Trichosomoides nasalis (Trichinelloidea) is a parasite of Arvicanthis niloticus (Muridae) in Senegal. Female worms that harbour dwarf males in their uteri, occur in the epithelium of the nasal mucosa. Young laboratory-bred A. niloticus were either fed females containing larvated eggs or intraperitoneally injected with motile first-stage larvae recovered from female uteri. Both resulted in successful infection. Organs examined during rodent necropsy were blood and lymphatic circulatory systems (heart, large vessels, lymphnodes), lungs, liver, kidneys, thoracic and abdominal cavities, thoracic and abdominal muscular walls, diaphragm, tongue, and nasal mucosa. Development to adult nasal stages took three weeks. Recovery of newly hatched larvae from the peritoneal fluid at four-eight hours after oral infection suggests a direct passage from the stomach or intestinal wall to the musculature. However, dissemination through the blood, as observed with Trichinella spiralis, cannot be excluded even though newly hatched larvae of T. nasalis are twice as thick (15 mum). Developing larvae were found in histological sections of the striated muscle of the abdominal and thoracic walls, and larvae in fourth moult were dissected from these sites. Adult females were found in the deep nasal mucosa where mating occurred prior to worms settling in the nasal epithelium. The present study shows a remarkable similarity between T. nasalis and Trichinella species regarding muscle tropism, but the development of T. nasalis is not arrested at the late first-larval stage and does not induce transformation of infected fibres into nurse cells. T. nasalis seems a potential model to study molecular relations between trichinelloid larvae and infected muscle fibres.

(+info)Cell lineage in marine nematode Enoplus brevis. (6/6)
Early cleavages of the marine nematode Enoplus brevis are symmetrical and occur in synchrony. At the 2- to 16-cell stages, blastomeres are indistinguishable. The progeny of blastomeres was investigated by intracellular injections of fluorescent dyes and horse radish peroxidase. One blastomere of the 2-cell embryo gives rise to a compact group of cells occupying about half of an embryo. The border between labeled and unlabeled cells differs in each embryo dividing it to anterior-posterior, left-right or intermediate parts. At the 8-cell stage, one blastomere gives rise to only endoderm, whereas the other blastomeres produce progeny that form multiple cell types, including nerve, muscle and hypoderm cells, in various proportions. Thus the fates of the blastomeres of early E. brevis embryos, with the exception of the endoderm precursor, are not determined. The process of gastrulation in E. brevis is very similar to that in Caenorhabditis elegans and other nematodes. At the beginning of gastrulation, the 2-celled endoderm precursor lies on the surface of embryo and then sinks inwards. After labeling of cells on the ventral side (near endoderm precursor) at the beginning of gastrulation, their progeny differentiate predominantly into body muscles or pharyngeal cells of the first stage larva. Cells that are located more laterally give rise mainly to neurons. The dorsal blastomeres differentiated principally into hypoderm cells. Our study suggests that a precise cell lineage is not a necessary attribute of nematode development. (+info)Enoplida is a taxonomic class of marine worms belonging to the phylum Nematoda, also known as roundworms. This group includes several genera and families of free-living and parasitic species. Enoplida worms are characterized by their elongated, slender bodies and the presence of a retractable stylet or spear-like structure in their mouthparts, which they use for feeding on bacteria, algae, or other small organisms. Some species can be found in various aquatic environments, including marine and freshwater habitats, while others are associated with terrestrial ecosystems.
It is important to note that the classification of nematodes has undergone significant revisions in recent years due to advances in molecular phylogenetics. As a result, some traditional taxonomic groups, such as Enoplida, may no longer be recognized or have their composition altered. For up-to-date information on the classification and medical relevance of these organisms, it is recommended to consult specialized scientific literature or databases.
Enoplida is a group of nematodes (roundworms) that are not typically associated with human infections. There are very few reports of human infections caused by Enoplida, and these are usually the result of accidental ingestion or penetration of the skin by the worms.
There is no established medical definition for "Enoplida infections" as they are not a common or well-known type of infection in humans. If you have any concerns about a possible Enoplida infection, it is important to consult a healthcare professional for proper diagnosis and treatment.
28S ribosomal RNA (rRNA) is a component of the large subunit of the eukaryotic ribosome, which is the site of protein synthesis in the cell. The ribosome is composed of two subunits, one large and one small, that come together around an mRNA molecule to translate it into a protein.
The 28S rRNA is a type of rRNA that is found in the large subunit of the eukaryotic ribosome, along with the 5S and 5.8S rRNAs. Together, these rRNAs make up the structural framework of the ribosome and play a crucial role in the process of translation.
The 28S rRNA is synthesized in the nucleolus as a precursor RNA (pre-rRNA) that undergoes several processing steps, including cleavage and modification, to produce the mature 28S rRNA molecule. The length of the 28S rRNA varies between species, but it is typically around 4700-5000 nucleotides long in humans.
Abnormalities in the structure or function of the 28S rRNA can lead to defects in protein synthesis and have been implicated in various diseases, including cancer and neurological disorders.
