Morphometric variations of the rumen ciliate, Ophryoscolex purkynjei Stein, 1858 (Ciliophora: Entodiniomorphida) from cypriot domestic goats

The species Ophryoscolex purkynjei and its four formae [O. p. f. purkynjei, O. p. f. bifidobicinctus, O. p. f. bicoronatus and O. p. f. tricoronatus] from the Cypriot domestic goats (Capra hircus) have been investigated from the viewpoint of the diagnostic morphometrical characteristics. Moreover, it was demonstrated that there was significant morphometrical variations among the same formae in different host animals. As the result of our investigation, it has been suggested that all of the morphometrical variations determined may originate from the individual physiological differences of the host animals (e.g. the other ciliate fauna, bacterial population, inter-specific antagonism etc.).
