in a typical room
|
|
Microaerophiles
|
Require oxygen but at level lower than that found in room air; (about 5% oxygen)
|
|
Obligate anaerobes
|
Will not grow if there is any amount of oxygen present in the environment
