Hypermucoviscosity phenotypic Klebsiella pneumoniae (HV-Kp) serotype K1 is the predominant pathogen of a pyogenic liver abscess, an emerging infectious disease that often complicates septic metastatic syndrome in diabetic patients with poor sugar control. HV-Kpisolates were more resistant to neutrophil phagocytosis

Dihydrodipicolinate synthase (DHDPS) is a key enzyme in lysine biosynthesis and a potential antibiotic target. The enzyme catalyses the condensation of (S)-aspartate semi-aldehyde (ASA) and pyruvate to form dihydrodipicolinate. Constrained diketopimelic acid derivatives have been designed as mimics of the

A nanoscale MOF material NMOF 1 with controllable morphologies is realized whose morphology control has been simulated based on the BFDH method. The targeted NMOF 1 exhibits highly sensitive, selective and instant "turn-on" sensing of bacterial endospores.

Two decades of scientific ocean drilling have demonstrated widespread microbial life in deep sub-seafloor sediment, and surprisingly high microbial-cell numbers. Despite the ubiquity of life in the deep biosphere, the large community sizes and the low energy fluxes in this

We present the synthesis of highly anisotropic nickel nanowires (NWs) and large area, free-standing carpets extending over cm(2) area by simple solution phase chemistry. The materials can be post-synthetically manipulated to produce hybrid tubes, wires, and carpets by galvanic exchange
