Geometric morphometric on a new species of Trichodinidae. A tool to discriminate trichodinid species combined with traditional morphology and molecular analysis

International Journal for Parasitology: Parasites and Wildlife, 2018
This study reports a new Trichodinidae, Trichodina bellottii n. sp., parasitizing the pearly fish Austrolebias bellottii from Buenos Aires, Argentina. Its small subunit ribosomal ribonucleic acid (SSU rDNA) was sequenced for the first time.

RT-PCR specific for Cryspovirus is a highly sensitive method for detecting Cryptosporidium parvum oocysts

Food and Waterborne Parasitology, 2016
Cryptosporidium parvum represents a considerable health risk to humans and animals because the parasite has a low infectious dose and is usually present at low numbers in environmental samples, which makes detection problematic. The purpose of this study

rDNA Variability Assessed in PCR Reactions of Selected Accessions of Acer

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2011
The region of rDNA (SSU, 5.8S, LSU and ITS1, ITS2 spacer sequences) of fourteen Acer accessions was tested in order to determine the possibility to identify genotypic variability within a rDNA sequence.

Morphological plasticity in Myxobolus Bütschli, 1882: a taxonomic dilemma case and renaming of a parasite species of the common carp

Parasites & Vectors, 2018
Background Myxozoans are a group of cnidarian parasites, the present taxonomy of which favors a more comprehensive characterization strategy combining spore morphology, biological traits (host/organ specificity, tissue tropism), and DNA data over the ...

Acaulospora jejuensis, a New Species in Glomeromycota from Korea

한국균학회지, 2021
New species of arbuscular mycorrhizal fungi (Glomeromycota), Acaulospora jejuensis, was isolated from rhizosphere soils of Miscanthus sinensis in the grassland in Jeju Island of Korea. The species was identified using the morphological characteristics of
