Abstract: At Donghai Island,Zhanjiang,Guangdong,China were isolated 217 strains of bacteria from the water in 6 shrimp hatcheries,and their antibiotic resistance and susceptibility to 12 antibiotic agents was determined by using the Kirby-Bauer disc diffusion method for susceptibility testing. The results showed significant differences in bacterial resistance of the water to the 12 antibiotics( ANOVA,P < 0. 05). Bacteria of the water in the 6 hatcheries showed high susceptibility to polymyxin-B,levofloxacin,and ciprofloxacin and gave high resistance to ampicillin,trimethoprim,compound sinomi and tetracycline. Bacterial strains with multiple antibiotic resistances( MAR) were found in the water from each hatchery,and about 52. 07% of strains exhibited MAR,but none of the strains showed resistance to all 12 antibiotics. Statistical analysis indicated that no significant difference in antibiotic resistance of bacteria was observed in the water among the 6 hatcheries( ANOVA,P = 0. 273 > 0. 05) although antibiotic resistance of bacteria isolated from the water were higher in the hatcheries HM and XR than in the other hatcheries.
