Abstract

SUMMARY

Of 422 clinical strains of , 23 (5.5%) were resistant to gentamicin; 19 were also resistant to tobramycin and sisomycin, and one was resistant to to bramycin, sisomycin and amikacin. Of the gentamicin-resistant strains, 20 were also resistant to kanamycin. Sixteen strains with a high level of resistance to gentamicin (MIC > 160 g/ml) transferred all their resistance determinants to recipient strains of and four transferred some resistance determinants to but none transferred resistance to a recipient strain of K12. These results show that gentamicin resistance in strains of isolated in Auckland is mediated by R plasmids.
