High-level resistance to beta-lactam antibiotics in Streptococcus pneumoniae is mediated by successive alterations in essential penicillin-binding proteins (PBPs). In the present work, single amino acid changes in S. pneumoniae PBP 2x and PBP 2b that result in reduced affinity for the antibiotic and that confer first-level beta-lactam resistance are defined. Point mutations in the PBP genes wer...

OBJECTIVE To evaluate the clinical usefulness of piperacillin (4 g/day) therapy for community-acquired pneumonia compared to sulbactam/ampicillin (6 g/day). METHODS A randomized prospective clinical study was conducted in patients with mild to severe community-acquired bacterial pneumonia. RESULTS The overall clinical efficiency of piperacillin therapy (4 g/day) in these patients (41/53=77....
This comparison of intermittent versus extended-infusion piperacillin-tazobactam among patients with Gram-negative infections revealed similar mortality and length of stay. Outcomes remained similar when stratified by MIC value.

 Purpose: To study the pharmacokinetics of piperacillin/tazobactam in renal replacement therapy (CRRT) patients with chronic failure (CRF).
 Methods: Six CRF treated CRRT First Affiliated Hospital Hebei North University from April 2020 to July were selected and administered 4 g piperacillin 0.5 tazobactam within 30 min after, at 5, 30, 45, 60, 90, 120, 180, 240, 360 480 after CRRT. T...
Piperacillin metabolism and biliary excretion are different between humans and preclinical species. In the present study, piperacillin metabolites were characterized in bile and urine of healthy humans and compared with metabolites formed in vitro. Volunteers were administered 2 g of piperacillin IV; blood, urine, and duodenal aspirates (obtained via a custom-made oroenteric catheter) were coll...
