Select and explain.

Expression of methicillin resistance in Staphylococcus aureus increases when it is incubated at 37degC on blood agar, D. Methicillin resistance in Staph. aureus is independent of b-Lactamase production
C: Expression of methicillin resistance in Staphylococcus aureus increases when it is incubated at 37degC on blood agar
Answer: C: Expression of methicillin resistance in Staphylococcus aureus increases when it is incubated at 37degC on blood agar 
Explanation: Ans. (c) Expression of methicillin resistance in Staphylococcus aureus increases when it is incubated at 37degC on blood agar "Methicillin resistance is expressed more when Staph. is incubated at 30degC than at 37degC." Refer Ans. No. 3 for full explanation
