这项研究的目的是量化经常出现在海滩的不同动物所产生的微生物负荷（肠球菌）。狗粪便中肠球菌浓度最高，平均为3.9×107CFU/g；第二高的肠球菌水平在鸟类中观察到，平均为 3.3×105CFU/g。在从虾粪堆收集的材料中观察到肠球菌的最低测量水平（2.0CFU/g）。微生物负荷的比较表明，1个狗粪便事件相当于6940个鸟粪便事件或3.2×108个虾粪便堆。将动物的贡献与之前公布的人类游泳者排泄物的数据进行比较表明，一名成年人类游泳者贡献的微生物量与一名鸟类粪便事件的微生物量大致相同。鉴于海滩上观察到的动物数量众多，这项研究表明狗是海滩上肠球菌的最大动物来源。
The goal of this study was to quantify the microbial load (enterococci) contributed by the different animals that frequent a beach site. The highest enterococci concentrations were observed in dog feces with average levels of 3.9×107CFU/g; the next highest enterococci levels were observed in birds averaging 3.3×105CFU/g. The lowest measured levels of enterococci were observed in material collected from shrimp fecal mounds (2.0CFU/g). A comparison of the microbial loads showed that 1 dog fecal event was equivalent to 6940 bird fecal events or 3.2×108shrimp fecal mounds. Comparing animal contributions to previously published numbers for human bather shedding indicates that one adult human swimmer contributes approximately the same microbial load as one bird fecal event. Given the abundance of animals observed on the beach, this study suggests that dogs are the largest contributing animal source of enterococci to the beach site.
