Extracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...

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.

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

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
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
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
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
