Shapes and arrangement of microorganisms
Bacillus
The microorganism which is rod shaped is known as bacillus (plural- bacilli).
Depending on different arrangements of bacilli they are known as…
Monobacillus
Just like mono coccus they do remain unattached with other microorganisms and exist as single.
Coccobacillus
Compared to other bacilli, Coccibacilli are shorter in length and thus appear stumpy.
Diplobacilli
Like Diplococci, Diplobacilli occur in pairs.
Streptobacilli
Streptobacilli occur as elongated chains.
Palisades
Bacilli attaches at angles and makes a picket fence-like structure.
Ameboid The microorganism which does not have a definite shape and keeps on changing its shape is known as ameboid.eg. Amoeba
Coccus
The microorganism which is spherical or oval in shape is known as coccus (plural- cocci).
Depending on different arrangements of cocci they are known as…
Mono coccus
They do remain unattached with other microorganisms and exist as single.
Diplococci
Diplococci are the type of cocci that occur as a pair (two joined cells).
Tetrad
Tetrad are arranged in groups of four cells. Following division, the cells remain attached and grow in this attachment.
Sarcina
Sarcina occurs in groups of 8 cells. They form cube-like structures.
Streptococci
Streptococci are a type of bacteria that arrange in a chain form (resembling chains).
Staphylococci
Staphylococci are a type of bacteria that form grape-like clusters.
Spiral
Some types of microorganisms found in curved shape when viewed under the microscope. However, these curves vary in shape making it possible to differentiate them from each other.
Vibrio
Generally, vibrio are comma-shaped and thus not fully twisted (curved rods).
Spirillum
Spirilla possesses a helical shape. However, they are more rigid, thick with the typical flagella.
Spirochete
Spirochetes are characterized by more helix than spirillum. Spirochetes are flexible and thin.
