Abstract
The sodium arsenate and antibiotic resistance of a total of 750 strains of Enterobacteriaceae andPseudomonas aeruginosa isolated from hospital patients was determined. Resistance to sodium arsenate (minimal inhibitory concentration ≥25 mg/ml) was found in 61.4% of the isolates and was present both in antibiotic-susceptible and antibiotic-resistant strains. Ten enterobacterial isolates (3 sodium arsenate-resistant, antibiotic-susceptible strains and 7 sodium arsenate-resistant, antibiotic-resistant strains) could transfer sodium arsenate resistance to susceptible isolates and toEscherichia coli K-12 by conjugation. From sodium arsenate-and antibioticresistant strains, sodium arsenate and antibiotic resistances were transferred en bloc. Sodium arsenate resistance of antibiotic-susceptible strains was not self-transmissible, and transfer occurred only after R-plasmid mobilization.
