9 December 2015 (Wednesday) - Typanosomes

In the most recent parasitology NEQAS survey was a thick film for examination. I didn’t see any parasites in it; nor did any of my colleagues.

It turned out we were all wrong; there were actually trypanosomes in that film. I reviewed the film with a colleague and knowing that there were trypanosomes present they were eventually identified.
However on reflection they weren’t obvious. I can’t help but feel that thick films are a rather artificial preparation. A Google search found recommendation of reviewing buffy coat preparations rather than thick films. If nothing else they are more familiar in appearance.

The next time we get a low parasitaemia I shall make and stain a buffy coat preparation and see…
