Size up to 1mm = to 1,000 microns aka um`s and subsequently capable of being captured via an RDF screen during the vacating the host stage prior to encysting in situ ...

Note the `Characteristic` Horseshoe shaped Macronucleus is not always visible microscopically.

We found whitespot yesterday. Having seen your video, I think we saw it two weeks ago and mistook it for tric. We treated with PP for tric, still having problems so a scrape last night revealed whitespot on the scope. There were quite a few but moving slowly, two weeks ago, they were darting about as in your video.

We have treated with F & M but as we are away next week it will be difficult to retreat on day 7. I am now thinking of returning home next Tuesday for the day to retreat and check all is well.

Alan my poor video clips are of Tetrahymena...

Whitespot moves much more slowly as in this clip > http://www.videosurf.com/video/ich-115980329

And the clip in the first post on this thread.

What temps are your Koi at ?

Hi Mio, no sulkers today although they move slowly with dorsal fins clamped. The water temp has dropped from 19 to 16 so that may make them a bit miserable. The majority are OK though.

I did one treatment on Tuesday and unless I am told not to, I will treat again Saturday morning after doing a 20% water change.

The Parasite temp range for ICH during (epizootics) outbreaks tends to erupt at 14C and above .... hence usually in Spring.

At 20C full maturity of Trophonts/Trophozoites takes approx one week whereas 20 days are required at 7C...

Were you not going on holiday Alan I would have recommended hiking the Temp up to increase the Babes immune response and speed up the Parasite cycle....

Infected Koi will develop Immunity to this particular strain of ICH once the infection ceases ...which will protect them for a while.

Have your Gravid Females Spawned this year yet ? and are they and the sexually mature Males worse affected ?

No spawning this year, the two koi that we know are female seem to be unaffected. One large male has visible white spots that are not normally there.

We have one of our fry (1 year old now) that has been staying in the bottom of the pond. After PPing a couple of weeks ago, it was bent and struggling. I netted it today and took a scrape. I found nothing on the slide except a dead body fluke. The fish was badly bend and had 3 lesions on its underside. I guess I may have hit it with the net when trying to catch another fish when PP was in the water and clarity was minimal.

I have given it and overdose of Clove of olives as I cannot keep an eye on it over the next week and it was really struggling to swim.

How Sad Sweetie Sad

It`s quite a common occurrence sadly Alan .. I know another Member who has had to euthanize 2 or 3 due to broken backs...

On all occasions Parasites were being treated causing the Babes to Flick/Flash and jump injuring the fry.

How is the large sexually mature Male Koi Babe now Alan ? re the `White-Spots`? And did they infect his eyes too ? which they frequently do !

The Mature ICH Trophont/Trophozoite following eruption from the protective calcified mucous coating the Koi Babes immune system naturally tries to `encase` the Parasite in protects it from any and all attempts to eradicate it treatment wise until it leaves the host whereupon the cilia is lost prior to encystment ...

This stage swims very awkwardly as it falls to the bottom of the pond so could quite feasibly be removed via a decent current flow into an RDF ..
