Cocci bacteria are rarely motile.
Coccus or cocci bacteria are round or sphere-shaped bacteria. They lack flagella or any locomotive organ so they are non-motile.
Cocci contain multiple genera like Streptococcus, Staphylococcus, Enterococcus and Diplococcus. They are divided based on the pattern they grow. For instance, Diplococcus always appears as joined two cells implying a pair of cells.
They can also be both gram-positive bacteria (eg. Neisseria spp.) and gram-negative bacteria (eg. Streptococcus spp.).
They can show pathogenicity, symbiotic and commensalism. Some of the pathogenic cocci bacteria are Streptococcus, Staphylococcus and Pneumococcus which can cause throat infection, food poisoning and pneumonia respectively.
