Dermatophytest

Detection of dermatophytes via culture on selective medium

Presentation

Advantages

Method: Rapid culture on DTM agar

Analysis: Detection of pathogenic fungi from the genus Microsporum and Trichophyton, via culture on agar medium

Sample: Skin scrape, skin swab, hair, feather

Preparation: 2 minutes

Reading: 2 to 14 days

Storage: 16 months between 2°C and 8°C, 6 months at room temperature
(2°C – 30°C)

Presentations: 6 tests, 18 tests

Reliability: The reference method for the culture of dermatophytes is culture on DTM (Dermatophyte Test Medium) ⁽¹⁾

Easy to use, Dermatophytestenables the culture of dermatophytes in one step, from any type of sample: swab, skin scrape, hair pluck.

Easy to read, Dermatophytest indicates the growth of dermatophytes by a colour change in the gel.

The large opening of Dermatophytestfacilitates the inoculation of the sample and enables easy re-inoculation of colonies for microscopic examination.

Why to use Dermatophytest?
Dermatomycoses are caused by the proliferation of Microsporum and Trichophyton in cats, dogs, rodents or lagomorphs. Dermatomycoses have a significant zoonotic potential.⁽²⁾ The spores which are disseminated by infected animals, colonize keratinized zones (hair follicles, cornified layers, claws), where they form hyphae and generate an inflammatory reaction that may become chronic. Culture is the most reliable method for the detection of dermatophytes ⁽³⁾. Direct examination of hair and Wood's lamp test lack sensitivity.

When to use Dermatophytest?
Dermatophytest is recommended in cases of localized or multifocal alopecia, crusty or squamous dermatosis, to identify the presence of dermatophytes. For secondary infected lesions, Dermatophytest can be used to assess the need for antifungal treatment as well. Dermatophytest can be used to identify asymptomatic or transient mechanical carrier animals to prevent the zoonotic risk for sensitive people ^(4).
