[Biological disasters and their relation to public health: an analysis of articles published in the State of Paraná, Brazil].

This study emphasizes the relationship between biological disasters and public health through the systematization of the articles produced by institutions of the State of Paraná in the last few decades. These were selected using key words defined in Codar and Cobrade in the Journal Portals of the Capes, Web of Science, Scopus, PubMed, Redulac, Spell, SciELO, Medline and Bireme databases. As a result, 318 articles were located from 1970 onwards, with a peak in 2012.

Morphological and genetic characterization of endophytic bacteria isolated from roots of different maize genotypes.

Maize is one of the most important crops worldwide, and in Brazil, the state of Paraná stands as its largest producer. The crop demands high inputs of N fertilizers, therefore all strategies aiming to optimize the grain production with lower inputs are very relevant. Endophytic bacteria have a high potential to increment maize grain yield by means of input via biological nitrogen fixation and/or plant growth promotion, in this last case increasing the absorption of water and nutrients by the plants.

Molecular and morphological markers for rapid distinction between 2 Colletotrichum species.

Endophytic microorganisms reside asymptomatically within plants and are a source of new bioactive products for use in medicine, agriculture, and industry. Colletotrichum (teleomorph Glomerella) is a fungus widely cited in the literature as a producer of antimicrobial substances. Identification at the species level, however, has been a problem in this type of study.
