Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

Failure to trigger the autolytic enzymes in minicells of Escherichia coli

, 1992
Minicells from Escherichia coli P678-54 are refractory towards procedures known to induce bacteriolysis of DNA-containing E. coli cells. Although still engaged in murein synthesis, minicells could not be lysed by penicillin G.

Mutations of the Listeria monocytogenes Peptidoglycan N-Deacetylase and O-Acetylase Result in Enhanced Lysozyme Sensitivity, Bacteriolysis, and Hyperinduction of Innate Immune Pathways†

, 2011
Listeria monocytogenes is a Gram-positive intracellular pathogen that is naturally resistant to lysozyme. Recently, it was shown that peptidoglycan modification by N-deacetylation or O-acetylation confers resistance to lysozyme in various Gram-positive ...
