S. typhi is causes typhoid in Iraq and developing countries. The abuse of antibiotics make the patient infected with S. typhi wich is resistant to many antibiotics. Aims of the study: Molecular and phylogenetic tree of genomic resistance genes associated Aminoglycoside nucleotidyltransferase (aad-A1), and detection mutation occur in aadA1 gene. Disc diffusion method and VITEK2 compact system to detect the resistance of S.typhi to 11 antibiotics and using the PCR technique to detect the prevalence of aadA1 resistance gene. The genomic DNA extracted from all S. typhi isolated harboring resistance gene. The prevalence of the aadA1 gene was 12(24%) from all S. typhi isolates and the presence of a silent mutation in sample number 2 Iraqi isolate. The first isolate (MW805237.1) was almost just like the isolates of each of the countries Korea, Iran Iran, India, and Madagascar, but The second Iraqi isolate (MW805238.1) was the share of congruence between them at 99% at position G. The aadA1 gene was present in S. typhi isolated from blood, the stool of human, and the detected mutation has no effect.
