Salmonella pathogenicity Island 1 undergoes decay in serovars adapted to swine and poultry by Martina Tambassi, Melissa Berni, Chiara Bracchi, Ilaria Menozzi, Alessandra Dodi, Laura Mazzera, Marina Morganti, Erika Scaltriti, Stefano Pongolini

“…Derby carrying mutated SPI-1 had been previously demonstrated, we showed the same phenotype for mutated S. Rissen. Considering also the known attenuation of S. Kentucky, our population-scale findings provide evidence of progressive evolution toward the attenuation of serovars adapted to the main animal reservoirs of human salmonellosis through the food chain. …”

Small RNA CjNC110 regulates the activated methyl cycle to enable optimal chicken colonization by Campylobacter jejuni by Brandon Ruddell, Alan Hassall, Orhan Sahin, Paul J. Plummer, Qijing Zhang, Amanda J. Kreuder

“…As a growing body of evidence suggests that maintenance of L-met homeostasis appears to be critical for C. jejuni colonization, interventions targeting the AMC could provide a critical control point for therapeutic drug options to combat this zoonotic pathogen. Our results also indicate that even for conserved sRNAs such as CjNC110, strain-specific differences in phenotypes regulated by sRNAs may exist, independent of conserved regulatory action. …”
