Considerable variation is seen in the actual shapes of bacteria, and cells can be stretched or compressed in one dimension. Diplococci: Cocci that remain in pairs after dividing. Corrections? In every human population on every part of the earth there is streptococcus bacteria that produces just about the exact same reaction in all humans. Multiple chains of the bacteria are generally called streptococci, and many bacteria that take on this shape are found in the genus Streptococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus. Coccus (noun) A form of bacteria, shaped like a globule.

Cocci bacteria are bacteria that are spherical or oval in shape. Any bacterium, which has either a spherical, ovoid or round-shaped is a coccus. Bacterial Shape. vibrios. For example, diplococci are cocci in pairs, streptococci are chains, and staphylococci are clusters of multiple cocci. It is assumed that coccoid forms were derived from rod-shaped organisms through evolutionary time. Cocci is basically spherical-shaped and bacilli is rod-shaped. Coccus refers to the shape of the bacteria, and can contain multiple genera, such as staphylococci or streptococci.
