Which Group of Bacteria Demonstrate the Highest Intrinsic Antibiotic Resistance

Question

​Which group of bacteria demonstrate the highest intrinsic antibiotic resistance to vancomycin?
A)​Enterococci
B)Group A streptococci
C)​Group B streptococci
D)​Viridans group streptococci

Accepted Answer

Enterococci demonstrate the highest intrinsic resistance to vancomycin due to their thick cell wall and ability to modify peptidoglycan precursors, reducing vancomycin's effect on the cell wall. This resistance can be further enhanced through acquisition of additional resistance mechanisms such as vancomycin resistance genes.
