We have an unidentified pink flagellate we are trying to ID. It is from a water
sample from a pond near London. There are high numbers of bacteria in the
sample, a high concentration of this flagellate (which is actually turning the
water pink) and a few rotifers.
It appears to have no autofluorescence or chloroplast (under epi) but the outer
surface is a pink colour. Apparently the pond it was taken from smells of
garlic.
We wondered if it was a cryptomonad like chilomonas - but cant find much
about them being coloured.
It is elongated/ovoid with we think only 1 long flagella. It is very
symmetrical (sort of cigar shaped) and seems to be dividing bilaterally. It
approx. 20 - 100 microns in length. It is swimming very actively. Before we
dapi stained (and could then see the flagellum) it appeared to be more of a
cilliate type of movement because it was twisting.
It appears to be packed with granules, but we can't see a nucleus when we
DAPI stain it.
Has anyone seen this critter before? Pictures can be viewed on a website.
Any help would be appreciated.
Thanks
Karen
