Abstract

Determination of antimicrobial wild-type minimum inhibitory concentration (MIC) distributions is a prerequisite before differentiating susceptible bacteria from bacteria with acquired resistance. The antimicrobial susceptibility was determined for 190 strains of eight species of the Lactobacillus delbrueckii group. These were L. acidophilus, L. amylovorus, L. crispatus, L. delbrueckii, L. helveticus, L. gallinarum, L. gasseri and L. johnsonii. For most antimicrobial agents a clear distinction between susceptible and resistant bacteria was observed. Tetracycline resistance was abundant among L. johnsonii and L. amylovorus strains isolated from animals, while the L. delbrueckii and L. helveticus strains isolated from dairy products, and L. gasseri isolated from humans, rarely contained acquired resistance.
