This US-based study reveals that M. canis genotype correlates with disease severity in cats, identifies three genetic clusters, and confirms the dominance of the MAT1-1 mating type. Conserved virulence genes (SSU1, SUB3) offer potential diagnostic utility.

This review details the enzymatic and genetic virulence arsenal of Microsporum canis, highlighting understudied factors like biofilms and dipeptidylpeptidases. Greater insight into these mechanisms could improve treatment and prevention strategies.

This study identified a metalloprotease gene family in Microsporum canis and confirmed in vivo expression of MEP2 and MEP3 during infection. MEP3, a keratinolytic enzyme, was expressed recombinantly and may contribute to fungal virulence, supporting its use in vaccine development.

Bee venom showed partial antifungal activity against resistant M. canis isolates, supporting its evaluation as a potential topical therapeutic. While not as potent as terbinafine, BV outperformed fluconazole and amphotericin B in susceptible isolates, highlighting its promise amid rising antifungal resistance.

A multi‑ethnic review summarising >80 genetic loci underlying Graves’ disease, their clinical correlates and emerging precision‑medicine applications.

This review links genetics, hormones, environment and especially viral exposures—EBV and HCV—to the Th1‑centric immunopathology of Graves’ disease, highlighting chemokine signatures relevant to microbiome‑based risk models.

Mendelian‑randomization of 18,340 MiBioGen participants and > 349k FinnGen controls identifies 32 gut genera with causal roles—some protective, others harmful—across six thyroid diseases, highlighting therapeutic microbiome targets.

Mendelian‑randomization of Japanese GWAS data shows a bidirectional genetic link between Graves’ disease and rheumatoid arthritis. The findings reinforce shared autoimmune pathways, highlight overlapping Prevotella‑dominant gut dysbiosis, and support reciprocal clinical screening and microbiome‑targeted interventions.

Graves Disease potentiates depression via autoimmune cytokines, hormonal excess and gut‑microbiome shifts. This review consolidates epidemiology and mechanisms, highlighting microbial signatures (Prevotellaceae, SCFA depletion) of translational interest.

Mendelian-randomization of East-Asian GWAS data shows Crohn disease genetics raise Graves disease risk, while ulcerative colitis genetics are protective, highlighting microbiome-immune pathways linking gut and thyroid autoimmunity.

This study identified a microbiome signature in Graves’ disease marked by reduced microbial richness and elevated Prevotella_9 and Haemophilus, with losses in Faecalibacterium and Alistipes, supporting a role for gut dysbiosis in GD pathogenesis.

This bidirectional Mendelian Randomization (MR) study establishes a causal link between Graves’ disease and gut microbiome alterations, confirming thyroid–gut axis interactions and identifying key microbial taxa as risk or protective factors.

This review maps the bidirectional interactions between toxic and essential metals and the gut microbiota, detailing microbial shifts and host impacts. It highlights specific microbial taxa disrupted by metals like arsenic, cadmium, and nickel, providing insight into metal-driven dysbiosis and its implications for disease pathogenesis.

This systematic review found insufficient evidence to confirm that physical exercise reduces endometriosis risk or symptoms, though some data suggest a potential protective effect. Well-designed controlled trials are needed to clarify the role of exercise in endometriosis prevention and management.

Guar gum is a water-soluble and gel-forming x,x soluble fiber derived from the guar bean (Cyamopsis tetragonoloba), an annual legume crop that is primarily cultivated in India and Pakistan, along with small quantities in the United States, Australia, and Africa. Guar gum is commonly found in foods and dietary supplements. Guar gum has several potential health benefits: […]

A case report highlights hibiscus tea’s phytoestrogens potentially lowering DVT risk while interfering with IVF hormone therapy, emphasizing a need for cautious use and further research.

Staphylococcus aureus is a versatile skin and mucosal commensal that can transition into a highly virulent pathobiont. Known for its immune-evasive strategies, toxin production, and antibiotic resistance, it plays a significant role in chronic infections and microbiome imbalance.

This study shows that Staphylococcus aureus uses MntABC and MntH transporters to overcome host-imposed manganese starvation via calprotectin, preserving SOD activity and enabling systemic infection.

This review highlights Staphylococcus aureus as a multifaceted pathogen with niche-specific colonization, immune evasion, iron acquisition strategies, and extensive resistance mechanisms, emphasizing its microbiome interactions and emerging therapeutic targets.

This review examines bacterial resistance systems to toxic metals, detailing efflux pumps, ATPases, and metallothioneins. It explores their mechanisms, gene regulation, and clinical or environmental relevance.

This review outlines how S. aureus leverages diverse virulence factors—α-toxin, leukocidins, biofilms, and immune evasion mechanisms—regulated by systems like Agr to persist and cause disease. It discusses anti-virulence strategies and implications for targeted therapies.

Metallophores in S. aureus enable metal acquisition and virulence; disrupting these systems may offer novel antimicrobial strategies.

Disabling NADH-dependent respiration in Staphylococcus aureus impairs biofilm and alpha-toxin production via fatty acid-mediated repression of the SaeRS system, significantly reducing virulence. These findings highlight metabolic pathways as promising antimicrobial targets.

This study sequenced and analyzed plasmids from poultry-associated Staphylococcus aureus, uncovering diverse resistance and virulence genes, novel mobilizable plasmids, and highlighting poultry as a reservoir for clinically relevant resistance determinants transferable to human strains.
