Merit of mobilization technique in transfer of non-autotransferable R-plasmids.
A total of 200 urinary isolates of Esch.coli received at National Salmonella and Escherichia Centre, Central Research Institute, Kasauli during the years 1995 to 1997 were studied for transferable drug resistance. Out of 188 strains, 134 strains showing resistance to either Nalidixic acid or Rifampicin were subjected to autotransferable resistance studies. Of these 134 strains 131 showed either partial or enbloc transfer of R-factor. Mobilization experiment successfully transferred resistance marker in 14 of the 68 isolates in which resistance to one or more drugs could not be transferred during conjugation experiment.
