It is a type of dermatophyte that colonizes keratinized tissues (primarily hair) causing infection. [2] The fungus is characterized by its spindle-shaped macroconidia (7–30 × 35–160 μm ), clavate microconidia (2.5–3.5 × 4–7 μm) as well as its pitted or spiny external walls.
Microsporum canis produces infections of scalp and body sites, creating highly inflammatory lesions associated with hair loss. [3] Infection by this species can often be detected clinically using Wood's lamp , which causes infected tissues to fluoresce bright green [ 4 ] [ 9 ] Fluorescence is attributed to metabolite pteridine , which is ...
Microsporum gypseum. Microsporum is a genus of fungi that causes tinea capitis, tinea corporis, ringworm, and other dermatophytoses (fungal infections of the skin). Microsporum forms both macroconidia (large asexual reproductive structures) and microconidia (smaller asexual reproductive structures) on short conidiophores.
Specifically, scalp fungal infections are often caused by fungi in the microsporum and trichophyton genera. Scalp fungus can cause a variety of symptoms, including: Dry, scaly skin. Redness ...
At least eight species of dermatophytes are associated with tinea capitis. Cases of Trichophyton infection predominate from Central America to the United States and in parts of Western Europe. Infections from Microsporum species are mainly in South America, Southern and Central Europe, Africa and the Middle East. The disease is infectious and ...
Microsporum gypseum is a soil-associated dermatophyte that occasionally is known to colonise and infect the upper dead layers of the skin of mammals. [1] The name refers to an asexual "form-taxon" that has been associated with four related biological species of fungi: the pathogenic taxa Arthroderma incurvatum, A. gypsea, A. fulva and the non-pathogenic saprotroph A. corniculata.
Piedraia hortae is a dermatophyte and causes a superficial fungal infection known as black piedra, which causes the formation of black nodules on the hair shaft and leads to progressive weakening of the hair. [3] The infection usually infects hairs on the scalp and beard, but other varieties tend to grow on pubic hairs.
Exam: The provider will look at your scalp, paying careful attention to signs of infection, redness, and bumps. Skin Swab: A swab of the affected area may be taken to be looked at more closely ...
