Students have asked these similar questions
Some antibiotics fail to kill/inhibit a pathogen simply because the microbe is naturally (intrinsically) resistant to it.
True or False ?
1) What is NDM-1? How can NDM-1 spread to different types of bacteria?
2) Why are Gram negative bacteria so much harder to treat with antibiotics?
3) What is KPC? Where does it live?
List all the antibiotics in the above table that work through destroying the bacterial cell wall. (if there
are none listed please state that)
