The purpose of using RNA FISH is to detect target mRNA transcripts in cells, tissue sections, or even whole-mounts. [10] The process is done in 3 main procedures: tissue preparation (pre-hybridization), hybridization, and washing (post-hybridization). The tissue preparation starts by collecting the appropriate tissue sections to perform RNA FISH.
These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Isopod fish parasites are mostly external and feed on blood. The larvae of the Gnathiidae family and adult cymothoidids have piercing and sucking mouthparts and clawed limbs adapted for clinging onto their hosts. [20] [21] Cymothoa exigua is a parasite of various marine fish. It causes the tongue of the fish to atrophy and takes its place in ...
Parasite identity can also be confirmed using polymerase chain reaction to amplify the 415 base pair 18S rRNA gene from M. cerebralis. Fish should be screened at the life stage most susceptible to the parasites, with particular focus on fish in aquaculture units.

Flow-FISH was first published in 1998 by Rufer et al. [11] as a modification of another technique for analyzing telomere length, Q-FISH, that employs peptide nucleic acid probes [12] of a 3'-CCCTAACCCTAACCCTAA-5' sequence labeled with a fluorescin fluorophore to stain telomeric repeats on prepared metaphase spreads of cells that have been treated with colcemid, hypotonic shock, and fixation to ...
Kinetoplastida (or Kinetoplastea, as a class) is a group of flagellated protists belonging to the phylum Euglenozoa, [3] [4] and characterised by the presence of a distinctive organelle called the kinetoplast (hence the name), a granule containing a large mass of DNA.
The infected fish also becomes lethargic, swims near the surface, and its appetite decreases. [10] Additionally the infected fish may hold its gill covers open and scratch its gills on rocks. [14] In severe infections, Dactylogyrus species can cause hemorrhaging and metaplasia of the gills which can lead to secondary bacterial infections and ...
