The cells in the micrograph show the typical morphology of Bacillus, which are rod-shaped with a characteristic "bamboo-like" appearance. Enterococcus and Staphylococcus are cocci-shaped and do not match the morphology seen in the image. Leptospira are spiral-shaped bacteria and Actinomyces are branching, filamentous bacteria, neither of which match the morphology seen in the image.
