Coccoid - Wikipedia
Coccoid means shaped like or resembling a coccus, that is, spherical. The noun coccoid or coccoids may refer to: a level of organization, characterized by unicellular, non-flagellated, non-amoeboid organisms, with a definite shape, in general but not always ovoid. It is found in many groups, e.g.: some bacteria, also called cocci (pl. of coccus)
Bacterial cellular morphologies - Wikipedia
Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped (bacillus). But, there are also other morphologies such as helically twisted cylinders (example Spirochetes), cylinders curved in one plane (selenomonads) and unusual morphologies (the square, flat box-shaped cells of the Archaean genus Haloquadratum).

Colonial coccoid cyanobacteria form colonies of cells held together by mucilage (slimy, viscous material produced by the cells). Colony shapes include spherical, sheet-like, and irregular, among other forms.
How to get (a)round: mechanisms controlling growth and
In this Review, we discuss recent progress that has advanced our knowledge of the complex mechanisms for chromosome segregation and cell division in bacteria which have, deceptively, the simplest possible shape: the cocci. Bacteria come in a range of shapes, including round, rod-shaped, curved and spiral cells.
