De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

MYC in Oncogenesis and Therapeutic Implications
The MYC oncogene family (c‐MYC, N‐MYC, L‐MYC) functions as a central transcriptional hub orchestrating cancer progression through multiple interconnected pathways. This graphical abstract illustrates MYC's role as a multidimensional regulator positioned at the nexus of tumor microenvironment remodeling, metabolic reprogramming, and therapeutic ...

Nanostructured Ti–6Al–4V Reduces Adhesion of Several Bacterial Species: An In Vitro Study
Alkaline etching transforms Ti–6Al–4V into nanostructured, highly hydrophilic surfaces with thicker oxide layers and selective alloy depletion. These physicochemical changes reduce early bacterial adhesion across multiple species by limiting effective nanoscale contact points, while osteoblast‐like cells retain good attachment and spreading.

Bovine bacterial abortion caused by Escherichia coli infection
Abstract A 3‐year‐old, 500 kg Holstein cow aborted at 7 months of gestation. On histological evaluation of the fetal lungs, abundant neutrophils infiltrated the alveolar spaces, bronchi and bronchioles with intralesional Gram‐negative bacteria, immunolabelled with Escherichia coli immunohistochemistry.

TolC is identified as an essential component of the mixed‐linkage β‐glucan (MLG) biosynthetic machinery in Sinorhizobium meliloti, likely enabling polymer export. Co‐expression of tolC, bgsBA, and pleD* significantly enhances MLG production and enables its synthesis in non‐native bacterial hosts.

Environmental reservoirs in Bangladeshi hospitals harbor phylogenetically diverse, multidrug‐resistant Pseudomonas aeruginosa with extensive biofilm‐forming capacity and class 1 integron‐associated resistance genes. These findings highlight hospital environments as persistent sources of antimicrobial resistance dissemination and underscore the need for

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales
ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...
