Genome degradation in the c-di-GMP signaling pathways and serovar-specific YhjH-YciG interactions rewired motility regulation in Salmonella Paratyphi A

Helit Cohen, Rivka Shem-Tov, Hanan Tawil, Boaz Adani, Heike Bähre, Roland Seifert, Raz Zarivach, Ohad Gal‐Mor

This paper shows how genome degradation in Salmonella Paratyphi A rewires c-di-GMP signaling and motility regulation through pseudogenization of ycgR and a serovar-specific YhjH-YciG interaction.

HilE mediates motility thermoregulation in typhoidal Salmonella serovars at elevated physiological temperatures

Rivka Shem-Tov, Ohad Gal‐Mor

This study shows that HilE represses motility in typhoidal Salmonella at elevated temperatures, unlike nontyphoidal strains, and this thermoregulation affects host interaction.
