“…The genus Epidinium Crawley (1923) (family Ophryoscolecidae, order Entodiniomorphida) consists of spineless and spinated morphotypes. E. capricornisi [23], E. cattanei (syn. E. ecaudatum f. fasciculus) [24,25], E. parvicaudatum [12,25,26], and E. rusa [27] represent five-spine morphospecies between which confusion may occur in ecological studies [11,28].…”

An important feature of ruminal ciliates is their phenotypic plasticity, which makes their identification difficult. The common manifestation of the phenotypic plasticity in rumen ciliates is a change in their cell size and caudal spination. We analyzed various morphotypes of Epidinium with five caudal processes (spines) taken from the rumen of European bison (Bison bonasus). In the study, the cluster analysis and K-means analysis of morphometric data could not distinguish very similar morphotypes of Epidinium with five caudal processes. However, the morphotype of E. parvicaudatum prevailed (70%). The DNA of four individual E. parvicaudatum was isolated successfully from formaldehyde-preserved samples. The partial 18S rDNA gene sequences (about 350–400 bp) were identical to Epidinium sequences in GenBank (E. caudatum, a one-spine morphotype, and E. cattanei, a five-spine morphotype). It can be assumed that these short sequences cannot distinguish the differences between the Epidinium morphospecies. Complete gene sequences from various hosts and various molecular markers are necessary to reveal the validity of the Epidinium five-spine species. In conclusion, classical morphology should be supplemented with molecular data when more morphotypes of the rumen ciliate species are present in samples.

“…In Japanese seraw (Capricornis crispus TEMMINCK, 1854) from subfamily Rupicaprinae, the rumen microfauna contained 11 ciliate species (Imai et al 1981) among which 5 species were also found in our group of chamois, and in experimental material of other European writers. Neither the species Dasytricha ruminantium found in Japanese seraw nor other holotrichs were detected in the European chamois, and it was not found in our specimens.…”

Crha J., V. Hrabe,P. Koubek: Rumen Ciliate Fauna in the Chamois (Rupicapra rupicapra L.J. Acta vet. Brno, 54, 1985: 141-147. Total numbers, generic distribution and percentage species distribution were determined for the ciliate protozoa in rumen fluid obtained frem the chamois (Rupicapra rupicapra L.J. Ten individuals shot in the Jeseniky Mountains in November and December were used in the study. A total of 792000 ± 115 03~ ciliates were found per 1,0 ml of rumen fluid. Thirteen ciliate species were identified as follows: Entodinium cervi, Ent. dubardi, Ent. exiguum, Ent. laeve, Ent. loboso-spinosum, Ent. nanellum, Ent. parvum, Ent. rupicaprae, Ent. simplex , Diplodinium costa tum, Eremoplastron impalae, Eudiplodinium maggii and Epidinium ecaudatum. Ciliata, Entodiniomorphida, rumen, wild ruminants.Rumen ciliates of chamois were first studied by Wertheim (1934) The aim of the present study was to compare the ciliate fauna of the rumen of alpine chamois with that of the individuals of the introduced chamois popUlation residing in the Jeseniky mountains. Materials and MethodsCiliate fauna of the rumen of 10 chamois was examined. The animals were shot in the Jeseniky mountains in November and December 1982 (8 individuals -6 males, among them one kid and 2 females), and in the same months of 1983 (2 individuals -1 male and 1 female).After sampling, the rumen fluid was mixed with equal amount of 10 % formalin. Total numbers of ciliates and their generic distribution were determined in 1,0 ml rumen fluid using the Fuchs Rosenthal chamber. The individual ciliate species were determined both directly in a 5 % preservative formalin solution and after staining the nucleus (with acid carmine, Garazzi's glycerin hematoxylin, Heidenheim ferrous hematoxylin, methyl green)_ The skeletal plates were stained with chlorzincjodide and differentiated with concentrated sulphuric acid_ Specimens of the individual ciliate species were measured. Their identification was based on the descriptions of Dog i e I
