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

The 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 ...

Resistance to carbapenems in non-typhoidal Salmonella enterica serovars from humans, animals and food [PDF]

, 2018
Non-typhoidal serovars of Salmonella enterica (NTS) are a leading cause of food-borne disease in animals and humans worldwide. Like other zoonotic bacteria, NTS have the potential to act as reservoirs and vehicles for the transmission of antimicrobial ...

Targeting the Dynamic Susceptibility Window: Time‐Sensitive Photodynamic Synergy With Antibiotics Against Streptococcus spp

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objective Evaluated the antimicrobial efficacy of curcumin‐mediated photodynamic inactivation (PDI) against both sensitive and resistant strains of Streptococcus pneumoniae and Streptococcus pyogenes, as well as its potential to enhance antibiotic effects (amoxicillin, ceftriaxone, erythromycin).

Structural shifts in TolC facilitate Efflux-Mediated β-lactam resistance

Communications Biology
Efflux-mediated β-lactam resistance is a major public health concern, reducing the effectiveness of β-lactam antibiotics against many bacteria. Structural analyses show the efflux protein TolC in Gram-negative bacteria acts as a channel for antibiotics ...

β-lactam antibiotics promote bacterial mutagenesis via an RpoS-mediated reduction in replication fidelity

Nature Communications, 2013
Regardless of their targets and modes of action, subinhibitory concentrations of antibiotics can have an impact on cell physiology and trigger a large variety of cellular responses in different bacterial species.

Evidence for the evolutionary steps leading to mecA-mediated ß-lactam resistance in staphylococci [PDF]

, 2017
The epidemiologically most important mechanism of antibiotic resistance in Staphylococcus aureus is associated with mecA–an acquired gene encoding an extra penicillin-binding protein (PBP2a) with low affinity to virtually all β-lactams.

Genome‐wide screen reveals a universal role of ATP in ciprofloxacin tolerance among genetically distinct Escherichia coli persisters

mLife, EarlyView.
Abstract Bacterial persisters show tolerance to bactericidal antibiotics and play essential roles in chronic infections; however, the general mechanisms underlying persister formation and antibiotic tolerance remain insufficiently characterized. In this study, the Escherichia coli Keio library was used to identify genes involved in ciprofloxacin ...

Synthetic Lethality Reveals Mechanisms of Mycobacterium tuberculosis Resistance to β-Lactams

mBio, 2014
Most β-lactam antibiotics are ineffective against Mycobacterium tuberculosis due to the microbe’s innate resistance. The emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains has prompted interest to repurpose this class of ...

Optimizing Guideline-Recommended Antibiotic Doses for Pediatric Infective Endocarditis [PDF]

, 2016
The American Heart Association recently published an updated scientific statement on the management of infective endocarditis in childhood. The recommendations included for vancomycin, aminoglycoside, and β-lactam dosing and monitoring are based ...
