Spectinomycin is an aminocyclitol antibiotic that acts by binding to the
30S subunit of the bacterial ribosome and inhibiting protein synthesis. Its
activity is generally modest, particularly against gram-positive bacteria.
Some gram-negative bacteria are sensitive. Resistance in vitro may develop
by chromosomal mutation or may be plasmid located.
