Monitoring drinking water quality is an important public health issue and pathogenic organisms present a particularly serious health hazard in freshwater bodies. However, many pathogenic bacteria, including cyanobacteria, and pathogenic protozoa can be swept into coastal lagoons and into near-shore marine environments where they continue to grow and pose a health threat to marine mammals and invertebrates. In this study, we tested the suitability of a phylochip (microarray for species detection) developed for freshwater pathogenic organisms to be applied to samples taken across a marine/freshwater interface at monthly intervals for two years. Toxic cyanobacteria and pathogenic protozoa were more numerous in a coastal lagoon than at the freshwater or marine site, indicating that this microarray can be used to detect the presence of these pathogens across a marine/freshwater interface and thus the potential for toxicity to occur within the entire watershed.

监测饮用水质量是一个重要的公共卫生问题，病原生物在淡水体中尤其构成严重的健康危害。但是，许多致病细菌，包括蓝细菌和致病原生动物，都可以被卷入沿海泻湖和近岸海洋环境，在那里它们继续生长并对海洋哺乳动物和无脊椎动物构成健康威胁。在这项研究中，我们测试了为淡水病原生物开发的系统芯片（用于物种检测的微阵列）的适用性，该系统每月两次应用于海洋/淡水界面上采集的样品。沿海泻湖中的有毒蓝细菌和致病性原生动物比淡水或海洋场所多，
