Abstract
Penicillin-resistant and lysozyme-resistant strains were induced by culturing Micrococcus lysodeikticus and other micrococci isolated from ea and air in penicillin- and lysozyme-containing media. These strains were subcultured repeatedly on nutrient agar, and the cross resistance of the resistant strains were observed to the other antibacterial agents with the following results.
1. The resistance of resistant strains was decreased bar the repeated subculture on nutrient agar.
2. Penicilain-resistant strains exhibited a marked cross resistance to streptomycin, erythromycin, aureemycin and trypaflavine. Howe~-er, lysozyme-resistant strains did not exhibit any significant cross resistance to these drugs.
