TLDR
The distribution of Cryptosporidium species, G. duodenalis genotypes and subtypes, and E. bieneusi genotypes in urban wastewater indicates that anthroponotic transmission appeared to be important in epidemiology of cryptosporidiosis, giardiasis, and microsporidia in the study areas.Abstract:
Background
Despite their wide occurrence, cryptosporidiosis and giardiasis are considered neglected diseases by the World Health Organization. The epidemiology of these diseases and microsporidiosis in humans in developing countries is poorly understood. The high concentration of pathogens in raw sewage makes the characterization of the transmission of these pathogens simple through the genotype and subtype analysis of a small number of samples.read more

Diverse Applications of Environmental DNA Methods in Parasitology.
TL;DR: Focusing on eukaryote parasites, the increasing diversity of the 'eDNA toolbox' is reviewed and combining eDNA methods with complementary tools offers much potential to understand parasite communities, disease risk, and parasite roles in broader ecosystem processes such as food web structuring and community assembly.

Molecular epidemiologic tools for waterborne pathogens Cryptosporidium spp. and Giardia duodenalis.
Lihua Xiao,Yaoyu Feng +1 more
TL;DR: Differences in virulence have been identified among Cryptosporidium species and subtypes, and possibly between G. duodenalis assemblages A and B, and genetic recombination has been identified as one mechanism for the emergence of virulent C. hominis subtypes.

TL;DR: It was concluded that humans and NHPs residing in the same geographical location shared the same E. bieneusi genotypes, indicating a potential role of these animals in the zoonotic transmission of E.Bieneus i in nonhuman primates.

Zoonotic Potential and Molecular Epidemiology of Giardia Species and Giardiasis
Yaoyu Feng,Lihua Xiao +1 more
TL;DR: The authors' efforts in characterizing the molecular epidemiology of giardiasis are compromised by the lack of case-control and longitudinal cohort studies and the sampling and testing of humans and animals living in the same community, the frequent occurrence of infections with mixed genotypes and subtypes.

TL;DR: The wide use of a new generation of genotyping and subtyping tools in well designed epidemiologic studies should lead to a more in-depth understanding of the epidemiology of cryptosporidiosis in humans and animals.

TL;DR: The current state of knowledge of Giardia and Cryptosporidium is summarized here, and some important questions are raised that need to be addressed if control strategies are to be effective.

TL;DR: Genotyping and subtyping data suggest that zoonotic transmission is not as prevalent in the epidemiology of giardiasis, and the most prevalentZoonotic species is Cryptosporidium parvum.
