Thirty three strains of Pseudomonas aeruginosa isolated from chronic suppurative otitis media were tested for their antibiotic susceptibility against ampicillin (A), chloramphenicol (C), gentamicin (G), kanamycin (K), cephalexin (CeLstreptomycin(St), tetracycline (T), carbenicillin (Ca) and nalidixic acid (Nx). Fourstrains were found to be Carbenicillin resistant. Resistance factor from 6% of total 33 strains of Ps. aeruginosa and 50% of the total 4 carbenicillin resistant strains could be transferred to standard recipient Eseh. eoli K-12 F-Ldc Nx’. Both the transconjugants transferred their acquired resistance pro-. perty to Eseh. eoli K-12 F-Lac-Nxr showing that the resistance was plasmid mediated. Attempts to transfer the R-factor from 6 Ereh. coli…
