Is Trichodina a protozoa?
Trichodina spp. are ciliated protozoa known to colonize many species of amphibians and fish. These protozoa frequently inhabit the skin and gills, but may also be present in the urinary bladder of infected animals.
How to cure Trichodina?
Oodinium, Trichodina, and other external protozoa can be treated with salt baths (10–25 mg/l SID for 5–30 min) or acriflavin baths (constant 0.025% bath for 5 days).
Where does Trichodina come from?
Trichodinids are typically found on the gills, skin and fins of fishes, though some species parasitise the urogenital system. A range of invertebrates is also host to trichodinid infections, including the surfaces of copepods and the mantle cavity of molluscs.
Is Epistylis a parasite?
11.6. Groups of Epistylis form a colony (Figure 11.11). These parasites cause irritation and inflammation of the epithelium of the host at the point of attachment which may provide a site for secondary infections of Aeromonas hydrophila.
What is Trichodina Pediculus?
Trichodina pediculus is a mobiline peri- trichous ciliate living on the surface of freshwater hydrozoa. Ehrenberg (1838) de- scribed this organism in his book “Die In- fusionsthierchen als vollkommene Orga- nismen” and called it the “Polypenlaus” (louse of polyps).
What is formalin in fish?

How do fish get white spot disease?
White spot is a contagious parasitic disease of fish. Caused by Ichyophthirius multifilis, the parasite infects the fish after moving from the bottom of the pond. The parasite attaches itself to the fish, moving under the skin where it feeds on cells and body fluids.

Where can Trichodina spp.be found in fish?
Trichodina spp. typically target the gills, skin and fins of fishes, though some species parasitize the urogenital system. A range of invertebrates are also host to trichodinid infections, including the surfaces of copepods and the mantle cavity of molluscs and snails.
Can a fish recover from Trichodina without treatment?
Fish are typically resistant to Trichodina when provided a low stress environment, good water quality and a nutritious diet. Fish may recover without treatment when provided with improved water conditions.
How are trichodinas spread from host to host?
Trichodina species reproduce by simple binary fission. Most species are host specific and presumably spread from fish to fish by incidental contact between susceptible host fish, as well as through contact with the organism in the water column. Infected fish may ‘flash’ in an attempt to scratch off the organisms.
What is the schematic drawing of Trichodina Magna?
A. Schematic drawing of denticles of Trichodina magna to illustrate the sequence and method of the description of denticle elements, according to the method of Van As and Basson (1989). B. Diagnostically important features in the adhesive disc of trichodinids.
