Nanostructured Ti–6Al–4V Reduces Adhesion of Several Bacterial Species: An In Vitro Study

Small Science, Volume 6, Issue 8, August 2026.
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

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
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.

Recent Advances in the Molecular Mechanisms of Bacterial Anti‐Phage Defence Systems

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
Panoptes as an example for an antiphage system consists of OptS producing a cyclic dinucleotide that prevents activation of OptE, a transmembrane protein. Phage T4 infection introduces the sponge protein Acb2 that adsorbs the cyclic dinucleotide thus activating OptE which disrupts the cell membrane aborting phage infection.

Occurrence and Distribution of Environmental Pseudomonas aeruginosa From Hospitals in Bangladesh Reveals Diverse Strain Families, Multidrug Resistance, and Biofilm Formation

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
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

Genetic Composition Is Unrelated to Song Content in a Wild Passerine

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT Birdsong is a key sexual signal that varies substantially among individuals and populations. Understanding whether song similarity reflects genetic similarity is central for evaluating its role in sexual selection, population divergence and evolutionary dynamics, although partial vocal learning can obscure this relationship in many species ...

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility

Molecular Microbiology, Volume 126, Issue 2, Page 173-189, August 2026.
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 ...

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, Volume 49, Issue 8, Page 4823-4839, August 2026.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and
