De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
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.

One Health Insights From Pteropus medius: Nipah Virus Spillover, Microbiota, and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Environmental and anthropogenic drivers of antibiotic resistance dissemination. The cycle reinforces how anthropogenic inputs, such as sewage, animal dung, hospital effluent, and agricultural runoff bring resistant bacteria and antibiotic residues into soil and water.

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1529-1540, August 2026.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

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.

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.

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 ...

Lethality of Brucella microti in a murine model of infection depends on the wbkE gene involved in O-polysaccharide synthesis

Virulence, 2019
Brucella microti was isolated a decade ago from wildlife and soil in Europe. Compared to the classical Brucella species, it exhibits atypical virulence properties such as increased growth in human and murine macrophages and lethality in experimentally ...
