Aerobic plate counts of fresh pond-reared shrimp ( Penaeus stylirostris , Penaeus vannamei , and Penaeus setiferus ) ranged from 1.5 × 10 to 1.3 × 10 per gram. Coryneform bacteria and Vibrio spp. dominated the microbial flora of shrimp. Aerobic plate counts of pond waters ranged from 6.1 × 10 to 2.2 × 10 per milliliter. Vibrio spp. usually were dominant in pond waters. Enterococci and coliform levels in shrimp were low. Fecal coliforms were present in only one of 11 shrimp samples. No Escherichia coli was recovered from pond-reared shrimp. Salmonella , Vibrio parahaemolyticus , Bacillus cereus , and Clostridium perfringens were not recovered from either shrimp or pond waters. No relationship could be established between changes in numbers and types of microorganisms in pond-reared shrimp or pond waters and changes in characteristics of the pond waters such as temperature, salinity, dissolved oxygen, and pH.
新鲜池塘养殖虾（斯氏对虾、凡纳滨对虾和长缝对虾）的需氧平板计数范围为每克1.5×10至1.3×10。棒状杆菌属细菌和弧菌属细菌在虾的微生物菌群中占主导地位。池塘水的需氧平板计数范围为每毫升6.1×10至2.2×10。弧菌属细菌通常在池塘水中占主导地位。虾中的肠球菌和大肠菌群水平较低。11份虾样本中只有1份存在粪大肠菌群。未从池塘养殖虾中分离出大肠杆菌。未从虾或池塘水中分离出沙门氏菌、副溶血性弧菌、蜡样芽孢杆菌和产气荚膜梭菌。在池塘养殖虾或池塘水中微生物数量和种类的变化与池塘水的温度、盐度、溶解氧和pH值等特性变化之间无法建立联系。
