multiple drug resistance and genetic characterization of salmonella typhimurium isolated at chandigarh.a total of 1072 strains of s. typhimurium were isolated in chandigarh during 1985-1988. genetic characterization of 'r' plasmids was attempted in 21 multiple drug resistant strains (ackssu tt p-19, ackssu, tp-i, akssu tp-1). all the 21 strains were sensitive to gentamicin, furoxone and nalidixic acid. level of resistance to different antimicrobial drugs varied from 200 to 1000 mg/l. majority of the strains were untypable by the present set of 31 typing phages (ut-17, phage type 21-2, phase type ...19938354548
