Item Cryptococcus bacillisporus (VGIII) Meningoencephalitis Acquired in Santa Cruz, Bolivia(2021) Thompson, Luis; Porte, Lorena; Díaz, Violeta; Díaz, María; Solar, Sebastián; Valenzuela, Pablo; Norley, Nicole; Pires, Yumai; Carreño, Fernando; Valenzuela, Sergio; Shabani, Rukmane; Rickerts, Volker; Weitzel, ThomasWe describe a case of chronic meningoencephalitis with hydrocephalus caused by Cryptococcus bacillisporus (VGIII) in an immunocompetent patient from Santa Cruz, Bolivia. This first report of a member of the Cryptococcus gattii species complex from Bolivia suggests that C. bacillisporus (VGIII) is present in this tropical region of the country and complements our epidemiological and clinical knowledge of this group of emerging fungal pathogens in South America.Item Laboratory exposure to Coccidioides: lessons learnt in a non-endemic country(Elsevier Ltd, 2019-08) Porte, Lorena; Valdivieso, Francisca; Wilmes, Dunja; Thompson, Luis; Munita, José; Varela, Carmen; Rickerts, Volker; Weitzel, Thomas; Gaete, P; Díaz, MC; Alliende, RCoccidioides is a primary pathogenic fungus, which infects humans through highly infectious arthroconidia, causing substantial morbidity including life-threatening disseminated infections. Due to the low infectious dose, laboratory personnel might become infected during diagnostic procedures. Accordingly, coccidioidomycosis is reported as the most frequent laboratory-acquired systemic mycosis worldwide. This risk is aggravated in non-endemic countries, where the diagnosis may not be suspected. We report on an inadvertent exposure of 44 persons to Coccidioides posadasii in a clinical microbiology laboratory in Chile, the measures of containment after rapid diagnosis with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and the lessons learnt in a non-endemic setting.
