| environmental transport of emerging human-pathogenic cryptosporidium species and subtypes through combined sewer overflow and wastewater. | the environmental transport of cryptosporidium spp. through combined sewer overflow (cso) and the occurrence of several emerging human-pathogenic cryptosporidium species in developing countries remain unclear. in this study, we collected 40 cso samples and 40 raw wastewater samples from shanghai, china, and examined them by pcr and dna sequencing for cryptosporidium species (targeting the small subunit rrna gene) and giardia duodenalis (targeting the triosephosphate isomerase, β-giardin, and glu ... | 2017 | 28600310 |
