Final answer:
Staphylococcus aureus clusters appear as grape-like clusters of cells.
Step-by-step explanation:
Staphylococcus aureus Clusters
Clusters of S. aureus cells appear as grape-like clusters. This characteristic arrangement can be observed under a scanning electron microscope. The cells are spherical in shape and typically form tight clusters resembling grapes.
Example:
Figure 4.22 shows a scanning electron micrograph of S. aureus cells, illustrating the typical grape-like clustering pattern.
