Drivers of bat researchers’ intent to adopt field hygiene practices

Conservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

The FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Synthetic O‐Polysaccharide Backbone Units for a Single Antigen Vaccine Against Two Major Non‐Typhoidal Salmonella Serovars

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against
