I'm trying to find out more info about this parasite... can't seem to find barely anything on it?

thanks
 
Noga (2000) has some details about Uronema, including a number of references in the scientific literature.

What particularly are you trying to find out?

ATJ...I first have to tell you that I love your avatar! Is this you?
I was reading your message and then thought I saw something move and would look at the picture and then think...ummm must be imagining something, then back to reading and then thought that I saw something move again and look over...nothing...finally after watching you close...I realized your eyes were moving!!LOL too cute!
I'm just curious about this parasite. A friend of mines fish might have had it....but I couldn't help her out at the time, as I couldn't find anything on it. Although they seem to mention the name along with ich and velvet, they don't tell you much about it? Is it also a parasite in which needs a host? how long is it's life cycle? etc. Just like to know more about it for my own satisfaction.
thank you
 
chicki,
I have had limited sucess treating this ciliate with copper. Copper was only slightly effective if the concentration was more than .2 ppm. Oddly enough, I have found that treating with a product called Ick Gaurd knocks the Uronema populations back. Ick Guard is made by Jungle and it is only supposed to be used for freshwater but it worked in saltwater. As for an active ingreadient I can't remember, you will probably have to call the company.

Chicki,

Yeah, it's me.

According to Noga (2000), Uronema is a free-living protozoa and can survive without fish. There is no discussion on the life cycle so I can't comment. He also says that it can cause internal infections in addition to external lesions. Recommended treatment is a freshwater bath followed 24 hours later by prolonged formalin treatment (0.06 to 0.09 mL of formalin per gallon) which should only be performed in a treatment tank.
 
thanks!

ummm...so it could live in a fishless tank indefinitely??? would you know what the "normal or usual" protazoan" life span is? You say he mentions internal infections...would this be the parasite that is known to attack the brain??

thanks again
 
chicki,
Uronema reproduce asexually. This means by binary fission, so it only takes one Uronema to make many. From my experience one of two conditions have to be present to have the population of Uronema explode in your tank, which results in them attacking your fish. One, a more than normal accumulation of solid organic waste ( uneaten food, dead organism underneath a rock ect...). Secondly, damage to your fish from another organism ( fish on fish aggression, fungal disease ect..). Hope this helps.

Chicki,

Noga (2000) lists Muscle, kidney, liver, spinal cord and urinary bladder as sites of infection. Seeing as spinal cord is one site, I don's see why it couldn't infect the brain.
 
thanks and of course it helps! sounds like you've seen this on a first hand basis?
can you describe to me what it looks like in the different stages?
are you saying that it can develop on it's own for the reasons you stated? without it being brought in from another source?
do you have any idea how long the life cycle might be in a fishless tank?
thanks again, really appreciate all the info I can get
 
This discussion seems to concentrate on the treatment of an infected fish. How is it eliminated from the entire tank? As we know there are swimming stages of Amyloodinium or Cryptocaryon that are killed off in their free swimming stage with copper. How about this one that doesn't even need a host. What is the reason it may not infect other fish.
Am I missing something, or is it eliminated by killing it off the infected fish. That would indicate that if the infected fish is cured, there aren’t any left in the tank.
