Malassezia-Induced Skin Inflammation and Fungal Burden Analysis in a Murine Model
0 Views •
2025
This video demonstrates Malassezia-induced skin infection in mice. Malassezia oil suspension is applied over the wounded ear, triggering inflammation and swelling of the ear tissue. Later, the ears are dissected, homogenized, and spread on an agar plate for growth. The number of colonies indicates the fungal burden resulting from skin inflammation.

2025
This video demonstrates a method to quantify fungal infection in zebrafish larvae. Fungal spores are microinjected into the larval hindbrain ventricle, and the larvae are incubated to allow infection development. Infected larvae are harvested at defined intervals, and infection progress is assessed by enumerating colony-forming units.

2025
This video demonstrates the establishment of rice plant leaf infection through wounding inoculation with Magnaporthe grisea mycelium. The fungal spore-derived germ tube penetrates the epidermal layer, resulting in tissue infection and lesions on the leaves. This method aids pathotype screening and improves plant resistance understanding for molecular breeding.

This video demonstrates a technique to establish the pathogenic fungus Magnaporthe grisea infection in rice plant leaves. The fungal conidia suspension is sprayed on sections of rice leaf, and the disease progression is assessed by scoring the formation of necrotic lesions.
FAQs
Keratin-rich tissues provide both an attachment site and a nutrient source. Fungi can adhere to the outer skin, hair, or nails and use enzymes that help them access keratin-associated nutrients. This combination supports colonization or invasion at superficial sites and makes keratin processing a central part of the host-microbe interaction.
Skin immunity responds at several linked levels rather than through inflammation alone. Barrier responses act at the surface, inflammatory signaling coordinates local defense, and recruited immune cells participate in limiting the organism. Examining these layers helps explain how host defenses contain superficial infection and why altered susceptibility can allow disease to persist.
Dermatophytes, yeasts, and other fungi can all be associated with skin infection, but identifying the causative organism provides essential biological context. Organism identification connects the observed infection with the relevant host-microbe interaction and supports an informed choice of antifungal therapy directed at controlling fungal growth.
Clinical evaluation provides the initial assessment, while microscopy and culture offer laboratory approaches for identifying the causative organism. Molecular testing may also be used when appropriate. Using these methods helps distinguish the infectious cause from the clinical presentation alone and supplies information needed to guide antifungal management.
Both topical and systemic antifungal therapies are intended to target fungal growth, but they represent different treatment approaches. The available clinical information supports viewing them as complementary options rather than interchangeable descriptions of the same intervention. Selecting an approach requires considering the infection being evaluated and the identified fungal cause.
These infections provide a model for studying how a tissue barrier, fungal nutrient acquisition, inflammatory signaling, and immune-cell recruitment interact. Research can therefore connect organism detection and treatment with host defense mechanisms. It also helps investigate why disease remains persistent in susceptible hosts, making the topic relevant to both clinical evaluation and immunology.
