Studied on sensitivities of C. ellipsoidea to kanamycin , Chloromycetin , Hygromycin , Streptomycin and Geneticin (G418), the results showed that C. ellipsoidea is not sensitive to Km, Str and Cm, 600μg/ml km, 600μg/ml Str and 200μg/ml Cm can not inhabited the growth of C. ellipsoidea. However, it is fairly sensitive to Hm, 100μg/ml can completely stop the growth of C. ellipsoidea on solid media. We also found that C. ellipsoidea was highly sensitive to G418, 30μg/ml and 15μg/ml can inhabit the growth of C.
