ABSTRACT
The parasite Cryptosporidium is a leading cause of diarrhea and death in malnourished children and immunocompromised individuals and an important enteric pathogen of livestock. A mucosal vaccine to mitigate clinical disease and decrease transmission would address the public health impact of this organism, but current options are limited. The development of a rational strategy for vaccination requires an appreciation of the parasite lifecycle, how Cryptosporidium interacts with its host cell (the enterocyte), and the immune mechanisms that act locally to control this organism. Here we review current knowledge of the adaptive immune mechanisms that mediate resistance to Cryptosporidium, their relevance to vaccine design, and how recent advances in parasite genetics inform vaccine development.
