Methods The Salmonella, Staphylococcus aureus, Listeria monocytogenes, Escherichia coli O157 and Vibrio parahaemolyticus in 70 samples of Procambarus clarkii and 40 samples of external environmental water were tested according to the national standards of food microbiological examination. Then the serotype distribution of Salmonella were identified, and the drug resistances of Salmonella and Staphylococcus aureus were determined by Kindy-Bauer (KB) method. Results The total detection rate of pathogenic bacteria in Procambarus clarkii was 41.43%. The pathogenic bacteria included Salmonella, Staphylococcus aureus, Vibrio parahaemolyticus and Listeria monocytogenes. The total detection rate of pathogenic bacteria in external environmental water was 基金项目 : Fund: Supported by the Soft Subject of Natural Science in Huai an City. * 通讯作者 :,, E-mail: 546650546@qq.com *Corresponding author: LIU Liang, Supervising Technician, Huai an Center for Disease Control and Prevention, Huai an 223001, China.

9, : 3531 22.50%, and the pathogenic bacteria included Staphylococcus aureus, Salmonella and Vibrio parahaemolyticus. Salmonella isolates showed high resistance to nalidixic acid and ampicillin, and Staphylococcus aureus isolates showed high resistance to erythromycin, trimethoprim/sulfamethoxazole and clindamycin. Conclusion There is pollution of pathogenic bacteria in Procambarus clarkii and its external environment water in Huai an, and the drug resistance of Salmonella and Staphylococcus aureus was serious.
