Final answer:
The correct fill in the blank answers for the provided question are (c) Penicillin, cephalosporins for the first part and (d) All of the above for the second part, highlighting why MRSA is a significant concern for medical professionals due to its antibiotic resistance, which can lead to serious untreatable infections.
Step-by-step explanation:
Staphylococcus aureus has a significant resistance to multiple antibiotics, posing a serious challenge to healthcare providers.
One of the well-known resistant forms of S. aureus is Methicillin-resistant Staphylococcus aureus (MRSA), which is resistant to all β-lactams, including methicillin, amoxicillin, penicillin, and oxacillin.
For the question provided, the correct answer is: (c) Penicillin, cephalosporins, as MRSA is typically resistant to these antibiotics.
MRSA has become a concern due to its ability to cause serious infections and resist most antibiotics available for treatment.
The emergence of MRSA as a serious infectious disease requires prompt and effective treatment strategies to manage and prevent widespread infections, especially in community and healthcare settings.
The medical community is highly concerned with MRSA because of its potential to: (d) All of the above, which includes the potential transfer of resistance to other bacteria, the critical timing of correct antibiotic treatment, and the potential evolution into a 'super bug' with additional resistance genes acquired from other bacteria.
