Spenolimycin, a new spectinomycin-type antibiotic. III. Biological properties.

ABSTRACT

Spenolimycin is a new spectinomycin-type antibiotic isolated from Streptomyces gilvospiralis sp. nov. In vitro, it was active against a wide variety of aerobic Gram-positive and Gram-negative bacteria and Neisseria gonorrhoeae. It was two to four-fold more active against N. gonorrhoeae than spectinomycin. Spenolimycin was effective in the standard mouse protection test against Escherichia coli, Klebsiella pneumoniae and Streptococcus pneumoniae.
