Medical Significance
- Some strains of staphylococcus, particularly Staphylococcus aureus, can cause severe illnesses like pneumonia, skin infections, and food poisoning.
- Methicillin-resistant Staphylococcus aureus (MRSA) is a well-known strain that is resistant to many antibiotics, making it a serious health concern in hospitals.
- Staphylococci are part of normal skin flora, meaning they usually live harmlessly on our skin, but can cause issues if they enter the body through cuts.
