Abstract:
126 multiply resistant S.typhi isolates were screened among 363 isolates collected from Northern, Central and Southern regions of Vietnam during the period 1995-1997. Transfer experiments of the resistance to E.coli K12-J53 from these S.typhi isolates were performed to determine their transferable capacity of resistance factors and its frequency. The results indicated that 74.78% of multiply resistant S.typhi isolates (AM, CL, TE, TR, SU) have R-factors, most of them contained all resistance genes characterizing the resistance of wild strains. The frequency of transfer of the resistance varied from 10-5 to 10-8.
