The objective was to examine effects of treating commercial beef feedlot cattle with therapeutic doses of tulathromycin, a macrolide antimicrobial drug, on changes in the fecal resistome and microbiome using shotgun metagenomic sequencing. Two pens of cattle were used, with all cattle in one pen receiving metaphylaxis treatment (800 mg subcutaneous tulathromycin) at arrival to the feedlot, and all cattle in the other pen remaining unexposed to parenteral antibiotics throughout the study period. Fecal samples were collected from 15 selected cattle in each group just prior to treatment (Day 1), and again 11 days later (Day 11). Shotgun sequencing was performed on isolated metagenomic DNA, and reads were aligned to a resistance and a taxonomic database to identify alignments to antimicrobial resistance (AMR) gene accessions and microbiome content. Overall, we identified AMR genes accessions encompassing 9 classes of AMR drugs and encoding 24 unique AMR mechanisms. Statistical analysis was used to identify differences in the resistome and microbiome between the untreated and treated groups at both timepoints, as well as over time. Based on composition and ordination analyses, the resistome and microbiome were not significantly different between the two groups on Day 1 or on Day 11. However, both the resistome and microbiome changed significantly between these two sampling dates. These results indicate that the transition into the feedlot?and associated changes in diet, geography, conspecific exposure, and environment?may exert a greater influence over the fecal resistome and microbiome of feedlot cattle than common metaphylactic antimicrobial drug treatment.

Potato is considered a staple food in the world and its production is limited by the presence of bacterial wilt (BW) disease caused by Ralstonia solanacearum. Host resistance is the most sustainable and cost-effective strategy to manage BW, although resistant commercial potato cultivars are not yet available. Our group incorporated the EFR receptor of Arabidopsis thaliana(AtEFR), which recognizes the elongation factor Tu, preserved in bacteria, triggering an immune response. AtEFR was tested in two genetic backgrounds: a susceptible commercial cultivar (INIA Iporá) and a breeding clone with partial resistance introgressed from Solanum commersonii. In this work, the effect of the AtEFR receptor on BW resistance was evaluated for the first time, using conditions resembling natural field infection. In addition, the colonization patterns of wild-type and transgenic lines were compared by using luminescent and fluorescent R. solanacearum reporter strains. Both approaches showed a delay and a decrease in the severity of wilting symptoms in the AtEFR-transformed genotypes. Differential colonization pat-terns were observed, revealing a higher bacterial development in the non-transformed plants. ThisAtEFR effect seems more pronounced in the interspecific breeding line, possibly leading to a more effective activation of the plant immune system. |
