Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments
Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Segmentally Variable Genes: A New Perspective on Adaptation [PDF]
Genomic sequence variation is the hallmark of life and is key to understanding diversity and adaptation among the numerous microorganisms on earth. Analysis of the sequenced microbial genomes suggests that genes are evolving at many different rates.

Their bioactive constituents act through antioxidant, anti‐inflammatory, and metabolic‐regulating mechanisms, validating their classification as functional foods. Evidence from clinical and biochemical studies largely supports these benefits, although some claims stem from preliminary or in vitro findings.

DNA gyrase could be a crucial regulatory factor for growth and survival of Mycobacterium leprae
Leprosy, an important infectious disease in humans caused by Mycobacterium leprae (Mle), remains endemic in many countries. Notably, the pathogen cannot be cultured in vitro, except in mouse footpads in vivo.

The latch modulates nucleotide and DNA binding to the helicase-like domain of Thermotoga maritima reverse gyrase and is required for positive DNA supercoiling [PDF]
Reverse gyrase is the only topoisomerase that can introduce positive supercoils into DNA in an ATP-dependent process. It has a modular structure and harnesses a helicase-like domain to support a topoisomerase activity, thereby creating the unique ...

Extensive structure‐activity relationship study of albicidin’s C‐terminal dipeptidic p‐aminobenzoic acid moiety [PDF]
Albicidin is a recently described natural product that strongly inhibits bacterial DNA gyrase. The pronounced activity, particularly against Gram‐negative bacteria, turns it into a promising lead structure for an antibacterial drug.

Mechanism of Inhibition of DNA Gyrase by ES‐1273, a Novel DNA Gyrase Inhibitor [PDF]
AbstractWe investigated the mode of action of ES‐1273, a novel DNA gyrase inhibitor obtained by optimization of ES‐0615, which was found by screening our chemical library using anucleate cell blue assay. ES‐1273 exhibited the same antibacterial activity against S. aureus strains with amino acid change(s) conferring quinolone‐ and coumarin‐resistance as

Iranian clinical Stenotrophomonas maltophilia isolates showed high susceptibility to trimethoprim/sulfamethoxazole, minocycline, and levofloxacin, but marked resistance to ceftazidime and ticarcillin‐clavulanate, alongside widespread biofilm production and resistance genes.

Guiding strand passage: DNA-induced movement of the gyrase C-terminal domains defines an early step in the supercoiling cycle [PDF]
DNA gyrase catalyzes ATP-dependent negative supercoiling of DNA in a strand passage mechanism. A double-stranded segment of DNA, the T-segment, is passed through the gap in a transiently cleaved G-segment by coordinated closing and opening of three ...
