摘要: The Galapagos Islands offer a unique ecological landscape found nowhere else in the world. However, lack of water and sanitation infrastructure within populated areas has potential to affect many these ecosystem attributes. Specifically, rapidly growing population expanding impacts tourism are contaminating coastal environments Islands. Water quality monitoring is conducted globally provide important information on incidence dangerous microbial contamination. Fecal indicator bacteria (such as Enterococcus spp. Escherichia coli) quantified proxies for presence pathogens that can be contaminated with human animal feces. These fecal bacteria, however, cannot used indicate specific source Recently, advancements have been made quantification other alternative markers contamination, such members Bacteroidales group. or gene predominantly gastrointestinal tract and, such, more accurate indicators pollution. In this study, we molecular techniques measurement DNA quantify both Bacteroides contamination waters San Cristobal Santa Cruz islands. marker concentrations were high enough certain locations warrant concern. Human pollution was present marine beach brackish lagoon popular bathing recreation. Since our wastewater treatment plant upgraded, possibly resulting reduced results poor management could posing threat health residents tourists, Improvements critical protect inhabitants, fragile components ensure long-term viability sustainability place.
