Determination of phylogenetic relationships among Eimeria species, which parasitize cattle, on the basis of nuclear 18S rDNA sequence.

ABSTRACT: We analyzed almost complete 18S rDNA sequences of 10 bovine Eimeria species, namely Eimeria alabamensis, E. auburnensis, E. bovis, E. bukidnonensis, E. canadensis, E. cylindrica, E. ellipsoidalis, E. subspherica, E. wyomingensis and E. zuernii. Although these sequences showed intraspecific variation in 8 species, the sequences of each species were clustered in monophyletic groups in all species, except E. auburnensis. The sequences constituted 3 distinct clusters in a phylogenetic tree with relatively high bootstrap values; however, the members including each cluster shared no similarities in oocyst morphology.
