High-Resolution Single Nucleotide Polymorphism Analysis Distinguishes Recrudescence and Reinfection in Recurrent Invasive Nontyphoidal Salmonella Typhimurium Disease

Abstract

High-resolution whole-genome phylogenetics successfully discriminated recrudescent iNTS from reinfection, despite a high level of clonality within and among individuals, giving insights into pathogenesis and management. These methods also have adequate resolution to investigate the epidemiology and transmission of this important African pathogen.
