Plasmid-determined cytotoxicity in Yersinia pestis and Yersinia pseudotuberculosis [PDF]

Infection and Immunity, 1986
Yersinia pestis KIM5 was found to be cytotoxic for the IC21 and P388D1 mouse macrophage cell lines, as well as for resident peritoneal macrophages from C57BL/6 mice. Affected cells phagocytosed KIM5 inefficiently, became spherical, detached readily from culture dishes, and retained 51Cr poorly.

Bordetella BcrH1 and BcrH2 Are Specific Chaperones for the Pore‐Forming Complex

Microbiology and Immunology, Volume 70, Issue 2, Page 57-67, February 2026.
ABSTRACT Bordetella has a type III secretion system that secretes virulence proteins crucial to the establishment of infection. The genes encoding components of the Bordetella type III secretion system are located in the bsc region on the chromosome. This region includes the bcrH1 and bcrH2 genes, which respectively encode the proteins BcrH1 and BcrH2.

Commentary on Seersholm Et al.: Yersinia pestis Infection Is Not Synonymous With Deadly Plague in Neolithic Scandinavia

American Journal of Biological Anthropology, Volume 189, Issue 1, January 2026.
ABSTRACT Objectives Emerging genomic evidence has identified ancestral strains of Yersinia pestis in ancient human populations, which has sparked debates about its pathogenic role in later Neolithic societies. Here, we review published evidence linking anthropological and biological data reflecting the past natural history of Y.

YopJ-induced caspase-1 activation in Yersinia-infected macrophages: independent of apoptosis, linked to necrosis, dispensable for innate host defense. [PDF]

PLoS ONE, 2012
Yersinia outer protein J (YopJ) is a type III secretion system (T3SS) effector of pathogenic Yersinia (Yersinia pestis, Yersinia enterocolitica and Yersinia pseudotuberculosis) that is secreted into host cells. YopJ inhibits survival response pathways in

Developmental Impact of Maternal Immune Activation on the Fetal Immune System and Lung

European Journal of Immunology, Volume 56, Issue 1, January 2026.
Maternal immune activation triggers elevated cytokines (IL‐6 and IL‐17A), disrupting fetal immune system development. This not only alters hematopoietic stem cell balance but also leads to ILC2 hyperactivation in the lung, which could potentially affect susceptibility to allergic diseases in the offspring.

Diagnostics and epidemiology of Yersinia pseudotuberculosis

, 2010
Yersinia pseudotuberculosis is an animal pathogen widespread in nature. The bacterium has caused infections in humans occasionally. Most of the reported Y. pseudotuberculosis -infections are sporadic, and the sources and vehicles of Y. pseudotuberculosis

Interaction of Staphylococcus aureus di‐iron Repair of Iron Centers protein with the iron–sulfur cluster assembly SUF system

Protein Science, Volume 35, Issue 1, January 2026.
Abstract Repair of Iron Centers (RIC) proteins are present in several pathogens, including Staphylococcus aureus, contributing to resistance to nitroxidative stress and virulence. In this work, we investigated the molecular mechanisms by which S. aureus RIC facilitates iron mobilization, through structural analyses and functional studies.

Effect of High‐Pressure Processing Operating Parameters on Microbial Inactivation and Bioactive Protein Preservation in Bovine Milk: A Systematic Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT In the U.S., bovine milk is processed using thermal pasteurization to ensure microbial safety. However, this process alters the structure of heat‐sensitive bioactive proteins associated with the functional benefits of raw milk, including antimicrobial, immunomodulatory, and antioxidant proteins.
