Studies involving endophytic fungi isolated from endemic plants and their antibacterial potential are largely unknown in the Pampa biome. In this study, we identified endophytic fungi isolated from Kelissa brasiliensis (Iridaceae), an endemic species of the Brazilian Pampa, and assessed their antibacterial activity. Endophytic fungi were first grouped based on macro-and micro-morphology, and one representative of each morphospecies was analyzed using sequences from the internal transcribed spacer (ITS) rDNA region. We then tested the fungal extracts against laboratory isolates of Staphylococcus aureus and Escherichia coli for antibacterial activity. A total of 30 endophytes were isolated from the tissues of K. brasiliensis, with the majority from the leaves. Endophytes were then grouped into seven morphospecies based on their morphological features and one representative from each was selected for phylogenetic analysis. The inference from the ITS rDNA sequences identified the endophytes of the seven selected morphospecies as belonging to six taxonomic groups: Colletotrichum (two), Diaporthe (one), Epicoccum (one), Fusarium (one), and Pestalotiopsis (one). The endophyte extracts revealed better results against E. coli than S. aureus, although the extracts from Colletotrichum and Pestalotiopsis sp. were statistically similar to the control antibiotic. Our study is a basis for endophytic fungi studies in Pampa.
