Treatment options for extended-spectrum β-lactamase-producing Enterobacteriaceae are limited. Piperacillin-tazobactam and cefepime represent potential alternative treatment options; however, large prospective studies are lacking. This review evaluates the current literature regarding use of piperacillin-tazobactam and cefepime for the treatment of extended-spectrum β-lactamase-producing Enterob...

Agar dilution MIC methodology was used to compare the activity of sulopenem with those of amoxicillin/clavulanate, ampicillin/sulbactam, piperacillin-tazobactam, imipenem, clindamycin, and metronidazole against 431 anaerobes. Overall, MIC(50)/(90) values were as follows: sulopenem, 0.25/1.0 microg/ml; amoxicillin/clavulanate, 0.5/2.0 microg/ml; ampicillin/sulbactam, 0.5/4.0 microg/ml; piperacil...

}iperacillin/tazobactam (ZOSYN, Lederle Laboratories, Pearl River, NY) is the most recently approved combination of a [3-1actam antimicrobial agent with an inhibitor of bacterial [3-1actamases. In vitro and clinical studies have demonstrated efficacy in polymicrobial infections such as obstetric, gynecologic, and soft-tissue infections. Piperacillin/ tazobactam appears to be an appropriate drug...

Although drug fever may develop after administration of the drug by various routes, it has not been reported with antibiotic-loaded bone cement. Here, a case of drug fever induced by piperacillin/tazobactam loaded into bone cement is reported. A 72-yr-old woman presented with fever that developed two weeks after insertion of bone cement loaded with antibiotics including piperacillin/tazobactam ...

BACKGROUND Neonatal bilateral endogenous endophthalmitis is rare and often results in devastating visual outcome. FINDINGS An 18-day-old neonate presented with whitening of the cornea in the left eye. The child was examined under anesthesia, and a diagnosis of bilateral endogenous endophthalmitis was made. Vitreous biopsy from the left eye showed no growth. Blood samples showed growth of Stap...

The in vitro activities of a new quinolone, WIN 57273, and the combination of piperacillin and tazobactam, a beta-lactamase inhibitor, were compared with those of cefoxitin, ceftizoxime, chloramphenicol, clindamycin, imipenem, metronidazole, and piperacillin for 123 clinical anaerobic isolates. Ceftizoxime and cefoxitin had equivalent activities, while metronidazole was active against gram-nega...
