Actinobacteria occur in many environments and have the capacity to produce secondary metabolites with antibiotic potential. Identification and taxonomy of actinobacteria that produce antimicrobial substances is essential for the screening of new compounds, and sequencing of the 16S region of ribosomal DNA (rDNA), which is conserved and present in all bacteria, is an important method of identifi...

In the course of a taxonomic revision of Pseudobombax Dugand, one of us (JGCS) frequently has observed herbarium specimens of Bombacoideae that comprise a mixture of different Angiosperm families. In particular, Pseudobombax heteromorphum (Kuntze) A. Robyns, a frequent name in checklists of the Bolivian flora, is based on type material of Bombax heteromorphum Kuntze that is clearly a mixture of...

In October 2012, the CDC reported an outbreak of fungal meningitis associated with methylprednisolone injections [1]. Although the index case had Aspergillus fumigatus meningitis [2], subsequent reports indicated that the majority of affected patients had meningitis caused by Exserohilum rostratum, an extremely rare cause of human fungal disease [1,3,4]. The outbreak is presumably the result of...

Harmful algal blooms (HABs) are becoming widely distributed and more frequent, threatening socioecosystems human health. We determined species composition, abundance spatial distribution of dinoflagellate cysts in the upper sediment Oualidia Lagoon located on Atlantic coast Morocco. Sediment samples were collected 2017 at 51 stations, environmental parameters measured together with microphytopl...

Two species of microcolonial fungi - Cryomyces antarcticus and Knufia perforans - and a species of black yeasts-Exophiala jeanselmei - were exposed to thermo-physical Mars-like conditions in the simulation chamber of the German Aerospace Center. In this study the alterations at the protein expression level from various fungi species under Mars-like conditions were analyzed for the first time us...
