Which type of bacteria is characterized by small round balls that are very spread out?

Moraxella is characterized by its coccobacillary shape, where the bacteria appear as small round or oval cells that can often be found in pairs or short chains. This morphology, combined with their tendency to be well-dispersed, gives them a distinct appearance under the microscope.

The choice of Moraxella as the correct answer is supported by its description as having a somewhat irregular, spread-out arrangement compared to other bacterial genera. Neisseria, while also cocci, typically appears in pairs (diplococci) and often exhibits a more closely clustered arrangement. Enterococcus, which is also spherical, can appear in pairs or chains but tends to be somewhat more organized than what is described. Clostridium, on the other hand, is rod-shaped (bacillary) and does not fit with the description of being small round balls at all. Thus, Moraxella's unique spherical shape combined with its spread-out arrangement makes it the best fit for this question.
