Clear zones of suppression of bacterial growth around the individual antibiotic disks are evidence of sensitivity to these antibiotics. In veterinary medicine, streptomycin is the first-line antibiotic for use against gram negative bacteria in large animals ( horses, cattle, sheep, etc.). It is commonly combined with procaine penicillin for intramuscular injection. [medical citation needed] Tularemia infections have been treated mostly with streptomycin.

Streptomycin inhibits prokaryote protein synthesis. Tetracycline (2.0 μg/ml) decreased the number of positive L-form cultures at about the same rate as combinations of the higher concentrations of penicillin and streptomycin. Various concentrations of tetracycline (0.1 to 2.0 μg/ml) with 5.0 μg/ml of penicillin or streptomycin significantly reduced the number of positive L-form cultures.
