Final answer:
Looking at bacteria under a microscope can provide important information about their morphology and arrangement. In the case of pus in blemishes, the technician identified Staphylococcus aureus, a common cause of wound infections. This knowledge helps determine appropriate treatment options.
Step-by-step explanation:
By looking at bacteria under a microscope, we can learn important information about their morphology and arrangement. In the case of bacteria found in the pus of blemishes, the technician identified spherical, gram-positive bacteria that form grape-like clusters characteristic of staphylococcal bacteria. Further testing revealed that the bacteria are Staphylococcus aureus, which is a medically important species and a common cause of wound infections. Understanding the specific type of bacteria present in the pus helps determine appropriate treatment options, as some strains of S. aureus are resistant to many antibiotics.
