title: In vitro susceptibility of Haemophilus somnus to 33 antimicrobial agents.
abstract: Minimal inhibitory concentrations of 33 antimicrobial agents for Haemophilus somnus were determined by the agar dilution method. The tested H. somnus strains were highly susceptible to penicillin G, ampicillin, colistin, and novobiocin. They were not susceptible to spiramicin and sulfadimethoxine, and streptomycin-resistant strains were found.
