Molecular characterization of Cryptosporidium parvum anthroponosum – a new threat to world health. (TylerKU19SF)


Project Description

Human cryptosporidiosis is the leading protozoan cause of diarrhoeal mortality worldwide, and most infection is caused by either person to person transmitted Cryptosporidium hominis or the presumptively zoonotic C. parvum. However, C. parvum actually splits into two subclades. One, which we have newly identified as C. parvum anthroponosum is also predominantly spread person to person and shares a subset of loci with C. hominis that are undergoing rapid convergent evolution driven by positive selection. This subspecies predominates in lower-income countries with poor sanitation and in HIV positive individuals, in contrast to higher-income countries where it is rarely evident.

In the course of their studies the student will characterize this new subspecies of parasite providing an annotated reference genome, will evaluate whether its virulence is greater than the zoonotic form, propagating the parasite and genetically transforming it to evaluate the role of the shared loci in adaptation to the human digestive tract.

The student will further develop diagnostic tools to discriminate this group of parasites. The student will be supported by Earlham institute for the genomic aspects of the project and will be affiliated with the EU interreg program H4DC on cryptosporidium which is concerned with production of new drugs and diagnostics for cryptosporidium.
