Antimicrobial and Cytotoxic Activities of Biogenic Nanoparticles Produced by Cyanobacteria

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The article reviews the green synthesis of biogenic nanoparticles produced by cyanobacteria, highlighting their antimicrobial and cytotoxic properties. These nanoparticles, formed intra‐ or extracellularly, show activity against Gram‐positive and Gram‐negative bacteria as well as fungi and can induce apoptosis in tumor cells.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, Volume 600, Issue 6, Page 864-893, March 2026.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Improving Our Understanding of Salmonella enterica Serovar Paratyphi B through the Engineering and Testing of a Live Attenuated Vaccine Strain

mSphere, 2018
Enteric fever is caused by three Salmonella enterica serovars: Typhi, Paratyphi A, and Paratyphi B sensu stricto. Although vaccines against two of these serovars are licensed (Typhi) or in clinical development (Paratyphi A), as yet there are no ...

Dihydromyricetin Regulates PANoptosis to Protect Salmonella Typhimurium‐Infected Weaned Piglets

Food Frontiers, Volume 7, Issue 2, March 2026.
After DHM pretreatment, piglets were subjected to Salmonella infection. Serum and ileocecal samples from the piglets were collected for TUNEL assay, Western blotting analysis, and metabolomics analysis. The results collectively indicated that DHM could protect piglets from Salmonella infection.

Safety, Efficacy, and Immunogenicity of a Salmonella Paratyphi A Vaccine

New England Journal of Medicine
Salmonella enterica serovar Paratyphi A (also known as S. Paratyphi A) is responsible for more than 2 million cases of enteric fever annually. There are no licensed vaccines against S. Paratyphi A.In a double-blind, randomized, placebo-controlled trial, we evaluated an orally administered live, attenuated S.
