What does Microsporum canis do to the body?
M. 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 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.
How do I get rid of Microsporum canis?
A variety of oral and topical antifungal agents is available and drugs such as griseofulvin (Gri), terbinafine (TER), itraconazole (IT), and fluconazole (FLZ) are used to cure severe infections in humans and animals [2,13,14].
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).
What are the symptoms of Microsporum canis?
Symptoms of ringworm in dogs often include some combination of the following:
- Hair loss (alopecia), which may be patchy or circular.
- Broken hairs and poor hair coat.
- Reddened or ulcerated skin.
- Dandruff (scales)
- Darkened skin.
- Crusting of the skin.
- Itchiness (pruritus) may or may not be present.
What are the symptoms of Microsporum?
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.
Does Microsporum canis fluorescence?
In Microsporum canis infection, scalp hairs emit a diagnostic brilliant green fluorescence.
Does Microsporum canis glow?
Half of the strains of Microsporum canis will glow “apple-green” or “yellow-green” under the lamp. The source of the fluorescence is a metabolite that growing fungi secrete onto the hairs. The Wood’s lamp is a screening tool; it cannot be used to definitively diagnose ringworm.
What test is done to differentiate Microsporum and Trichophyton infection in dogs?
Diagnosis can be confirmed by direct examination of hairs or scales from lesions or by skin biopsy. Dermoscopy or a Wood’s lamp can be used to identify hairs for culture and/or direct examination.
What disease does Microsporum cause?
Approximately 40 different species of fungi can cause ringworm; the scientific names for the types of fungi that cause ringworm are Trichophyton, Microsporum, and Epidermophyton.
How is Microsporum canis transmitted?
Epidemiology of Transmission 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.
Is Microsporum canis ringworm?
Microsporum canis is a 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 and other animals, it is also known to infect humans.
