Yeasts are potential plant-growth-promoting microbes; however, this resource is underexploited, mainly in the semiarid regions worldwide. In the present study, we isolated potentially endophytic yeasts from roots of fieldgrown maize and characterized them at molecular, biochemical, and associative levels. Thirteen yeasts were retrieved, and the ITS...

A microbiologia é a ciência que estuda os organismos microscópicos, ou seja, aqueles que não são visíveis a olho nu e, portanto, precisam ser examinados com um microscópio sendo, por isso, denominados microrganismos. Incluem-se nesses estudos não apenas a morfologia dos microrganismos, mas também suas atividades metabólicas, suas relações com o amb...
Iron is a micronutrient required by almost all living organisms, including fungi. Although this metal is abundant, its bioavailability is low either in aerobic environments or within mammalian hosts. As a consequence, pathogenic microorganisms evolved high affinity iron acquisition mechanisms which include the production and uptake of siderophores....

Rapid growing mycobacteria (RGM) have important implications in human diseases, being often related to opportunistic infections. Since its description in 2004, clinical cases related to Mycobacterium massiliense, a representative species of the RGM group, have been increasingly reported. With the increase of outbreaks related to these bacteria, the...
The genus Paracoccidioides includes termodimorphic fungal species which causes paracoccidioidomycosis, a systemic mycosis endemic in Latin America. The infection occurs when mycelium propagules or conidia are inhaled by the host. After conversion to yeast in the alveoli the fungus may disseminate to other organs and tissues. Iron is an essential mi...
