Sensitivity Testing of Different Serotypes of Avian E. coli Bacteria for the Same Drug
Abstract: This paper studied the sensitivities of different serotypes of avian
E. coli for the same drug by the drug sensitivity tests, and provide theoretical basis for clinical treatment. In this experiment, 6 serotypes of the bacteria were gained from nine strains of 25 species, and the high-sensitivity drugs were screened from 26 antibiotics for the six E. coli bacteria. The results showed that 6 serotypes of the bacteria were high-sensitivity for 10 kinds of drugs such as pioneer V, chloramphenicol and junbizhi, showed resistance to 10 kinds of drugs, and were inconsistent sensitivity for the other 6 kinds of drugs. From those results, 10 high-sensitivity drugs, ofloxacin and kanamycin were recommended to use in treating the E. coli disease.
