Mixed infection by Histoplasma capsulatum isolates with different mating types ...
Damasceno, Lisandra Serra; Vite-Garín, Tania; Ramírez, José Antonio; Rodríguez-Arellanes, Gabriela; Almeida, Marcos Abreu de; Muniz, Mauro de MedeirosMixed infection by Histoplasma capsulatum isolates with different mating types, in AIDS‑patients are described in this study. Morphological, mating type-specific PCR assay and multilocus sequencing type analysis of H. capsulatum isolates recovered from two Brazilian AIDS‑patients were performed. Five H. capsulatum isolates were recovered at different times from the two patients. Three isolates were obtained fro...

Preheating of urine improves the specificity of urinary cryptococcal antigen te...
Brito-Santos, Fábio; Ferreira, Marcela de Faria; Trilles, Luciana; Muniz, Mauro de Medeiros; Santos, Valdiléa Gonçalves Veloso dosA delay in laboratory diagnosis is related to sequelae and death. Thus, early diagnosis is the key to decrease the high lethality rate due to cryptococcosis. The cryptococcal antigen lateral flow assay (CrAg LFA) Immy test is standardized for a fast screening point-of-care test for cryptococcosis, detecting cryptococcal antigen in serum and cerebrospinal fluid (CSF). Urine screening would be ideal as a noninvas...
Different scenarios for Candida parapsilosis fungaemia reveal high numbers of m...
Barbedo, Leonardo Silva; Vaz, Catarina; Pais, Célia; Galdino Figueiredo-Carvalho, Maria Helena; Muniz, Mauro de Medeiros; Zancope-Oliveira, Rosely MariaNosocomial fungal bloodstream infections (BSI) are increasing significantly in hospitalized patients and Candida parapsilosis has emerged as an important pathogen responsible for numerous outbreaks. The objective of this study was to evaluate C. parapsilosis sensu lato infection scenarios, regarding species distribution and strain relatedness. One hundred isolates of C. parapsilosis sensu lato derived from bloo...
Chronic disseminated histoplasmosis with lesions restricted to the mouth: case ...
Valle, Antonio Carlos F. do; Moreira, Luiz Carlos; Almeida-Paes, Rodrigo; Moreira, João S.; Pizzini, Cláudia V.; Muniz, Mauro de MedeirosWe report a rare case of chronic disseminated histoplasmosis with several ulcerated lesions in the oral cavity in an alcoholic patient without human immunodeficiency virus infection, with no detectable signs and symptoms of systemic disease or extraoral manifestations. Histopathological analysis revealed chronic inflammatory process with granulomas containing Histoplasma-like organisms. The isolation of Histopl...
Erythema nodosum: prospective study of 32 cases
Fernandes, Nurimar C.; Maceira, Juan; Muniz, Mauro de MedeirosThe results of 32 cases studied lead us to the conclusion that erythema nodosum's investigation routine is very important, once in our retrospective study, the percentage of cases of unknown etiology was 69.4%, and in this prospective study it is 21.8%. In 10 cases (31.2%), more than one causing agent was suspected. Infections (bacterial, helminthic, fungal, by protozoa) were diagnosed in 26 cases, streptococca...
