coccus
pl. cocci [L.] a spherical bacterium, usually slightly less than 1 μm in diameter, belonging to the Micrococcaceae family. It is one of the three basic forms of bacteria, the other two being bacillus (rod-shaped) and spirillum (spiral-shaped). Almost all of the pathogenic cocci are either staphylococci, which occur in clusters, or streptococci, which occur in short or long chains. Both staphylococci and streptococci are gram-positive and do not form spores.
