Salmonella enterica serovar Typhi variants in long-term carriers

J Clin Microbiol. 2013 Feb;51(2):669-72. doi: 10.1128/JCM.02726-12. Epub 2012 Dec 12.

Abstract

Long-term typhoid carriers can simultaneously excrete Salmonella enterica serovar Typhi variants with considerable genetic differences, a situation that complicates the interpretation of the subtyping data used in outbreak investigations and disease surveillance.
