 Trichodina is one of the easiest protozoan parasites to detect under the microscope as
it is almost perfectly round with hundreds of hooks which resemble cilia found its periphery and it constantly rotates as it
moves through the mucus, causing tissues damage.
It attacks both skin and gill tissues of our Koi, and can often
cause more damage to gills than realized.
Classed as a warm water parasite, it can survive for some time without a
host. It causes vegetation of the skin giving rise to a grey white opaque appearance on the body of infected Koi which
exhibit the classic symptoms of flashing, rubbing and lethargy.
A magnification of 100 to 200 x is required to
view this parasite.
Recommended treatments are Potassium Permanganate. |
