Chemical parameters and occurrence of Cryptosporidium spp., in raw and treated water from Nariño, Colombia

Water-borne transmission of Cryptosporidium has been highly reported around the world. Cryptosporidium infective oocysts have demonstrated remarkable resistance. Oocyst can interact with suspended and dissolved particles from water contamination, decreasing disinfection process efficacy. Detection from water and genotyping methods of Cryptosporidium are not enough, suggesting a research challenge in detection of potential human circulating pathogens strains. To analyse the influence of chemical parameters and presence of Cryptosporidium in raw and drinking waters collected from three sampling sites in Narino province, Colombia.
