Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Characterization of novel beta-galactosidase activity that contributes to glycoprotein degradation and virulence in Streptococcus pneumoniae.

, 2010
The pneumococcus obtains its energy from the metabolism of host glycosides. Therefore, efficient degradation of host glycoproteins is integral to pneumococcal virulence.

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Important Virulence Factors and Related Genes in Uropathogenic E. coli and their Relation to Fluoroquinolone Resistance

, 2018
Escherichia coli (E. coli) is the predominant pathogen causing urinary tract infection. E. coli expresses a wide spectrum of virulence factors that enable it to cause the disease. The present study was conducted on 50 E.

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Advances and perspectives in animal models of human hepatitis A virus

Animal Models and Experimental Medicine, EarlyView.
Following HAV infection, humans, non‐human primates, and Ifnar1−/− mice develop characteristic manifestations of hepatitis A, including fecal viral shedding, elevated serum ALT levels, and inflammatory cell infiltration in the liver. In contrast, HAV‐infected human liver chimeric mice exhibit fecal viral shedding but do not develop clinical features of

Helicobacter pylori virulence factors in duodenal ulceration: A primary cause or a secondary infection causing chronicity

, 2006
Reports from countries with a high prevalence of Helicobacter pylori. (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration, suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It

Dose‐dependent pathogenicity and inflammatory imbalance in severely immunodeficient mice infected with mpox virus

Animal Models and Experimental Medicine, EarlyView.
This study establishes an NPG (NOD.Cg‐Prkdcscid Il2rgtm1/Vst) mouse model for severe monkeypox virus infection in immunocompromised hosts, demonstrating dose‐dependent disease severity and revealing that unbalanced pro‐inflammatory cytokine release drives pathogenesis, providing insights for therapeutic interventions. Abstract The global spread of mpox
