Tregs in the immune response of BALB/c mice experimentally infected with species of the genus.

Sporotrichosis occurs through contact with contaminated soil and plant. However, the incidence of sporotrichosis as a zoonotic epidemic has increased, particularly in Rio de Janeiro. In this work, we decided to evaluate some T-cell phenotypes involved in the immune response.

Copper overload in Paracoccidioides lutzii results in the accumulation of ergosterol and melanin.

Paracoccidioidomycosis is a highly prevalent systemic mycosis in Latin America, caused by fungi of the genus Paracoccidioides. Copper is essential for eukaryotes and bacteria. This micronutrient is used in many vital biochemical processes, although metal excess levels can be toxic for organisms.

Sporothrix schenckii Sensu Lato identification in fragments of skin lesion cultured in NNN medium for differential diagnosis of cutaneous leishmaniasis.

Eighty-nine patients with clinical suspicion of leishmaniasis were referred for differential diagnosis. Sporothrix schenckii sensu lato was isolated in Novy-MacNeal-Nicolle + Schneider media in 98% of 64 patients with final diagnosis of sporotrichosis. This medium may be suitable for diagnosis of sporotrichosis in areas where cutaneous leishmaniasis is also endemic.
