Abstract: Clinical salmonellosis has been increasing significantly in Brazil in recent years. A total of 130 outbreaks distributed among 10 swine-producing states were investigated. One representative Salmonella isolate from each outbreak was characterized through serotyping, antimicrobial resistance profiles, PFGE, and WGS. From 130 outbreaks: 50 were enteric, 48 were septicemic, 17 cases were characterized as hepato-biliary invasive, 13 as nodal and two were not classified. The most prevalent serovars were a monophasic variant of S. typhimurium (55/130), Choleraesuis (46/130), and Typhimurium (14/130). Most of the strains (86.92%) demonstrated a high rate of multi-drug resistance. The identification of a major Choleraesuis clonal group in several Brazilian states sharing the same resistance genes suggested that these strains were closely related. Six strains from this clonal group were sequenced, revealing the same ST-145 and 11 to 47 different SNPs. The detected plasmid type showed multiple marker genes as RepA_1_pKPC-CAV1321, the first to be reported in Salmonella. All AMR genes detected in the genomes were likely present on plasmids, and their phenotype was related to genotypic resistance genes. These findings reveal that salmonellosis is endemic in the most important pig-producing states in Brazil, emphasizing the need to make data available to aid in reducing its occurrence. |

Membrane technologies have been considered as an efficient and economical alternative to help providing clean water for the population on a large scale. In this regard, the development of low-cost adsorbent membranes, with scalable production and high efficiency is indeed necessary and urgently required. In this work, we investigated the methylene blue removal performance of solution blow spun (SBS) polyamide 6 (PA6) nanofibrous membranes (NFMs) coated with different types of carbonaceous materials. Sucrose was employed as carbon source and two distinct approaches, namely hydrothermal and caramelization routes, were investigated to produce it. The NFMs were functionalized by dip-coating and then chemically activated using NaOH to further enhance the adsorption efficiency. The carbonaceous materials-modified NFMs were characterized by scanning electron microscopy (SEM), contact angle, Zeta potential, Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). Batch and fixed bed experiments revealed that the NFMs modified by dip coating with the carbonaceous materials present competitive adsorption capacity in addition to be a simple, low cost and scalable strategy. The experimental and maximum adsorption capacities of batch adsorption were 371.69 mg/g and 471.58 mg/g for the NFMs modified with hydrothermal carbon, and 260.52 mg/g and 651.04 mg/g for the NFMs coated with black caramel, respectively. The NFMs modified with hydrothermal carbon and caramel carbon showed applicability in scalable systems based on fixed bed adsorption experiments. Our results suggest that nanofibrous membranes coated with carbonaceous materials from sucrose are a suitable tool to develop adsorptive membranes for pollutants removal and open the venue to also explore other carbon-rich sources, including bio- and food residues for adsorptive applications.
