NATURALLY OCCURING ANTIBIOTIC RESISTANCE IN BACILLUS SPHAERICUS / 微生物学通报

The naturally occuring antibiotic resistance in twentyseven strains from 7 different serotypes of Bacillus sphaericus was investigated. The antibiotics used in this experiment are Streptomycin, Ampicilline, Tetracycline, Chloramphenicol, Kanamycin, Erythromycin, Qingdamycin, Midecamycin, Ribostamycin, Acriflavin, Rifampicin, Sulphanilamide and Azide. All strains are resist to streptomycin and azide at higher concentration and chloramphenicol at lower concentration. Most of strains are resist to tetracycline at lower concentration.
