All are true except: (DNB Dec 2011)
|A||Cefoperazone is antipseudomonas|
|B||Cefoxitin has no anti anaerobic activity|
|C||Ceftazidime is Group III cephalosporin|
|D||Cephalosporin act by inhibiting cell wall synthesis|
Ref.: - KDT, 6th, Katzung, 9th.
This is answer by exclusion. Cephalosporin; similar to penicillins act by inhibiting the cell wall synthesis. Ceftazidime is III generation cephalosporin which has strong anti-pseudomonal activity similar to cefoperazone.
One of the important feature of II generation compounds – some drugs like cefoxitin are having activity against the anaerobes like B. fragilis. Thus this statement is false.
