hydrogenosomes in a mixed isolate of isotricha prostoma and isotricha intestinalis from ovine rumen contents.1. both isotricha intestinalis and i. prostoma possess microbody-like organelles, with a highly granular appearance. 2. these organelles, which are sedimentable at 10(5) g-min, bear no morphological similarity to mitochondria, but are enzymatically similar to organelles possessed by certain other anaerobic protozoa and termed hydrogenosomes. 3. the hydrogenosomes isolated from a preparation of mixed isotrichs bear a closer similarity to those isolated from the other rumen holotrich. dasytricha r ...19836403285
ruminal fermentation and duodenal flow following progressive inoculations of fauna-free wethers with major individual species of ciliate protozoa or total fauna.naturally fauna-free (ff) wethers, equipped with ruminal and duodenal cannulas, were used in two groups of eight (group a) and seven (group b) animals in six consecutive experimental periods, each lasting for 28 d. the objective was to measure ruminal fermentation traits, and flows of nonammonia nitrogen (nan), total amino acid (taa), and bacterial nitrogen (bn) from the stomach after inoculation with individual ciliate protozoa species in each period. the wethers in both groups were fed a diet ...200010764084
the rumen ciliate fauna of domestic sheep (ovis ammon aires) from the turkish republic of northern cyprus.concentration and composition of ciliate protozoa in the families ophryoscolecidae and isotrichidae were determined in rumen contents of domestic sheep (ovis ammon aries) from cyprus. a total of five genera of ophryoscolecidae were identified, metadinium, enoploplastron, polyplastron, epidinium, and ophrvoscolex, which included six species: metadinium affine, enoploplastron triloricatum, polyplastron multivesiculatum, epidinium ecaudatum, epidinium graini, and ophryoscolex purkynjei. eight separ ...200111456322
potential of galvanotaxis to separation and cleaning of rumen ciliates.the ability of rumen ciliate protozoa to move in a unidirectional electrical field from the anode to the cathode was tested in large-volume electromigration equipment; the aim was to concentrate the microorganisms and clean them of impurities. during galvanotaxis in the freshly harvested rumen fluid and at a voltage of 10 v (i=0.8 ma), cells of isotricha (isotricha prostoma, isotricha intestinalis) were the first to swim towards the cathode; 1 min later, they were followed by dasytricha ruminant ...200415003689
