Resistance Factor-Mediated Spectinomycin Resistance
AUTOR(ES)
Smith, David H.
RESUMO
Of 100 natural isolates of drug-resistant enteric bacteria, 51 were resistant to spectinomycin (Spc) and 46 contained transferable R factors mediating Spc resistance. All SpcR R factors mediated streptomycin and bluensomycin resistance and were fi+ type. Extracts of R-SpcR strains adenylated Spc, dihydrospectinomycin, actinamine, streptomycin, and bluensomycin in vitro in the presence of adenosine triphosphate and Mg++. Results of genetic and biochemical studies support the hypothesis that these reactions are mediated by a single enzyme.
