Which of the following are true about main and secondary memory?

Alteration in PBP: Modification of the PBP is a favored mechanism of resistance to Gram-positive bacteria, whereas production of -lactamases is a mechanism for the development of resistance to Gram-negative bacteria. The presence of mutation in penicillin-binding protein leads to a reduced affinity to -lactam antibiotics. The resistance ofEnterococcus faeciumto ampicillin andStreptococcus pneumoniaeto penicillin is by this mechanism. Similarly, inStaphylococcus aureus, the resistance to methicillin and oxacillin is associated with integration of a mobile genetic element - "staphylococcal cassette chromosome mec" - into the chromosome ofS.aureusthat contains resistance gene mec A.[4,15,16] mec A gene encodes PBP2a protein, a new penicillin-binding protein, that is required to change a native staphylococcal PBP. PBP2a shows a high resistance to -lactam antibiotics.S. aureusstrains resistant to methicillin can be cross resistant to all -lactam antibiotics, streptomycin, and tetracycline and in some cases to erythromycin
