Dengue is an emerging disease of high impact on human health. Plants are an important source of new antivirals and stands for its biological properties. The aim of this study was to evaluate the cytotoxicity and antiviral activity and elucidate the antiviral mechanism of ethanolic extracts from against dengue virus 2 (DENV-2).

A total of 22 bacterial isolates were obtained and subjected to various biochemical tests, as well as assessments of plant growth-promoting traits such as phosphate solubilization, hydrogen cyanide production, biocontrol properties through antibiosis, and indole acetic production. Genotypic analysis via 16S rRNA gene sequencing and phylogenetic tree construction identified the strains, with one particular strain named SM 33 showing significant growth-promoting effects on seedlings.

This study explored the simultaneous effects of inoculation with GB03 (a PGPR species) and herbivory by third-instar larvae on essential oil (EO) yield and volatile organic compound (VOC) emissions in plants. The density of glandular trichomes was also examined, given that they are linked to EO production and VOC emission.
