Interpretive Summary: Theileria parva, an intracellular protozoan parasite, is the leading infectious cause of death of cattle in sub-Saharan Africa. Current preventive strategies are incredibly limited, and improved vaccination and treatment strategies are urgently needed to decrease the socioeconomic impact of this parasite. One significant hindrance to the development of a new vaccine or new treatment modalities is the lack of specific antigenic targets within the parasite. This work re-annotated the T. parva genome to allow for more accurate characterization of parasite genes so that new vaccine and therapeutic targets can be selected and tested. This re-annotation will enable future work in vaccine and treatment development in this disease.
Technical Abstract: Genome annotation remains a significant challenge because of limitations in the quality and quantity of the data being used, as well as the underlying biological complexity of the processes involved in gene expression. However, comprehensive and descriptive genome annotations are valuable resources for answering biological research questions and discovering novel chemotherapeutic targets for disease treatment. Here, we use our recently published RNAseq dataset derived from the schizont life-cycle stage of the apicomplexan parasite Theileria parva, which causes a devastating livestock disease in sub-Saharan Africa, to update structural and functional annotations across the entire genome. The process of re-annotation led to novel insights into gene expression in this parasite, as well as uncovers potential chemotherapeutic targets to treat infection.
