Escherichia coli is a rare cause of endocarditis. This article reports an 82-year-old male with a mechanical aortic valve replacement who was admitted for fever and fatigue. He was diagnosed with a tricuspid valve endocarditis caused by an extended spectrum beta lactamase producing Escherichia coli following positive blood cultures and echocardiogr...

Bacterial resistance to existent antibiotherapy is a perpetual internationally-recognized problem. Year after year, there is a continuous need for novel antibacterial drugs and this research and development efforts recently resulted in few new drugs or combination of drugs proposed for the use into the clinic. This review focuses on the novel US FD...
Elizabethkingia genus is emerging in hospitals and resistant to multiple antibiotics. The intrinsic imipenem resistance of Elizabethkingia genus is related to two chromosome-encoded metallo-beta-lactamases (MBLs), BlaB and GOB. This study was aimed to investigate the in vitro activity of imipenem, vancomycin, and rifampicin in clinical Elizabethkin...

To investigate the susceptibility profiles amongst ertapenem-non-susceptible non-carbapenemase-producing Enterobacterales (ETP-NS-non-CPE) isolates. Minimum inhibitory concentrations (MICs) of 404 ETP-NS-non-CPE isolates collected from different intra-abdominal infection (IAI) sites amongst patients in the Asia-Pacific region during 2008-2014 were ...

Background and Objectives: In recent years, reports of Acinetobacter strains resistant to all known antibiotics have caused a great concern in medical communities. Overexpression of efflux pumps is one of the major causes of resistance in bacteria. The aim of this study was to investigate the role of efflux pumps in conferring resistance to imipene...

Imipenem is a carbapenem antibiotic. However, Imipenem could not be marketed owing to its instability and nephrotoxicity until cilastatin, an inhibitor of renal dehydropeptidase-I (DHP-I), was developed. In present study, the potential roles of renal organic anion transporters (OATs) in alleviating the nephrotoxicity of imipenem by cilastatin were ...
Relebactam is a small molecule β-lactamase inhibitor under clinical investigation for use as a fixed-dose combination with imipenem/cilastatin. Here we present a translational pharmacokinetic/pharmacodynamic mathematical model to support optimal dose selection of relebactam. Data derived from in vitro checkerboard and hollow fiber infection studies...

Due to the rapid emergence of multidrug-resistant isolates, Campylobacter jejuni (C. jejuni) has been classified as a member of the priority pathogens group. This study aimed to determine the prevalence, antibiotic resistance patterns and source tracking of clinical C. jejuni isolates from paediatric diarrhoeal patients in Pakistan. A total of 150 ...
The Bay of Bengal is known as the epicenter for seeding several devastating cholera outbreaks across the globe. Vibrio cholerae, the etiological agent of cholera, has extraordinary competency to acquire exogenous DNA by horizontal gene transfer (HGT) and adapt them into its genome for structuring metabolic processes, developing drug resistance, and...

Pseudomonas aeruginosa is an important aetiological agent causing pneumonia, urinary tract infections and bacteraemia. High antibiotic use in nosocomial settings and for immunocompromised conditions results in increasing multidrug resistance. This study analysed the antimicrobial resistance profile of P. aeruginosa isolates in an HIV setting. A tot...
