Fig. 1From: Molecular characterization of the waterborne pathogens Cryptosporidium spp., Giardia duodenalis, Enterocytozoon bieneusi, Cyclospora cayetanensis and Eimeria spp. in wastewater and sewage in Guangzhou, ChinaPhylogenetic relationship of Enterocytozoon bieneusi genotypes detected in samples collected from wasterwater treatment plants and sewer samples as determined by a maximum-likelihood analysis of the ribosomal internal transcribed spacer based on substitution rates calculated using the general time-reversible model and gamma distribution. Known and novel genotypes identified in this study are indicated by blue and red triangles, respectively. Bootstrap values of < 50% from 1000 replicate analysis are not shownBack to article page
