Dermatophytes : The test switches to quantitative PCR

Biovet is proud to announce the improvement of its PCR test for dermatophyte detection. Dermatophytes, also commonly known

IMPROVEDBiovet is proud to announce the improvement of its PCR test for dermatophyte detection. Dermatophytes, also commonly known as ringworm, are common fungal agents involved in skin, hair and claw mycoses. The main zoophilic species detected are: Microsporum canis (by far the most common), Trichophyton spp (benhamiae, bullosum, equinum, erinacei, mentagrophytes, quinckeanum, simii, verrucosum) and Nannizzia gypsea (essentially a geophilic species, formerly known as Microsporum gypseum). These three species or species complexes are now detected using a new real-time PCR multiplex (qPCR), more sensitive than regular PCR..

The results will be returned semi-quantitatively (Ct).

Interpretative legend:

Ct Value Interpretation
Ct > 38  Negative
35 < Ct < 38  Suspect
30 < Ct < 35  Weak positive
25 < Ct < 30  Average positive
Ct < 25  Strong positive

Specimen to submit:

We recommend that at least a dozen hairs be submitted (sensitivity apparently increases with the number of hairs submitted) in a tightly sealed sterile container, stored at room temperature or in the refrigerator (to prevent the growth of contaminants).

It is also possible to submit culture media for dermatophytes that have been seeded with hair.

This test will be performed 3 to 4 times a week.
