Cryptosporidium: host and parasite transcriptome in infection

Cryptosporidium is a waterborne gastrointestinal parasite that causes outbreaks of diarrheal disease worldwide. Despite the impact of this parasite on human health there are no effective drugs or vaccines. Transcriptomic data can provide insights into host-parasite interactions that lead to identification of targets for therapeutic interventions. However, for Cryptosporidium, interpreting transcriptomes has been challenging, in part due to the presence of multiple life cycle stages, the lack of appropriate host cells and the inability to culture the parasite through its complete life cycle. The recent improvements in cell culture and the ability to tag and isolate specific life cycle stages will radically improve transcriptomic data and advance our understanding of Cryptosporidium host-parasite interactions.
