Antibiotic resistance genes (ARGs) greatly limit the aquaculture development in China. In this study
194 strains of bacteria were identified with an improved boiling method for DNA extraction. Polymerase chain reaction (PCR) assay was applied to detect the antibiotic resistance genes of florfenicol (floR)
two sulfonamide (sul1 and sul2)
streptomycin (str)
trimethoprim (dfrA20) in 139 bacterial strains. It showed that 194 strains were identified as 62 different species
mainly Lysine Bacillus
Vibrio parahaemolyticus
Aeromonas media
Aeromonas hydrophila
Aeromonas sobria
Bacillus cereus
Citrobacter freundii
Chryseobacterium ureilyticum
Pseudoalteromonas whanghaensis
Vibrio cholerae and so on. ARGs of floR
sul1
sul2
str and dfrA20 in 139 strains were detected with positive rate of 11.51%
20.86%
12.23%
10.07% and 2.88%
respectively. The results showed that antibiotic resistance genes could be the potential emerging pollutants in aquaculture organisms and aquatic environment.
