The rare < em > Salmonella enterica < /em > serovar Isangi: genomic characterization of the antimicrobial resistance, virulence potential and epidemiology of Brazilian strains in comparison to global isolates
Conclusion. The presence of S. Isangi strains from Brazil and different countries showing a close genomic correlation, antimicrobial resistance profiles to drugs used in human therapy and a large number of virulence determinants reinforced the need for stronger initiatives to monitor rare non-typhoidal Salmonella serovars such as S. Isangi in order to prevent its dissemination among human and non-human sources.PMID:37462464 | DOI:10.1099/jmm.0.001736

Genomic analyses of drug-resistant Salmonella enterica serovar Heidelberg strains isolated from meat and related sources between 2013 and 2017 in the south region of Brazil
In conclusion, the presence of multidrug-resistant S. Heidelberg strains in Brazil showing a global genomic relationship may alert for the necessity of stronger surveillance measures by food safety and public health authorities to limit its spread to humans and animals through foods.PMID:36920496 | DOI:10.1007/s00294-023-01264-4

Development of modified enrichment broth for short enrichment and recovery of filter-injured Salmonella Typhimurium
Int J Food Microbiol. 2021 Dec 4;362:109497. doi: 10.1016/j.ijfoodmicro.2021.109497. Online ahead of print.ABSTRACTThe filter concentration method facilitates the rapid detection of foodborne pathogens. The filter concentration method lowered the limit of detection (LOD) of artificially inoculated cabbage with Salmonella Typhimurium; however, the procedure injured foodborne pathogens during filtering procedure. Thus, to detect injured pathogens under the detection limit, an enrichment broth promoting pathogen resuscitation and growth is required. To rapidly recover, cultivate and lower the time to result (TTR) of S. Typhim...

Rapid identification of magnesium ascorbyl phosphate utilizing phosphatase through a chromogenic change-coupled activity assay
In this study, we report a chromogenic reaction between magnesium ascorbyl phosphate (MAP) and ferric chloride to generate a Brown-Red clathrate, while the Treated MAP by phosphatases forms Colorless (BRTC) product with ferric chloride. The BRTC was indicative of phosphatase activity-mediated excision of phosphorous group from MAP and utilized to screen phosphatases from bacterial cell lysates. From ten tested strains, BRTC was observed in the cell lysate of Salmonella enterica subsp. enterica serovar Cerro 87. BRTC was again employed to track phosphatase activity of the resuspensions of the ammonium sulfate graded precipi...

A Novel lncRNA Regulates the Toll-Like Receptor Signaling Pathway and Related Immune Function by Stabilizing FOS mRNA as a Competitive Endogenous RNA
In conclusion, our study shows that the novel lncRNA- XLOC_098131 plays a key role in the molecular mechanism underlying the immune function mediated by DA. This study provides new insight into the molecular mechanisms through which DA affects the Toll-like receptor signaling pathway-related immune response and the mechanisms through which lncRNAs regulate mRNA expression. As direct target genes, miR-548s plays important roles in mediating the regulation of FOS by the lncRNA- XLOC_098131 to affect immunity. These data constitute high-quality resources for future genome and functional research. Ethics Statement The experi...
