Massive culture-based approach for the screening of AmpC, ESBL, and carbapenemase producers from rectal swabs

open access: yesMicrobiology Spectrum
Gram-negative bacilli-producing beta-lactamases are major causes of difficult-to-treat infections, especially the AmpC, extended-spectrum beta-lactamases (ESBL), and carbapenemase types. Their spread within and outside hospital settings demands effective

Escape mutations circumvent a tradeoff between resistance to a beta-lactam and resistance to a beta-lactamase inhibitor

open access: yesNature Communications, 2020
Beta-lactam antibiotics and beta-lactamase inhibitors compete for the same binding site on beta-lactamases; thus, mutations that increase beta-lactamase activity likely increase also susceptibility to the inhibitor. Here, Russ et al.

Mortality after broad‐ versus narrow‐spectrum antibiotic treatment for patients with nursing and healthcare‐associated pneumonia: A nationwide retrospective cohort study

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Nursing and healthcare‐associated pneumonia (NHCAP) is defined as pneumonia occurring in individuals with frequent healthcare contact, such as residents of care facilities or patients with impaired activities of daily living. The effectiveness of broad‐spectrum antibiotics in treating NHCAP remains unclear.

Novel Computational Protocols for Functionally Classifying and Characterising Serine Beta-Lactamases.

open access: yesPLoS Computational Biology, 2016
Beta-lactamases represent the main bacterial mechanism of resistance to beta-lactam antibiotics and are a significant challenge to modern medicine. We have developed an automated classification and analysis protocol that exploits structure- and sequence ...

Evaluation of phenotypic tests for the detection of AmpC beta-lactamase in clinical isolates of Escherichia coli

open access: yesIndian Journal of Pathology and Microbiology, 2013
Background: AmpC beta lactamases are cephalosporinases that confer resistance to a wide range of beta lactam drugs thereby causing serious therapeautic problem.

Anterolateral‐Thigh Fascia Lata Free Flap Versus Fibula Free Flap for Mandibular Osteoradionecrosis

open access: yesThe Laryngoscope, EarlyView.
The anterolateral thigh fascia lata “rescue” free flap has been employed as a novel tool in the treatment of advanced partial thickness mandibular osteoradionecrosis. Compared with the traditional fibula free flap for the same indication, the “rescue” flap provides similar outcomes in terms of disease resolution, superior functional outcomes, and ...

Prevalence and characterization of hybrid blaCTX-M among Escherichia coli isolates from livestock and other animals [PDF]

open access: yes, 2015
This study investigated 248 extended-spectrum β-lactamase-producing Escherichia coli isolates from 2012 to 2013 for hybrid blaCTX-M genes. blaCTX-M genes were detected in 228 isolates of which 14 isolates were hybrid blaCTX-M positive (6 blaCTX-M-123, 6 ...
