To date the genus Diploplastron comprised only one species of ophryoscolecid ciliate, affine, which is characterized by having two retractable ciliary zones in anterior end body, slender and juxtaposed skeletal plates on right side, a rod shape macronucleus, contractile vacuoles. During study characterization rumen ciliate community composition Brazilian domestic sheep, we observed ciliates with atypical morphology but diagnostic features Diploplastron. This describes dehorityi, new that...
The gastrointestinal tracts of most herbivorous mammals are colonized by symbiotic ciliates the subclass Trichostomatia, which form a well-supported monophyletic group, currently composed ∼1,000 species, 129 genera, and 21 families, distributed into three orders, Entodiniomorphida, Macropodiniida, Vestibuliferida. In recent years, trichostomatid have been playing part in many relevant functional studies, such as those focusing host feeding efficiency optimization investigating their role...
The validity of genus Eodinium has been historically disputed due to morphological similarities with Diplodinium (absence skeletal plates as well adoral and dorsal ciliary zones at the same body level). To address this issue, 18S rDNA four posterovesiculatum morphotypes anisacanthum were sequenced phylogenetically analyzed. different inference methods suggest existence a last common ancestor Ostracodinium that is not shared Diplodinium, strongly supporting Eodinium. Since are present in all...
The species composition, prevalence, and average relative abundance of rumen ciliates were analyzed in 16 Brazilian sheep. 28 identified belonging to 3 families: Isotrichidae, Ophryoscolecidae, Parentodiniidae. Among these ciliates, Entodinium alces, Metadinium esalqum, M. rotundatum found for the first time sheep, other 12 Different morphotypes parentodiniid 7 sheep this is second report family ruminants. contractum was redescribed based on new data general morphological features; time, we...
The family Ophryoscolecidae currently comprises 225 species of trichostomatid ciliates, subdivided into three subfamilies (Entodiniinae, Diplodiniinae, and Ophryoscolecinae). last taxonomic review the was performed 55 years ago, but recent morphological molecular studies indicate need for a profound systematics this taxon, since its current taxonomy is insufficient to organize diversity group. Here, we briefly based on information recovered from literature new data. We add four 18S rDNA...
The genus Diplodinium includes 31 species of ophryoscolecid ciliates with two retractable ciliary zones in the anterior end body, no skeletal plates, inclined macronucleus and contractile vacuoles. They have a broad geographical distribution low host specificity. has several taxonomic inconsistencies, mainly due to polymorphism most species. anisacanthum is case inconsistency genus. It presents posterior so it considered polymorphic or seven distinct This study morphological characterization...
The genus Metadinium includes ophryoscolecid ciliates, with two retractile ciliary zones in the anterior body portion, broad skeletal plates, a lobed macronucleus and contractile vacuoles. Species belonging to this were recorded several geographical locations different host species. However, they mostly described based on single ciliatological technique, until now, there is only one description of infraciliary pattern ciliates (Metadinium medium). present study performs morphological...
The objective were to identify and quantify the rumen protozoa from two genetic groups of beef cattle (Nellore crossbred European cattle) subjected three feeding systems (pasture, pasture supplement, confined). Samples contents obtained center ruminal mass after slaughter. Quantification identification performed with a Sedgewick-Rafter counting chamber by optic microscopy. Data analyzed using general linear analysis methodology Poisson distribution (1 %). In addition, data underwent Analisys...
SUMMARY The effects of cassava wastewater on nutrient digestibility and rumen protozoa were evaluated in 32 Santa Inês sheep fed a diet with Tifton hay, ground corn cob, concentrate, containing 0, 500, 1000, or 1500 mL wastewater. Uncastrated at an average age 167 days weight 25.3 kg housed individual stalls distributed randomized complete design four treatments eight replicates. experimental period was 70 days: 15 for adaptation to the diets 60 collect ingredients supplied. Prior this...
Several hundred ciliate species live in animals' guts as a part of their microbiome. Among them,
