Abstract The aim of this work was to know the frequency and geographical distribution of genotypes and mating types of Cryptococcus neoformans and Cryptococcus gattii species complexes isolated from human infections in Argentina during the period from April 2009 to April 2011. A multicenter study was con...
Abstract INTRODUCTION: The average annual incidence of cryptococcosis in Colombia is 0.23 cases per 100,000 inhabitants in the general population, and 1.1 cases per 1000 in inhabitants with Acquired Immune Deficiency Syndrome (AIDS). In addition, the causal fungus has been isolated from the environment,...
Abstract INTRODUCTION: Candida parapsilosis complex species differ from each other with regard to their prevalence and virulence. METHODS: The hydrolytic enzyme activity, biofilm production, and adhesion to epithelial cells were analyzed in 87 C. parapsilosis complex strains. RESULTS: Among the stud...
Introdução: O método clássico para o diagnóstico de micoses é realizado pelo Exame Micológico Direto (EMD) e cultural, que possibilita a visualização de estruturas fúngicas vegetativas e estruturas reprodutivas, respectivamente. Essa combinação é fundamental para reduzir possíveis erros ana...
In patients with invasive fungal infections, the accurate and rapid identification of the genus Candida is of utmost importance since antimycotic sensitivity is closely related to the species. The aim of the present study was to compare the identification results of species of the genus Candida obtained ...
ABSTRACT There are limited data on the molecular epidemiology of cryptococcosis in Brazil. Here, we report on the identification of the molecular pattern of the Cryptococcus species that caused meningitis in patients admitted in a Brazilian reference tertiary care hospital, and review the published studi...

Abstract Background: The yeasts species determination is fundamental not only for an accurate diagnosis but also for establishing a suitable patient treatment. We performed a concordance study of five methodologies for the species identification of oral isolates of Candida in Colombia. Methods: Sixty...
Abstract INTRODUCTION We describe the clinical and laboratorial features of oral candidiasis in 66 HIV-positive patients. METHODS: Polymerase chain reaction-based techniques were performed for differentiation of Candida spp. isolated from patients at a public teaching hospital in Midwest Brazil. RESU...

Abstract In this study, phenotypic methods presented >80% agreement with the molecular identification of 59 Candida parapsilosis complex. Growth at 15% NaCl or pH 7.0 significantly reduced cfu-counts of Candida orthopsilosis, suggesting these conditions may support the development of phenotypic method...
Resumen Introducción. La neurocriptococosis es una infección fúngica oportunista que representa un alto costo en vidas humanas y para la economía de los países. Sus agentes causales, las especies del complejo Cryptococcus neoformans/Cryptococcus gattii, tienen una fase sexuada y otra asexuada, cua...
