Microsporum distortum is a zoophilic dermatophyte that rarely infects humans. It has been isolated from ringworm in dogs, cats, horses, swine, guinea pigs, monkeys, rabbits, and humans (4,6). It produces a yellow-greenish fluorescence in hair, where it is associated with small ectothrix spores.
Also Is Microsporum a dermatophyte?
Microsporum canis is a zoophilic dermatophyte of worldwide distribution and is a frequent cause of ringworm in humans, especially children. Invades hair, skin and rarely nails. Cats and dogs are the main sources of infection.
Subsequently, Which disease is caused by Microsporum? Tinea corporis (B35. 6) caused by Microsporum canis which is fungal species that causes numerous forms of disease. It is part of a group of fungi known as Dermatophytes. Though mostly well known for ringworm in pets, it is also known to infect humans.
Where does Microsporum canis reproduce in the body? canis mainly causes dermatophytosis in cats and dogs. And infected animals and asexual spores contaminated objects are common sources for human infection. Spores are very resistant, attach to the skin and germinate producing hyphae, which will then grow in the dead, superficial layers of the skin, hair or nails.
What animals are affected by Microsporum canis?
The natural reservoir of Microsporum canis is in cats and dogs. The main reservoir for Microsporum canis are cats and dogs; however, it can also be transmitted to humans through direct and indirect contact with animals and fomites such as combs, brushes, hats, furniture, linens etc.
What type of fungi is Dermatophyte?
Dermatophyte fungi are the ringworm fungi (tinea). They depend on their host, which may be an animal (“zoophilic”) or a human (“anthropophilic”) and need to spread from one host to another to survive. Dermatophytes may also prefer to live in the soil (“geophilic”).
What are the types of dermatophytes?
There are three genera of dermatophytes, Trichophyton, Microsporum, and Epidermophyton.
What are dermatophytes give two examples?
1.1 Tinea pedis or athlete’s foot. 1.2 Tinea cruris or jock itch. 1.3 Tinea corporis or ringworm of the body. 1.4 Tinea faciei or facial ringworm.
What causes microsporum canis infection?
Microsporum canis is among the most common dermatophytes associated with tinea capitis and tinea corporis. Unlike some dermatophyte species, M. canis typically does not cause large epidemics. Humans become infected as a result of direct or indirect contact with infected pets.
What is ringworm caused by?
Ringworm is a common skin infection that is caused by a fungus. It’s called “ringworm” because it can cause a circular rash (shaped like a ring) that is usually red and itchy. Anyone can get ringworm.
What is Dadri disease?
Tinea versicolor is a fungal infection that causes small patches of discolored spots on your skin. It’s also called pityriasis versicolor. It results from a type of yeast that naturally lives on your skin. When the yeast grows out of control, the skin disease, which appears as a rash, is the result.
How does Microsporum reproduce?
Microscopic morphology
Microsporum canis reproduces asexually by forming macroconidia that are asymmetrical, spherically shaped and have cell walls that are thick and coarsely roughened. The interior portion of each macroconidium is typically divided into six or more compartments separated by broad cross-walls.
What does Microsporum canis need to grow?
No special growth factor is required to grow Microsporum canis. No change in pH is observed following inoculation onto BCP-milk-solids-glucose agar. Its teleomorph is called Arthroderma otae. Microsporum canis differs from Microsporum audouinii by perforating hair and growing on polished rice grains.
Where does Microsporum canis come from?
Microsporum canis belongs to the group of dermatophyte fungi, which are closely related organisms that have the ability to invade the stratum corneum of the epidermis and keratinized tissues derived from it, such as skin, nails, and hair of humans and animals.
How does Microsporum canis affect animals?
Trichophyton mentagrophytes and Microsporum canis can affect rabbits, causing circular, crusty, erythematous, alopecic areas that are pruritic. Lesions are usually found on areas that are frequently groomed, such as the base of the ears and muzzle, but can spread to other areas of the body such as the paws.
Can Microsporum canis spread from human to human?
Microsporum canis is a dermatophyte fungus of which cats and dogs are recognized as the natural hosts. M. canis is also easily transmitted to humans, causing lesions to the glabrous skin (tinea corporis) and to the head (tinea capitis).
How does Microsporum canis reproduce in animals?
Microscopic morphology
Microsporum canis reproduces asexually by forming macroconidia that are asymmetrical, spherically shaped and have cell walls that are thick and coarsely roughened. The interior portion of each macroconidium is typically divided into six or more compartments separated by broad cross-walls.
Are dermatophytes filamentous fungi?
Dermatophytes are a closely related homogeneous clade of keratinophilic filamentous fungi3–6 and are associated with the stratum corneum of the skin, as well as hair and nails on the living host.
Are dermatophytes dimorphic fungi?
The dimorphic species (Onygenaceae) were significantly separated from dermatophytes (Arthrodermataceae) and from a third group including geophilic or very weakly pathogenic species (Onygenaceae and Gymnoascaceae).
Which fungi causes Dermatophytosis?
Anthropophilic dermatophytes, such as Trichophyton rubrum and Trichophyton tonsurans, are the main cause of human dermatophytosis. They are often transmitted from one person to another or by contaminated objects (e.g. clothes, hats, hairbrushes), and generally cause long-lasting infection with mild inflammation.
What are the most common dermatophytes?

, the most common dermatophytosis in children, is an infection of the scalp and hair shafts.
…

- Tinea Cruris.
- Tinea Pedis.
What is a type of Dermatophytosis?
Ringworm is a common infection of the skin and nails that is caused by fungus. The infection is called “ringworm” because it can cause an itchy, red, circular rash. Ringworm is also called “tinea” or “dermatophytosis.” The different types of ringworm are usually named for the location of the infection on the body.
What are the example of Dermatophytosis?
2.1 Dermatophytosis
| Tinea infection | Body parts infected |
|---|---|
| Tinea manuum | Hands (palms and flexoral parts of fingers) |
| Tinea corporis | Trunk and extremities |
| Tinea inguinalis | Inguinal fold or groin (genitals) |
| Tinea pedis | Soles |
