Genome Sequences of 18 Salmonella enterica Serotype Hadar Strains Collected from Patients in the United States

Despite being linked to a number of recent poultry-associated outbreaks in the United States, few reference genomes are available for Salmonella enterica serotype Hadar. Here, we address this need by reporting 18 Salmonella Hadar genomes from samples collected from patients in the United States between 2014 and 2020

Crosstalk Between Type VI Secretion System and Mobile Genetic Elements

© 2019 Peñil-Celis and Garcillán-Barcia.Many bacterial processes require cell-cell contacts. Such are the cases of bacterial conjugation, one of the main horizontal gene transfer mechanisms that physically spreads DNA, and the type VI secretion systems (T6SSs), which deploy antibacterial activity. Bacteria depend on conjugation to adapt to changing environments, while T6SS killing activity could pose a threat to mating partners. Here we review the experimental evidences of overlapping and interaction between the T6SSs, bacterial conjugation, and conjugative genetic elements.This work was supported by Consejo Superior de Investigaciones Científicas (201820I143 to MG-B).

Mapa plasmídico de Salmonella enterica

Trabajo presentado en el XXVIII Congreso de la Sociedad Española de Microbiología, celebrado en modalidad virtual del 28 de junio al 02 de julio de 2021.Los genes de resistencia a los antibióticos se propagan rápidamente por transferencia genética horizontal, principalmente transportados por plásmidos. De hecho, los plásmidos parecen ser los actores más importantes en la evolución a corto plazo de patógenos bacterianos, como se ejemplifica en las enterobacterias. Por lo tanto, razonamos que será relevante identificar cuál es la importancia relativa de diferentes unidades taxonómicas plasmídicas (PTUs) en la diseminación de genes de resistencia a antibióticos en microorganismos patógenos. A través de una combinación de genómica funcional y metadatos asociados a los plásmidos, ofrecemos un diagnóstico de los plásmidos más relevantes en la diseminación de genes de virulencia y resistencia a antibióticos en Salmonella enterica, así como información sobre la ecología de los brotes multirresistentes

Five Complete Salmonella enterica Serotype Reading Genomes Recovered from Patients in the United States

Between 2018 and 2019, Salmonella enterica serotype Reading caused a large, multistate outbreak linked to contact with raw turkey products in the United States. Here, we provide five Salmonella Reading reference genomes collected from US patients between 2016 and 2018.ACKNOWLEDGMENTS: We would like to acknowledge the state and local public health laboratories that participated in the National Antimicrobial Resistance Monitoring System (NARMS) and PulseNet.
