“…Other animals related to S. schenckii transmission are parrots, rodents, cats, dogs, squirrels, horses, and birds (126,212). Moreover, S. schenckii was also isolated from aquatic animals, primarily fish and dolphins (91,164), as well as from insects that had been in direct contact with the fungus (126). Some authors have reported sporotrichosis cases due to mosquito bites (129).…”

SUMMARY Sporotrichosis, which is caused by the dimorphic fungus Sporothrix schenckii , is currently distributed throughout the world, especially in tropical and subtropical zones. Infection generally occurs by traumatic inoculation of soil, plants, and organic matter contaminated with the fungus. Certain leisure and occupational activities, such as floriculture, agriculture, mining, and wood exploitation, are traditionally associated with the mycosis. Zoonotic transmission has been described in isolated cases or in small outbreaks. Since the end of the 1990s there has been an epidemic of sporotrichosis associated with transmission by cats in Rio de Janeiro, Brazil. More than 2,000 human cases and 3,000 animal cases have been reported. In humans, the lesions are usually restricted to the skin, subcutaneous cellular tissue, and adjacent lymphatic vessels. In cats, the disease can evolve with severe clinical manifestations and frequent systemic involvement. The gold standard for sporotrichosis diagnosis is culture. However, serological, histopathological, and molecular approaches have been recently adopted as auxiliary tools for the diagnosis of this mycotic infection. The first-choice treatment for both humans and cats is itraconazole.

“…An inhalation leading to primary pulmonary infection is quite common in endemic areas [5]. Recently evidence has been growing that infection can also be acquired from animals (cats, armadillos, fish) [3,6,7]. Atraumatic conjunctival sporotrichosis has been reported [8].…”

Infection by a Dimorphic Fungus Sporothrix schenckii in an Immunocompromised Patient

et al. 2005

Infections caused by dimorphic fungi, rarely observed in a temperate climate, may cause chronic infections in immunocompromised patients. We describe a case of sporotrichosis in a 50-year-old woman, who underwent mastectomy due to breast carcinoma, followed by radiation and chemotherapy. She developed skin lesions, localized along the lymphatics. Discharge samples repeatedly yielded a characteristic growth of the dimorphic fungus Sporothrix schenckii. The isolate was resistant to all commonly used antifungal agents, except for itraconazole. Therapy with this antifungal agent resulted in disappearance of the clinical symptoms.

“…As estruturas traumatizantes de alguns peixes fluviais apresentam fungos patogênicos e esta pode ser uma importante via de infecção que deve ser considerada em algumas regiões do Brasil, uma vez que há um grande número de pescadores e peixes traumatogênicos. 6 and more recently in Brazil 7,8 . The incidence of accidents in river fishermen appears to be high, as observed in retrospective and prospective studies 9 .…”

“…Considering the cases of sporotrichosis reported by one of the authors 7,8 , this work aimed to verify the existence of S. schenkii and other potentially pathogenic fungi in traumatogenic structures (stings, rays of fins and sharp teeth) of fish cited as the most hazardous by local fishermen and documented as such in previous publications 9 .…”

“…Phoma belongs to the group of phaeohyphomycosis Due the fact that this research was original, certain difficulties were experienced when identifying the fungi, even with positive cultures from various yeasts and the inclusion of CHORMagar-Candida to analyze the colonies, the molecular methods were very important steps in helping to identify the microorganisms. While the association between sporotrichosis and trauma caused by fish has strong supporting evidence [7][8][9] , the search for S. schenkii was unsuccessfully. However, the identification of fungi of the Phoma genus reveals the pathogenic potential of this infection route: this microorganism is still poorly known in medical circles, even though several reports exists of human illness associated with this fungus 11-14 , especially when iatrogenic states or immunosuppression is also present, or pathological states, such as AIDS and heterologous transplants.…”

Introduction: Fungal infections in human skin, such as sporotrichosis, can occur after fish induced trauma. This work aimed to identify fungi in freshwater fish that are pathogenic to humans. Methods: Extraction of dental arches from Serrassalmus maculatus (piranha) and Hoplias malabaricus (wolf fish), stings from Pimelodus maculatus (mandis catfish), dorsal fin rays from Plagioscion spp. (corvina) and Tilapia spp., for culture in Mycosel agar. Some cultures were submitted to DNA extraction for molecular identification by sequencing ITS-5.8S rDNA. Results: Cultures identified most yeast as Candida spp., while sequencing also permitted the identification of Phoma spp. and Yarrowia lipolytica. Conclusions: While the search for S. schenckii was negative, the presence of fungus of the genera Phoma and Candida revealed the pathogenic potential of this infection route. The genus Phoma is involved in certain forms of phaeohyphomycosis, a subcutaneous mycosis caused by dematiaceous fungi, with reports of infections in human organs and systems. Traumatizing structures of some freshwater fish present pathogenic fungi and this may be an important infection route that must be considered in some regions of Brazil, since there are a large number of a fisherman in constant contact with traumatogenic fish.
