Together with the Striepen laboratory at the University of Georgia and the Mead laboratory at Emory University, we are mining the genome of Cryptosporidium to identify new drug targets.  Surprisingly, Cryptosporidium has obtained several genes via lateral transfer from bacteria;  the proteins encoded by these genes are highly diverged from their host counterparts, which should facilitate the development of specific inhibitors.
