Curious amoeba
Its appearance resembles an amoeba standard except for a "filament" that come from within
What is the function of these?
I think it's Ouramveba

Hi Francisco,
there is no Ouramoeba as initially described by Leidy in 1879. It is an Amoeba proteus or a Trichamoeba sp. with a fungus infection, possibly by Amoebophilus forming all these bristles.
A rather rare finding - very interesting!

Hi Ernst:

Thanks for your information.
I base my identification on data located in this page:

http://www.xmission.com/~psneeley/Personal/Fwr09P.htm

Otherwise, I have no found too much information about these amoebas.
Last water cultures collected, I have found very much amoebas of this kind.

Best regards

Francisco

Francisco,
your link is exactly Leidy's publication I mentioned, with marvellous drawings - highly recommended in spite of being so old!
I wrote a paper concerning this infected amoeba in MIKROKOSMOS 2007/4 page 204, unfortunately in German. More literature is shown there.
Could you give more information about the site of your finding?
Regards Ernst.

So did the person who drew those pictures from observation not know what the spikes were caused by? I guess he would not, in those days. It sounds like he was just "report" what he saw and not speculating on the cause?

The poor guy in Franciscos video was having a really bad day. It didn't look healthy.

Thanks Ermst:
This sample comes from Albufera Natural Park (Valencia - Spain)
Particularly from some rice fields. At this time water is allowed to dry and there are small ponds with stagnant water, with a lot of pollution.
In these samples, I have seen large numbers of amoebae (about 50-100 every in a drop of water), many of them with the appearance you can see in the video.
Can I get your article in some link?
I try to gather as much information as I can from the micro stuff, and your article would be very interesting to me.
Cause some rafters in the amoeba that fungus?
Fungi are capable of causing extensive damage to even more complex animals:

Francisco,
if you give me your adress per PM, I would send a copy of my paper to you. Additionally much better photos were made by Martin Kreutz, whom you may contact: gastronauta@gmx.de
This Albufera Natural Park must be an eldorado!
Kind regards
