  • Title: [Cross resistance in tumor cells and staphylococci with respect to anthracycline-group antineoplastic antibiotics].
    Author: Shorin VA, Averbukh LA.
    Journal: Antibiotiki; 1976 Oct; 21(10):914-9. PubMed ID: 999240.
    Abstract:
    The variants of the tumor cells of Fisher lymphadenosis, strain L-5178 and Staph. aureus resistant to rubomycin simultaneously became partially less sensitive to adriamycin. Sensitivity to karminomycin in the rubomycin resistant strains did not practically change as compared to the sensitivity of the initial strains. Sensitivity to adriamycin and rubomycin in Staph. aureus decreased 67 and 4 times respectively after 7 passages on media with increasing concentrations of adriamycin, while sensitivity to karminomycin decreased only 1.5 times, i.e. remained practically unchanged. After 22 passages of Staph. aureus to karminomycinrubomycin and adriamycin decreased 16, 67 and 33 times respectively. The results of the study may be explained by differences in the changes of the cell membrane permeability due to the drug effect.
