Case Reports in Pulmonology, Volume 2026, Issue 1, 2026.Necrotizing pneumonia and empyema caused by Fusobacterium necrophorum are uncommon. The classical presentation of Lemierre′s syndrome, characterized by pharyngotonsillitis and internal jugular vein thrombosis, is not always observed, and incomplete and atypical variants can cause diagnostic uncertainty and delay in treatment.

Effects of Aggregatibacter actinomycetemcomitans leukotoxin on endothelial cells
Microbial Pathogenesis, 2013 Aggregatibacter actinomycetemcomitans is a human pathogen that produces leukotoxin (LtxA) as a major virulence factor. In this study the effect of LtxA on microvascular endothelial cell viability and phenotype was studied. High doses of single LtxA treatment (500 ng/ml to 5 μg/ml) significantly and irreversibly decreased cell proliferation and induced ...

International Journal of Food Science, Volume 2026, Issue 1, 2026.Staphylococcus aureus is a leading cause of foodborne diarrhea, primarily due to staphylococcal enterotoxins (SEs). This study employed whole‐genome sequencing to characterize 106 S. aureus isolates from diarrheal patients in East China (2019–2024). We identified 23 sequence types, with ST398 (22.6%) and ST5 (7.5%) among the most prevalent.

Periodontal Ecosystem and Clinical Implications of the Oral Microbiome: A Narrative Review
International Journal of Dentistry, Volume 2026, Issue 1, 2026.Background Periodontal disease, although widely documented, remains one of the leading causes of tooth loss worldwide. This situation can be attributed to patients’ difficulty in following treatment protocols and to an incomplete understanding of the disease’s mechanisms, which could be explored to develop new therapies.

Concordance in diagnostic testing for respiratory pathogens of bighorn sheep
Wildlife Society Bulletin, 2016 Reliable diagnostic tests are essential for disease investigation and management. This is particularly true for diseases of free‐ranging wildlife where sampling is logistically difficult precluding retesting.

Role of carriers in the transmission of pneumonia in bighorn sheep (Ovis canadensis)
Biology Open, 2016 In the absence of livestock contact, recurring lamb mortality in bighorn sheep (Ovis canadensis) populations previously exposed to pneumonia indicates the likely presence of carriers of pneumonia-causing pathogens, and possibly inadequate maternally ...

The FASEB Journal, Volume 39, Issue 23, 15 December 2025.Salivary multiomics from healthy, PD, RA, and PD‐RA cohorts identified PD−/RA‐linked microbial and metabolic signatures. We then transplanted salivary microbiota from a PD donor or a healthy donor into collagen‐induced arthritis mice. PD microbiota colonized the gut, reshaped communities, weakened epithelial tight junctions, and provoked systemic ...

Journal of Oral Microbiology, 2016 Background: Aggressive periodontitis is associated with the presence of Aggregatibacter actinomycetemcomitans, a leukotoxin (Ltx)-producing periodontal pathogen. Ltx has the ability to lyse white blood cells including neutrophils.

Human CYP4F3s are the main catalysts in the oxidation of fatty acid epoxides
Journal of Lipid Research, 2004 CYP4F isoforms are involved in the oxidation of important cellular mediators such as leukotriene B4 (LTB4) and prostaglandins. The proinflammatory agent LTB4 and cytotoxic leukotoxins have been associated with several inflammatory diseases.
