Impact of Regional Hepatic Immunosuppression With Budesonide on Bacterial Elimination in Porcine Abdominal Sepsis

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 8, September 2026.
ABSTRACT Introduction The liver is essential for bacterial elimination, preventing intestinal bacteria from entering the systemic circulation, and for producing inflammatory cytokines. Glucocorticoids have been reported to exert heterogeneous effects on bacterial clearance in sepsis.

Decoding Akkermansia muciniphila Effector Biology: From Microbial Molecules to Host Outcomes

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Schematic overview of the proposed gut–brain axis mechanisms linking Akkermansia muciniphila to host outcomes. A. muciniphila‐derived signals, including SCFAs and P9/GLP‐1‐related endocrine pathways, may influence epithelial barrier integrity, inflammatory responses, systemic immune signaling, and neural communication through the enteric nervous system,

Investigations on the Specificity of the Limulus Test for the Detection of Endotoxin [PDF]

Applied Microbiology, 1974
Lysates obtained from amoebocytes of Limulus polyphemus , the horseshoe crab, showed gel formation after the addition of bacterial endotoxin. In contrast to living gram-negative bacteria, viable gram-positive microorganisms did not cause gelation of lysate.

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1847-1860, August 2026.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.
