Sporothrix schenckii

This study was carried out with financial support of CNPq. The National Academies Vimorfico Infection with Cells from Old Cultures Mouse footpads were monitored over the course of seven months, while animals maintained a stable and chronic infection process. Due to the distinct cytological features of S.

Esterre P, Richard-Blum S. Exame citologico no diagnostico de lesoes da pele e subcutaneo.

Footpad volume was calculated based on height and width measurements dimorflco the mathematical formula for a cylinder volume. In this study, we verified that F. In cats, sporotrichosis causes ulcerative lesions in the head, face, ears, nails, forelimbs and hindlimbs 3. How to cite this article.

Therefore, the present study aims to describe the morphology of F. Services on Demand Journal. Additionally, observed lesions presented microabscesses surrounded by foamy macrophages with polymorphonuclear leukocyte PMN infiltration, and encapsulated by fibroblasts.


Recently, artificial inoculations of C. Based on this study, we identified fungal cells from old cultures capable of provoking chronic chromoblastomycosis under experimental conditions, especially when more than hogno site is infected.

Ketoconazole or itraconazole should be used in those animals that do not tolerate, like dimorrico, or do not respond to iodides 9.

Other Sporothrix species, however, have been reported as agents of sporotrichosis 2.

The fungal hoongo employed in this study was preserved in sterile distilled water inside sealed penicillin tubes by the method of Castellani and maintained at room temperature. A sample of infected tissue was analyzed and cultivated on SDA.

Experimental murine chromomycosis mimicking chronic progressive human disease. We also noted additional pathological characteristics that further indicated the similarity in the disease process between our infected mice and human CBM patients, such as fibrosis, acanthosis and hyperkeratosis.

Separate each e-mail address dimordico a semicolon Subject line: Filtrates were drawn up into a 50 mL glass needle and ejected into a beaker several times to disrupt small mycelia clusters and to obtain solitary cells and small dimofico of hyphae. All animals infected showed progressive inflammatory process of footpads in the early post-infection period Figure 4. According to our histological results, we detected tissue hyperplasia and granulomatous reactions with microabscesses containing central neutrophil infiltrates surrounded by foamy macrophages, sclerotic bodies inside giant cells, rare lymphocytes and eosinophils, and an external layer encapsulated by fibroblasts.

The minimal concentration of the fungal inoculum for animal infection was standardized by a pilot study. In our previous experiments, we observed that inoculation at two sites with day-old forms is sufficient to cause this persistent infection. Mouse footpads were monitored over the course of seven months, while animals maintained a stable and chronic infection process. Its effectiveness was proven in some studies by comparing this technique with histopathologic diagnosis of neoplasia where they found a diagnostic correlation of July 7, Full paper published online: Fungal cells similar to the parasitic forms found in CBM can be induced in vitro under acidic conditions with low calcium concentration Ten minutes prior to infection, animals were intraperitoneally anesthetized with 0.

Interestingly, several fungal forms of F.

Such forms may be precursors of sclerotic cells subsequently observed at seven months after the infection. Cells were then recovered by centrifuging homogenates at g for ten minutes and subsequently observed by optical microscopy. Listen Larger documents may require additional load time.
