Besides, veterinarians should also be aware that health cats may play important role on sporotrichosis epidemiology, since the fungus can be recovered from nails, nasal and oral mucosa of health cats, mainly those who have free access to environment In conclusion, the technique of fine-needle aspiration herein employed is consistent with previous ones described in literature and dimorgico a non-invasive, quick and low cost approach to diagnose feline sporotrichosis.

La esporotricosis es una enfermedad micotica que afecta a los humanos y honog los animales provocada por el hongo dimorfico Sporothrix schenckii.

At 4 to 5 days post-infection, animals developed a small inflammatory response on their footpad. Outbreaks in USA and Australia have been linked to contact with plant material 4.

We also verified that low concentrations of aged inoculum are capable of producing a stable experimental infection, in contrast to other studies that employed a high number of F. Eight mice inoculated at one site healed after five months. Biodiversity of the genus Cladophialophora. The swelling lasted for two months, and it acquired a firm consistency.

Sporothrix schenckii

Evaluation of an epidemic of sporotrichosis in cats: Facultade de Medicina Veterinaria dimrfico Zootecnia http: Cytologic diagnosis and treatment of feline sporotrichosis: The microorganism is a saprophyte which is found in soil and decomposing organic matter 1.

Therefore, the present study aims to describe the morphology of F. Sporotrichosis caused by Sporothrix globosa in Rio de Janeiro, Brazil: Listen Larger documents may require additional load time.

Ketoconazole or itraconazole should be used in those animals that do not tolerate, like cats, or do not respond to iodides 9. Nosanchuck JD, Casadevall A. Guidelines on the care dimotfico use of animals for scientific purposes. This paper describes the cytologic diagnosis by fine-needle aspiration and treatment of a case of feline sporotrichosis.

Feline sporotrichosis has been reported in the literature because of its continuing importance as a source of infections for humans, particularly for veterinarians and animal owners. El diagnostico de esporotricosis puede dimlrfico realizado mediante el examen citologico y histopatologico, aislamiento del hongo, inmunofluorescencia y metodos moleculares.

Effective acute cellular response in animals against F. In this study, however, sclerotic bodies were resistant to neutrophil killing mechanisms and macrophage phagocytosis.

Sporothrix schenckii isolated from domestic cats with and without sporotrichosis in Rio de Janeiro, Brazil. Chromoblastomycosis murine model and in vitro test to evaluate the sensitivity of Fonsecaea pedrosoi to ketoconazole, itraconazole and saperconazole. Mem Inst Oswaldo Cruz.

July 7, Full paper published online: The finding of a great number of yeasts in lesions and exudates is a markedly feature in feline sporotrichosis, while in other species it has been observed few numbers of organism. A variety of cellular forms of the F. The presence of parasitic forms normally known as sclerotic fumagoid or muriform cells also known as Medlar bodies in tissues is dimorffico typical sign of the human form of the disease hlngo, 4.

Seven months after infection, mice were killed and their footpads were removed in accordance with guidelines on the use and care of laboratory animals Tools Related Resources ReadSpeaker:. The microbial ability to synthesize melanins can be related to virulence and pathogenicity Curr Opin Infect Dis.

After five months, several animals that were inoculated in two footpads developed foot hyperkeratosis. Short hyphal fragments had approximately six to ten septa. Its effectiveness was proven in some studies by comparing this technique with histopathologic diagnosis of neoplasia where they found a diagnostic correlation of The minimal concentration of the fungal inoculum for animal infection was standardized by a pilot study.

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. In one group, long-term cultured F. Histopathological sections of tissue from human disease revealed hyperkeratotic pseudoepytheliomatous hyperplasia with microabscesses rich in polymorphonuclear neutrophils 4, At the time of examination, the animal was presenting an ulcerative, erythematous lesion, with serosanguineous exudate, measuring four centimeters in diameter in the right periocular region Figure 1.

Since the diagnosis was performed, the animal started treatment and remission of clinical signs were observed after six honggo, other feature that confirms the etiology dimorfido this case. January 20, Accepted: Rare eosinophils and lymphocytes were found. CBM therapy has produced limited success, especially in severe clinical forms 1, 3. Ascending lymphangitis may arise from the primary wound site but rarely spreads to other organs 1.

July 1, Abstract published online: Such forms may be precursors of sclerotic cells subsequently observed at seven months after the infection. Sections taken from infected tissues in animals inoculated at a single site showed a higher number of neutrophils than those taken from animals inoculated at multiple sites, while several hlngo from the dmorfico infection group healed after five months.
