[A revision of the taxonomy of Cryptosporidium and provided guidelines for all future naming of species. Impact factor 13.194, 203 citations. Ranked 4th out of all Microbiology Journals.]

2. Xiao, L and Ryan, U. 2004. Cryptosporidiosis: an update in molecular epidemiology. Current Opinion in Infectious Diseases. 17:483-490.
[Impact factor: 4.79. 72 citations. Ranked 13th out of all Infectious Disease Journals.]

3. Hijjawi, N.S. Meloni, B.P. Ng'anzo, M. Ryan, U.M. Olson, M. E., Cox, P. T. Monis, P.T. and Thompson, R.C.A. 2004. Complete development of Cryptosporidium parvum in host cell free culture. International Journal for Parasitology. 34:769-77.
[This is the first publication showing that Cryptosporidium can be cultured in the absence of host cells. This was a significant advance in the understanding of the biology of Cryptosporidium, with important practical implications for detection and viability assays in the water industry and for the development of a Cryptosporidium vaccine. Impact factor: 3.34. 25 citations. Ranked 4th out of all Parasitology Journals.]
