Theileria terrestris nov. sp.: A Novel Theileria in Lowland Tapirs (Tapirus terrestris) from Two Different Biomes in Brazil

open access: yesMicroorganisms, 2022
The low-land tapir (Tapirus terrestris) is the largest wild terrestrial mammal found in Brazil. Although T. terrestris has been already reported as a host of hemoparasites, the occurrence and genetic identity of Piroplasmida agents in this species is ...

Origin of the Mesozoa inferred from 18S rRNA gene sequences [PDF]

open access: yesMolecular Biology and Evolution, 1996
The phylum Mesozoa comprises small, simply organized wormlike parasites of marine invertebrates and is composed of two classes, the Rhombozoa and the Orthonectida. The origin of Mesozoa is uncertain; they are classically considered either as degenerate turbellarians or as primitive multicellular animals related to ciliated protists.

Characterization of the two intra-individual sequence variants in the 18S rRNA gene in the plant parasitic nematode, Rotylenchulus reniformis. [PDF]

open access: yesPLoS ONE, 2013
The 18S rRNA gene is fundamental to cellular and organismal protein synthesis and because of its stable persistence through generations it is also used in phylogenetic analysis among taxa.

Molecular differentiation of Thysaniezia (Helictometra) giardi and Moniezia species based on 18s rRNA gene in small ruminants [PDF]

open access: yesIraqi Journal of Veterinary Sciences, 2021
This study was conducted to investigate Anoplocephalidia Cestoda in sheep and goat and evaluate the 18s rRNA to genetically differentiate the genera of this family. Sixty sample tapeworms were collected from small intestines of 30 sheep and 30 goats from

Validation of a PNA Clamping Method for Reducing Host DNA Amplification and Increasing Eukaryotic Diversity in Rhizosphere Microbiome Studies

open access: yesPhytobiomes Journal, 2020
Protists and microscopic animals are important but poorly understood determinants of plant health. Plant-associated eukaryotes could be surveyed by high-throughput sequencing of 18S ribosomal RNA (rRNA) genes but the abundance of plant DNA in rhizosphere

Parasites and blood-meal hosts of the tsetse fly in Tanzania: a metagenomics study

open access: yesParasites & Vectors, 2022
Background Tsetse flies can transmit various Trypanosoma spp. that cause trypanosomiasis in humans, wild animals, and domestic animals. Amplicon deep sequencing of the 12S ribosomal RNA (rRNA) gene can be used to detect mammalian tsetse hosts, and the ...

Phylogenetic heterogeneity of the genus Williopsis as revealed by 18S rRNA gene sequences [PDF]

open access: yesInternational Journal of Systematic Bacteriology, 1998
A phylogenetic investigation of the ascomycetous yeast genus Williopsis was performed by using 18S rRNA gene sequence analysis. Comparative sequence analysis revealed the genus to be phylogenetically heterogeneous. The five varieties of Williopsis saturnus [var. mrakii, var. sargentensis, var. saturnus (type), var. suaveolens and var.

Reference genes for quantitative real-time PCR analysis and quantitative expression of P5CS in Agropyron mongolicum under drought stress

open access: yesJournal of Integrative Agriculture, 2016
Reference genes, stably expressing in different tissues and cells, are commonly used as the references in expression analysis. Selecting the optimum reference gene is crucial to the success of experiments.

Molecular Survey of Piroplasmids and Hemosporidians in Vampire Bats, with Evidence of Distinct Piroplasmida Lineages Parasitizing Desmodus rotundus from the Brazilian Amazon

open access: yesParasitologia, 2023
Although bats can serve as reservoirs for several viruses and bacteria, there is limited knowledge regarding the diversity of apicomplexan protozoan belonging to the Piroplasmida and Haemosporida orders within this group of mammals.

Ecological assessment of phytoplankton community via microscopic method and 18S rRNA gene sequencing in Pearl River Estuary [PDF]

open access: yesE3S Web of Conferences, 2019
Monitoring phytoplankton community underpins our understanding of water quality and ecological functions. In this study, we approached phytoplankton abundance, community composition, and diversity by both microscopy and 18S rRNA gene sequencing ...
