Herein, we present a distorted square pyramidal mercury complex, [HgII(L)Cl] (1), based on a quinoline-substituted formazan ligand LH[3-Cyano-1,5-(quinolin-8-yl)formazan], which was evaluated for its anti-bacterial activity in vitro. Complex 1 was prepared by refluxing 3-Cyano-1,5-(quinolin-8-yl)formazan ligand and mercury chloride(II) in equimolar quantity and was characterized utilizing a range of analytical methods, including single crystal X-ray diffraction (SCXRD) technique. The crystal packing in complex 1 has been elucidated using supramolecular investigations, which have shown the presence of fascinating Hg-Cl···Hg intermolecular spodium bonds of the order 3.

Background: The genomes of publicly available electroactive Pseudomonas aeruginosa strains are currently limited to in-silico analyses. This study analyzed the electroactive Pseudomonas aeruginosa PBH03 genome using comparative in-silico studies for biotechnological applications.
Objective: Comparative in-silico and experimental analyses were conducted to identify the novel traits of P.

Ocular drug-delivery is one of the most challenging areas owing to nature of ocular tissues. Various nanoformulations have been designed and investigated for drug-delivery to achieve high drug bioavailability. The major focus of preparations available in market is to utilize nanomaterial as drug-carrier, with less focus on developing functional-nanomaterials, which is a key knowledge gap in the field.

Antibiotic secretion plays a pivotal role in bacterial interference competition; yet, the impact of environmental hydration conditions on such competition is not well understood. Here, we investigate how hydration conditions affect interference competition among bacteria, studying the interactions between the antibiotic-producing FZB42 and two bacterial strains susceptible to its antibiotics: 85-10 and DC3000. Our results show that wet-dry cycles significantly modify the response of the susceptible bacteria to both the supernatant and cells of the antibiotic-producing bacteria, compared to constantly wet conditions.

Introduction: Murepavadin is an antimicrobial peptide (AMP) in clinical development that selectively targets LptD and whose resistance profile remains unknown. We aimed to explore genomic modifications and consequences underlying murepavadin and/or colistin susceptibility.
Methods: To define genomic mechanisms underlying resistance, we performed two approaches: 1) a genome-wide association study (GWAS) in a clinical collection (n=496), considering >0.
