Salmonella typhi, is estimated to cause 21.6 million illnesses and 216,000 deaths. The plight of displaced persons has in recent times become a formidable problem of global significance and implication. This work was aimed at isolating and characterizing S. typhi from two internally displaced camps in Jos, Plateau State, Nigeria. A total of 183 stool samples were collected randomly and cultured. Isolates were serotyped and identified by PCR targeting the invasive gene. An antimicrobial susceptibility test was carried out on isolates using the disc diffusion method. The study showed a prevalence of 1.1% for S. typhi and 1.6% for non-typhoid Salmonella. All the isolates were sensitive to ciprofloxacin, ofloxacin ceftriaxone, chloramphenicol and gentamicin except for nalidixic acid and cefuroxime. The Salmonella typhi isolates were sequenced using Fastp for quality control and the genotype was determined. Comparative genomics on the two S. typhi assembled showed S. typhi 1(SO1) contains 38 contigs and S. typhi 2 (SO2) had 35 contigs. The result shows that the genome is similar to the reference strain CT18. More care and adequate health facilities should be provided in other to further reduce the rate of infection in the IDP camps.
