Beta-lactam/beta-lactamase inhibitor combinations (BLBLIs) are among the most controversial classes of antibiotic agents available for the treatment of infections caused by extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria (ESBL-GNR). Piperacillin-tazobactam (PTZ) is one of the most frequently utilized antibiotic agents for empiric gram-negative bacterial coverage and remains active against a large proportion of ESBL-GNR. Furthermore, good antimicrobial stewardship practices encourage the use of carbapenem-sparing treatment regimens for infections due to ESBL-GNR...

Relebactam (formerly known as MK-7655) is a non-β-lactam, bicyclic diazabicyclooctane, β-lactamase inhibitor that is structurally related to avibactam, differing by the addition of a piperidine ring to the 2-position carbonyl group. Vaborbactam (formerly known as RPX7009) is a non-β-lactam, cyclic, boronic acid-based, β-lactamase inhibitor. The structure of vaborbactam is unlike any other currently marketed β-lactamase inhibitor. Both inhibitors display activity against Ambler class A [including extended-spectrum β-lactamases (ESBLs), Klebsiella pneumoniae carbapenemases (KPCs)] and class C β-lactamases (AmpC)...

BACKGROUND: Vancomycin is very commonly used in combination with piperacillin-tazobactam (PTZ) as an initial empiric therapy for moderate to severe infections, whenever coverage for both methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa is required. The combination of vancomycin and PTZ in adults has recently been reported to significantly increase the risk of developing acute kidney injury (AKI) relative to vancomycin monotherapy; such reports in pediatrics are sparse...

The efficacy of empirical non-carbapenem antibiotics for extended-spectrum beta-lactamase-producing Enterobacteriaceae bacteremia (ESBL-B) is still inconclusive. We conducted a multicenter retrospective cohort study to evaluate the efficacy of empirical non-carbapenem antibiotics for treating ESBL-B. Electronic medical records of individuals who were diagnosed with ESBL-B were reviewed between January 2010 and December 2014 at four university hospitals in Korea. Patients were classified into non-carbapenem and carbapenem groups according to the empirical antibiotic regimen...

Difficulties in distinguishing species of the Elizabethkingia genus by MALDI-TOF prompted use of rpoB sequencing to investigate species distribution among 44 isolates from cystic fibrosis (CF) patients. Forty-three isolates from 38 patients formed a cluster comprising E. miricola and proposed novel species E. bruuniana sp. nov., the exception clustering with proposed species E. ursingii sp. nov., also part of this wider cluster. All 44 isolates were PCR-positive for urease gene ureG, whereas only one of 23 E...
