OBJECTIVE: To evaluate the antimicrobial resistance of @entity8966 isolated from shellfish and its habitat in Sichuan, Fujian and Guangxi. METHODS: The susceptibility of 186 isolates of @entity8966 to 8 antibiotics were determined by broth microdilution susceptibility test. The antibiotics of @entity869 , @entity3524 , @entity5505 , @entity801 , @entity803 , @entity2755 , @entity2177 and @entity206 / @entity207 were used. RESULTS: The antibiotic resistance rate were 69.35% in which @entity869 resistance was the most prevalent. The geometric mean of @entity869 MIC value of all isolates was greater than the interpretation value of resistance. Among the 186 tested isolates, the multiple antibiotic resistance and/or intermediate resistance was 4. All strains were 100% sensitive to @entity3524 , @entity5505 , @entity2755 and @entity2177 . The @entity869 susceptibility spectrum of aquaculture farm was the highest among the three sectors as 73.68% and Sichuan was the highest among the three provinces as 70.94% although there were no significant differences. There were 44 samples out of which 2 and above strains were isolated, and the susceptibility spectrum polymorphism rate of strains isolated from the same sample was 77.27% (34/44). CONCLUSION: The @entity869 resistance rate is relatively high, and shellfish habitat may be the main source of antimicrobial resistance of @entity8966 . There is an urgent need to strengthen the surveillance and management of @entity8966 in the shellfish breeding process.
