Sporothrix brasiliensisis one of themost virulent zoonosis which affects animals and humans. This fungus is responsible for subcutaneous infection and its contamination is possible through trauma to the skin. Sporotrichosis is highly prevalent in feline. And Rio de Janeiro appears to have the highest occurrence of cases.

Objectives:

This study aims to evaluate the in vitroefficacy of Sporothrix brasiliensisbiotherapic, with and without an association to allopathic medicine commonly used in the treatment.

Methodology:

Conidiumcells of Sporothrix brasiliensiswill be cultured in Potato dextrose agar (PDA) for 5 to 7 days and yeast cells in Brain heart infusion (BHI) for 3 to 5 days. After incubation, the cells will be scraped with a drigalski handle and filtered using cells strainer into a tube and centrifuge for 5 minutes at 3000 RPM. The cells will be resuspended with Phosphate buffered saline (PBS), centrifuge again,and finally resuspended in PBS. After preparing the inocule, the microplates will be prepared. There will be 5groups in vitro. The first one will be the control group, only fungi. The second will be the treatment of fungi with homeopathic medicine (Sporothrix brasiliensis30DH). The third group will be the homeopathic medicine in association with itraconazole. The fourth will be the treatment with itraconazole only. And the last group will be the fungi with dynamized distilled water 30DH. Sporothrix brasiliensis30DHwill be prepared according to Brazilian Homeopathic Pharmacopeia. Results and discussions The experiments are still in progress and the results will be analyzed through Analysis of variance (ANOVA) to determine statistically significant differences. Previous articles based on biotherapic treatments demonstrated successful results, so our research group is conducting these experiments to evaluate the effect in this model.

Conclusion:

Experiments will be made to verify the efficacy of biotherapic on sporotrichosis treatments.
