Cronobacter sakazakii is a well-known opportunistic pathogen responsible for necrotizing enterocolitis, meningitis and septicaemia in the premature, immunocompromised infants and neonates. This pathogen possesses various virulence factors and regulatory systems, and pmrA/pmrB regulatory system has been identified in a variety of bacterial species. The current study aims to investigate role of pmrA gene in the pathogenicity and virulence characteristics of Cronobacter sakazakii using whole genome sequencing and RNA-seq. Results demonstrated that the absence of pmrA has the potential to affect Cronobacter sakazakii on its pathogenicity, virulence and resistance abilities by regulating expression of numerous related genes, including CusB, CusC, CusR and ESA_pESA3p05434.
