Genomic investigation and nationwide tracking of pediatric invasive nontyphoidal Salmonella in China.

ABSTRACT: Invasive nontyphoidal Salmonella (iNTS) causes significant concern with ~15% morbidity, affecting populations mainly in African countries. However, iNTS infections among the Chinese pediatric population remain largely unknown. Here, we conducted a genomic investigation to study pediatric iNTS infections in a Chinese hospital. iNTS isolates accounted for 15.2% (18/119) of all nontyphoidal Salmonella (NTS) strains. Compared to non-iNTS isolates, iNTS isolates harbored a lower prevalence of antimicrobial-resistant genes of fluoroquinolones and β-lactams, as well as disinfectant determinants and plasmids, but carried a significantly higher prevalence of cdtB, faeCDE, and tcpC genes. Importantly, we detected an emerging serovar Goldcoast as the predominant iNT
