third generation cephalosporin

third generation cephalosporin

Infectious disease A group of broad-spectrum antibiotics–eg, cefatoxime, ceftazidime, ceftriaxone and moxalactam that are structurally related to penicillins and used against penicillinase-producing bacteria; TGCs are more active against enteric bacteria, are stable against the β-lactamases of H influenzae and N gonorrhoeae, have a longer serum T1/2 than 1st generation cephalosporins– administered twice/day, cross the blood-brain barrier and effective against gram-negative CNS infections

Conclusions: Third generation Cephalosporin resistance is present in 16.2% of patients with community acquired spontaneous bacterial peritonitis.
Furthermore, uncontrolled use of aztreonam and cephalosporin (Third generation cephalosporin) results in the mutation in the enzymes and which in turn cause the emerge of ESBL producing pathogens (Grover et al., 2006; Sharma et al., 2013; Kumar et al., 2014).
A systematic review of the literature showed that tazobactam and clavulanic acid are partial inhibitors of KPCs and the hydrolysis of the third generation cephalosporin is relatively weak in KPCs [5].
We report a case of typhoid due to Salmonella enteric serovar Typhi which was resistant to all the first line antibiotics as well as fluoroquinolones and third generation cephalosporin. Hence the patient had to be treated with meropenem, a carbapenem drug which is not usually recommended for the treatment of typhoid fever.

In our study, resistance to third generation cephalosporin's was found to coexist with resistance to two or more antibiotics like ampicillin, nalidixic acid, cotrimoxazole, nitrofurantoin, norfloxacin, amikacin as also reported by Subha et al (18) and Duttaroy et al (19) indicating multidrug resistance pattern.
