Abstract

Cryptosporidium parvum can be reliably genetically manipulated using CRISPR/Cas9 driven homologous repair coupled to in vivo propagation in immunodeficient mice. This chapter will guide through foundational procedures for excystation, transfection, infection, collection, and purification of transgenic Cryptosporidium parvum. The genetic tools for Cryptosporidium research were expanded significantly over the last 5 years. While we cannot cover all advances in detail, we will highlight novel selection markers, conditional mutagenesis strategies, and genetic crosses.
