What is microsporum Canis?

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. This fact makes this pathogen both anthrophilic and zoophilic in nature.

What is Microsporum Trichophyton?

Cutaneous Infections About 20 species in three genera – Epidermophyton, Microsporum, Trichophyton – all with the ability to utilise keratin, grow in the non-living tissues of hair, nails, and skin, in the region above the layers where keratin is deposited.

What causes microsporum Canis?

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 kills microsporum Canis?

Bleach is the most widely available and commonly used disinfectant with reasonable efficacy against M. canis, although it can be irritating to the skin and mucous membranes.

What are the microscopic features of Trichophyton mentagrophytes?

The most consistent microscopic feature is the production of large numbers of microaleuriospores in grapelike clusters, especially in the zoophilic strains. Trichophyton mentagrophytes and Microsporum canis can affect rabbits, causing circular, crusty, erythematous, alopecic areas that are pruritic.

What does Microsporum canis do to a rabbit?

Dermatophyte infection, usually Trichophyton mentagrophytes and Microsporum canis, can affect rabbits, causing circular, crusty, erythematous, alopecic areas that are pruritic. Lesions are usually found on the ears and face.

What kind of hair invasion does t.mentagrophytes have?

Hair invasion by T. mentagrophytes is usually small-spored ectothrix and without fluorescence, but some strains may be endothrix with a dull fluorescence. The latter (var. quinckeanum) have been implicated in mouse favus, which produces numerous white crusty lesions throughout the body.

Which is the best treatment for Microsporum canis?

Treatment is similar to that in other species. Topical miconazole, clotrimazole or enilconazole can be used. Concurrent administration with cisapride should be avoided, as there is potential for adverse drug interactions to occur. Griseofulvin is effective at 550 mg/kg once daily but may be teratogenic in breeding does.
