Y. Hashimoto et al., DEVELOPMENT OF NESTED PCR BASED ON THE VIAB SEQUENCE TO DETECT SALMONELLA-TYPHI, Journal of clinical microbiology, 33(3), 1995, pp. 775-777
For a rapid diagnosis of typhoid fever, we developed a nested PCR base
d on the nucleotide sequence encoding the Vi antigen. All Salmonella t
yphi strains along with a Salmonella paratyphi C strain were PCR posit
ive. This assay was able to detect S. typhi at the single-cell level.
