3.4. Drug sensitivity tests for the SZ01 strain
Next, the sensitivity of the SZ01 strain to 17 different antibiotics was investigated. Results showed that SZ01 was only sensitive to ciprofloxacin and sulfisoxazole and moderately sensitive or resistant to the other drugs. Among these drugs, sulfisoxazole, florfenicol and neomycin are allowed to be used in aquaculture (Table 2).
