Dermatophytosis is a superficial fungal infection of the keratinized tissues, caused mainly by Microsporum canis that occurs more commonly in young cats, less than 1 year old.

Persian cats are predisposed to developing dermatophytosis and the elimination of the infection in this breed seems to be more difficult, requiring longer treatment courses of systemic therapy. Recurrence of the infection chronic dermatophytosis is a very common problem in catteries. Currently, topical treatments are always recommended as adjuvant to systemic therapy and environmental decontamination. There are several treatments and protocols to treat dermatophytosis.

In case of great number of animals, as in catteries or in the presence of generalized infection we always indicate systemic therapy, but sometimes there are problems with collateral effects or cost. Antifungal therapies using griseofulvin, itraconazol, terbinafine are effective and safe. There are also ketoconazole and lufenuron, but the first one can cause collateral effects and the second is not as effective as other treatments.

Pulse therapy dermatofotose in administration of an antifungal drug that have the property of accumulation in keratinized tissues, in periods of one week, followed by a period of suspension of the drug for three weeks. These periods of administration are called pulses and we can use cycles of two or three and sometimes more cycles.


The numbers dermatoritose cycles needed are based on the negative fungal culture. The endpoints of treatment, independent of the drug choice for therapy, are two or three dermaotfitose consecutive fungal cultures obtained at bi-weekly intervals. However emesis was observed in the first week of therapy, and also higher hepatic enzymes serum activities.

Terbinafine had good efficacy and was safe for the treatment of healthy carriers of M. A study in ten healthy cats clinically normal that were administered terbinafine orally at a daily dose of Even after short-term therapy 14 days.

These results suggest that pulse therapy may be very effective for feline dermatophytosis. Cahina fungal cultures were obtained between 42 and 56 days. The owner must observe signs like vomiting, anorexia or jaundice that could indicate liver toxicity and ideally, laboratory monitoring during the antifungal therapy should include at least every month, ALT and FA, mainly in cats that receive prolonged therapies.

Clipping of the hair coat is recommended, but sometimes the owners do not agree with dermatofigose measure. Environmental decontamination has an important role in eradication of dermatophytosis in catteries so it is recommended to use sodium hypochlorite 0.

It is very important that fungal cultures are made before the introduction of new animals in the cattery.

If the topical and systemic therapy including asymptomatic carriers cats is correct done and also the environmental decontamination, we should look for the existence of underlying diseases, mainly feline leukemia or immunodeficiency virus FeLV and FIV.
