REVIEW
Young R Lee, Nathaniel T Baker
Meropenem-vaborbactam is a carbapenem and β-lactamase inhibitor combination that is newly indicated for the treatment of complicated urinary tract infections (cUTI), including adult pyelonephritis. Vaborbactam was developed due to emergence of carbapenem-resistant strains of Enterobacteriaceae. In a phase I trial, patients that received meropenem-vaborbactam 2-2 g intravenously over 3 h every 8 h, Cmax was 58.2 ± 10.8 μg/mL for meropenem and 59.0 ± 8.4 μg/mL for vaborbactam. AUC0-8 was 186 ± 33...

OBJECTIVES: Polymyxins have been revitalized to combat carbapenem-resistant Enterobacteriaceae (CRE). However, evaluating the activity of these agents by traditional broth dilution methods is not practical for busy clinical laboratories. We compared polymyxin B (PMB) activity utilizing two quantitative susceptibility testing methods, Etest® and broth microdilution (BMD), against CRE isolates from patients at an academic medical center. METHODS: PMB activity against 70 CRE clinical isolates was determined by EtestP® P according to manufacturer and by BMD according to CLSI guidelines...

The accurate identification of β-lactamases produced by Enterobacteriaceae is a major challenge in clinical laboratories in order to optimize antimicrobial treatment and patient care. We describe here a rapid voltammetric-based method to detect and to discriminate β-lactamase activity in Enterobacteriaceae i.e., penicillinase, cephalosporinase (inducible or overproduced), extended-spectrum beta-lactamase and carbapenemase producers. After a 2-h growth step of the sample under three separate conditions: 1) LB (Luria-Bertani) medium, 2) LB supplemented with 4 μg/mL cefotaxime and 3) LB supplemented with 4 μg/mL cefotaxime and 100 μg/mL potassium clavulanate, the β-lactamase activity was measured by incubating a 0...

Purpose: Highly resistant Gram-negative bacterial infections are associated with high mortality. Increasing resistance to standard therapy illustrates the need for alternatives when treating resistant organisms, especially extended-spectrum beta-lactamase- (ESBL-) producing Enterobacteriaceae . Methods: A retrospective chart review at a community hospital was performed. Patients who developed ESBL-producing infections were included. Patients less than eighteen years old, who were pregnant, or who were incarcerated were excluded...

Carbapenem-resistant Enterobacteriaceae (CRE) has been considered a serious global threat, but carbapenem resistance remains relatively uncommon in E. cloacae , especially in China. The aim of this study was to characterize carbapenem-resistant E. cloacae (CR-ECL) isolates from 2012 to 2016 in Southwest China. Our study revealed that 20 (15.2%) of the 132 CR-ECL isolates obtained from patients were identified as NDM-1, with most isolates carrying the IncFIIA plasmids. Notably, we initially observed that the E...

Klebsiella pneumoniae is rapidly acquiring resistance to all known antibiotics, including carbapenems. Multilocus sequence type ST258 (sequence type 258), carrying a gene encoding the K. pneumoniae carbapenemase ( bla KPC ) on a transmissible plasmid, is the most prevalent carbapenem-resistant Enterobacteriaceae (CRE) in the United States and has disseminated worldwide. Previously, whole-genome sequencing identified core genome single nucleotide variants that divide ST258 into two distinct clades, ST258a and ST258b...

Mosquitoes are intensely studied as vectors of disease-causing pathogens, but we know relatively less about microbes that naturally reside in mosquitoes. Profiling resident bacteria in mosquitoes can help identify bacterial groups that can be exploited as a strategy of controlling mosquito populations. High-throughput 16S rRNA gene sequencing and traditional culture-based methods were used to identify bacterial assemblages in Culex quinquefasciatus Say (Diptera: Culicidae) in a tissue- and stage-specific design...

The gut-liver axis plays a pivotal role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD), which is the third cause of hepatocellular carcinoma (HCC) worldwide. However, the link between gut microbiota and hepatocarcinogenesis remains to be clarified. The aim of this study is to explore what features of the gut microbiota are associated with HCC in cirrhotic patients with NAFLD. A consecutive series of patients with NAFLD-related cirrhosis and HCC (group 1: 21 patients), NAFLD-related cirrhosis without HCC (group 2: 20 patients) and healthy controls (group 3: 20 patients) was studied for gut microbiota profile, intestinal permeability, inflammatory status and circulating mononuclear cells...

Salmonella Typhimurium (Le Minor and Popoff 1987; Enterobacteriales: Enterobacteriaceae) is a pathogen that causes gastroenteritis in humans and can be harbored by house flies. Factors influencing excretion of S. Typhimurium from infected flies have not been elucidated but are essential for assessing transmission potential. We determined the persistence and excretion of a green fluorescent protein (GFP) expressing strain of S. Typhimurium from house flies. Individual male and female flies were fed either sterile Luria-Bertani (LB) broth (controls) or cultures of "high" (~105 colony forming units [CFU]) or "low" (~104 CFU) doses of bacteria (treatments)...
