1. Donor-Derived Transmission of Cryptococcus gattii sensu lato in Kidney Transplant Recipients

Author

Santos, Daniel W C L, Hagen, Ferry, Meis, Jacques F, Cristelli, Marina P, Viana, Laila A, Bernardi, Fabiola D C, Tedesco-Silva, Hélio, Medina-Pestana, José O, Colombo, Arnaldo L, Santos, Daniel W C L, Hagen, Ferry, Meis, Jacques F, Cristelli, Marina P, Viana, Laila A, Bernardi, Fabiola D C, Tedesco-Silva, Hélio, Medina-Pestana, José O, and Colombo, Arnaldo L

Abstract

We describe cases of donor-derived transmission of Cryptococcus deuterogattii in 2 kidney transplant recipients in Brazil and published information on other cases. Prompt reduction of immunosuppression and initiation of antifungal therapy was required to successfully control the fungal infections and preserve engraftment.

5. Fonsecaea pugnacius, a Novel Agent of Disseminated Chromoblastomycosis

Author

de Azevedo, Conceição M P S, Gomes, Renata R, Vicente, Vania A, Santos, Daniel W C L, Marques, Sirlei G, do Nascimento, Mariana M F, Andrade, Caroline E W, Silva, Raimunda R, Queiroz-Telles, Flávio, de Hoog, G Sybren, de Azevedo, Conceição M P S, Gomes, Renata R, Vicente, Vania A, Santos, Daniel W C L, Marques, Sirlei G, do Nascimento, Mariana M F, Andrade, Caroline E W, Silva, Raimunda R, Queiroz-Telles, Flávio, and de Hoog, G Sybren

Abstract

We report a fatal case of a chromoblastomycosis-like infection caused by a novel species of Fonsecaea in a 52-year-old immunocompetent Caucasian male from an area of chromoblastomycosis endemicity in Brazil. The patient had a 30-year history of slowly evolving, verrucous lesions on the right upper arm which gradually affected the entire arm, the left hemifacial area, and the nose. Subsequent dissemination to the brain was observed, which led to death of the patient. The internal transcribed spacer (ITS) and partial large subunit (LSU), BT2, and CDC42 genes of the isolates recovered from skin and brain were sequenced, confirming the novelty of the species. The species is clinically unique in causing brain abscesses secondary to chromoblastomycosis lesions despite the apparent intact immunity of the patient. Histopathologic appearances were very different, showing muriform cells in skin and hyphae in brain.
