NEET PG Medical – 2018 – Question – 70
Anaerobes are resistant intrinsically against –
a) Beta lactam antibiotics
b) Aminoglycosides
c) Azithromycin
d) Metronidazole
Show Answer
Correct Answer – B
Answer: B – Aminoglycosides
Anaerobic bacteria particularly are resistant to aminoglycosides due to lack of oxidative mechanism to drive drug up-taking process.
Intrinsic resistance / Insensitivity:
- Innate ability of bacteria to resist activity of particular antimicrobial agent
- Inherent structural or functional characteristics allows for tolerance of a particular drug or antimicrobial class. i.e., Susceptibility to that particular drug is reduced.
