Grain samples from five wheat and five barley cultivars from different locations and planting dates were examined for the presence of Fusarium species. Fusarium graminearum was the primary species associated with FHB (Fusarium head blight). It comprised 76 % and 60 % of all Fusarium species isolated from wheat grains in 2001 and 2002, respectively. Fusarium graminearum represented 65 % and 56 % of all Fusarium species isolated from barley grains in 2001 and 2002, respectively. The frequencies with which Fusarium species other than F. graminearum were recovered varied depending on both environment and host cultivar. Copyright (c) 2022 Agrociencia Uruguay |

Antimicrobial resistance is a growing concern in public health and current research shows an important role for bacterial biofilms in recurrent or chronic infections. New strategies, therefore, are necessary to overcome antimicrobial resistance, through the development of new therapies that could alter or inhibit biofilm formation. In this sense, antibiofilm natural products are very promising. In this work, a bioprospection of antimicrobial and antibiofilm extracts from Uruguayan soil bacteria and insect gut bacteria was carried out. Extracts from extracellular broths were tested for their ability to inhibit planktonic cell growth and biofilm formation. Genomic analysis of Bacillus cereus ILBB55 was carried out. All extracts were able to inhibit the growth of, at least, one microorganism and several extracts showed MICs lower than 500 µg mL?1 against microorganisms of clinical relevance (Staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacter cloacae). Among the extracts evaluated for biofilm inhibition only ILBB55, from B. cereus, was able to inhibit, S. aureus (99%) and P. aeruginosa (62%) biofilms. Genomic analysis of this strain showed gene clusters similar to other clusters that code for known antimicrobial compounds. Our study revealed that extracts from soil bacteria and insect gut bacteria, especially from B. cereus ILBB55, could be potential candidates for drug discovery to treat infectious diseases and inhibit S. aureus and P. aeruginosa biofilms. |
