Little information has been gathered on the effect of avian species on the microbial water quality in constructed wetlands. To address this concern, fecal pollution from nonpoint and point sources was evaluated in a constructed wetland in Tolleson, Arizona. Antibiotic resistance profiling and biochemical fingerprinting were performed on 325 Escherichia coli isolates, collected from key points in the wetlands. Multivariate statistical analysis was used to interpret the data for samples collected on October 3 and December 12, 2000, and January 16, 2001. It was found that the passerine population was the major source of the Escherichia coli in the water samples collected in the wetlands on October 3 and December 12, 2000, whereas the regrowth in the treated municipal wastewater was the main source on January 16, 2001. This information is useful in providing data for operators in the monitoring of wetlands created for wastewater treatment and wildlife habitat.
关于鸟类物种对人工湿地微生物水质的影响，目前收集到的信息很少。为了解决这一问题，在亚利桑那州托利森的一个人工湿地中，对非点源和点源粪便污染进行了评估。对从湿地关键点采集的325株大肠杆菌分离株进行了抗生素抗性分析和生化指纹图谱分析。采用多变量统计分析对2000年10月3日、12月12日和2001年1月16日采集的样本数据进行了解释。结果发现，雀形目鸟类种群是2000年10月3日和12月12日在湿地采集的水样中大肠杆菌的主要来源，而2001年1月16日处理后的城市废水中的再生长是主要来源。这些信息有助于为操作人员提供数据，以便监测为废水处理和野生动物栖息地而建造的湿地。
