Abstract:
Fecal pollution from nonpoint and point sources were evaluated in a constructed wetland in Tolleson, Arizona. Escherichia coli blooms in the wetland effluent were attributed to both human and animal sources. Antibiotic resistance profiling and biochemical fingerprinting was performed on 325 Escherichia coli isolates collected from key points in the wetlands and the avian population. Multivariate statistical analysis was used to interpret the data for samples collected on October 3, 2000, 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, 2000 and December 12, 2000, whereas the regrowth in the treated municipal wastewater was the main source in January 16, 2001. In addition, 77 percent of the isolates from the human population were multiple antibiotic resistant to two or more antibiotics, with the highest resistance to ampicillin (50.7%), carbenicillin (39.4%), cephalothin (81.7%), streptomycin (49.0%) and sulfisoxazole (32.4%).
