Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, EarlyView.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...

Formation of carbohydrate-functionalised polystyrene and glass slides and their analysis by MALDI-TOF MS [PDF]

, 2012
Glycans functionalised with hydrophobic trityl groups were synthesised and adsorbed onto polystyrene and glass slides in an array format. The adsorbed glycans could be analysed directly on these minimally conducting surfaces by MALDI-TOF mass ...

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

Advanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

Quantitative Approach to Single-Nucleotide Polymorphism Analysis Using MALDI-TOF Mass Spectrometry

BioTechniques, 2000
Pooling of DNA samples before genotyping is a valuable means of streamlining large-scale genotyping efforts in disease association studies, single-nucleotide polymorphism (SNP) validation or mutant allele screening programs.

Identification of dermatophytes by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry [PDF]

, 2017
In this study we evaluated the suitability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for the identification of dermatophytes in diagnostic laboratories.

Structure analysis of biologically important prokaryotic glycopolymers [PDF]

, 2013
Of the many post-translational modifications organisms can undertake, glycosylation is the most prevalent and the most diverse. The research in this thesis focuses on the structural characterisation of glycosylation in two classes of glycopolymer (

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing

Advanced Science, EarlyView.
Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial

3‐Deoxy‐3‐Fluoro Mannuronic Acid Alginates: Stereoselective Automated Synthesis and Conformational Behaviour

Angewandte Chemie, EarlyView.
The impact of C‐3 fluorination on the synthesis and conformation of alginate oligosaccharides is investigated. A C‐3‐fluoro mannuronic acid building block is generated and shown to react with high β‐selectivity. Automated glycan assembly enables access to uniquely fluorinated mannuronic acid alginates where deoxyfluorination is shown not to perturb the

Identification Of Endophytic Bacteria From Curcuma Zedoaria Based On Protein Profile Using Maldi-tof Mass Spectrometry [PDF]

, 2018
Valid identification of microorganisms is a vital information to establish culture collections. Currently, molecular approach based on 16S rDNA is widely used for bacterial identification. This approach is however, time consuming and expensive.
