Which fungi have arthroconidia?
If arthroconidia are formed only within the hair and the hair’s cuticle remains intact, the invasion is endothrix. This is most commonly seen in T. tonsurans disease. When the fungus produces arthroconidia inside and along the outside of the hair shaft, ectothrix invasion has occurred.
What causes arthroconidia?
Arthroconidia are a type of fungal spore typically produced by segmentation of pre-existing fungal hyphae.
How are dermatophyte infections transmitted?
Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites.
What disease do dermatophytes cause?
The diseases that result from a dermatophyte infection are known as tineas. The location of the disease on the body further defines the disease, so that tinea pedis are dermatophyte infections of the feet, tinea cruris of the genitals, tinea corporis of the torso, and tinea capitis of the head.

What kills dermatophyte fungus?
Treatment with oral terbinafine, itraconazole, and griseofulvin has been used with good efficacy. Terbinafine 250 mg daily for 2–4 weeks may be preferred over itraconazole and griseofulvin in patients on multiple drugs.
How do you treat dermatophyte infection?
Ringworm on the skin like athlete’s foot (tinea pedis) and jock itch (tinea cruris) can usually be treated with non-prescription antifungal creams, lotions, or powders applied to the skin for 2 to 4 weeks.

Is White Piedra an STD?
White piedra is an uncommon infection caused by yeasts of the genus Trichosporon, namely, Trichosporon ovoides (scalp hair), Trichosporon inkin (pubic hair), and Trichosporon asahii (rare in piedra). The infection occurs in both the tropics and temperate zones.
How do Arthroconidia reproduce?
A large variety of fungi are known to produce asexual spores known as arthroconidia. These propagules are formed by segmentation of existing hyphae and may form by several mechanisms. The specific processes of formation may lead to acropetal, basipetal, or random formation of endoarthroconidia or exoarthroconidia.
How long can dermatophytes live?
The fungal spores can also stay alive on clothing, bedding, and elsewhere as long as their food supply (dead skin cells) is present, and they have a moist and warm environment. Spores can live for as long as 12 to 20 months in the right environment.
Which food avoid in fungal infection?
Therefore, anti-fungal diets eliminate:
- Added sugars (examples: cane sugar, honey, syrup)
- Natural sugars (examples: fresh and dried fruit, fruit juice)
- Refined starches (examples: white bread, pastries)
- Starchy vegetables (examples: potatoes, carrots, peas, beans)
Are dermatophytes serious?
Dermatophytes are keratinophilic fungi responsible for benign and common forms of infection worldwide. However, they can lead to rare and severe diseases in immunocompromised patients. Severe forms include extensive and/or invasive dermatophytosis, i.e., deep dermatophytosis and Majocchi’s granuloma.
What does piedra look like?

In otherwise healthy individuals, most dermatophyte infections are not considered serious. Mild forms of localized dermatophyte infections of the skin can be treated with topical antifungals, such as clotrimazole.
Is banana good for fungal infection?
