Introduction Sporotrichosis is a mycosis caused by the dimorphic fungus Sporothrix spp., and the primary mode of transmission is traumatic inoculation of fungus conidia from plants and other organic matter.
Methods Sporotrichosis was established in a cat and in three members of one family from a rural area, by fungal growth in culture.
Results The cutaneous lesions developed on the lower buttock and limbs with no report of any injury.
Conclusion Although sporotrichosis should be considered for differential diagnosis in people working with soil and plants, cases of chronic lesions on skin of cats and in households is probably a new epidemiological approach in a given geographic region.
Sporotrichosis is a widespread subcutaneous mycosis caused by the dimorphic fungi now known as the Sporothrix schenckii complex. This complex is comprised of at least six species, including Sporothrix albicans, Sporothrix brasiliensis, Sporothrix globosa, Sporothrix luriei, Sporothrix mexicana and S. schenckii. Cases of sporotrichosis have significantly increased in Brazil over the past decade, especially in the state of Rio de Janeiro (RJ), where an epidemic among cat owners has been observed. The zoonotic transmission from cats to humans suggests a common source of infection and indicates that animals can act as vectors. We performed a molecular characterisation of samples collected during the first outbreak of familial sporotrichosis caused by S. brasiliensis in the state of Espírito Santo, Brazil. These results represent the first description of such an outbreak outside the endemic area of zoonotic sporotrichosis in RJ.
