  The parasites I work on are called trypanosoma brucei – we call them tryps for short. They are about 30 micro-metres long. A micro-metre is a thousandth of a millimetre (the smallest markings usually on a ruler). So to see them swimming around I use a microscope with a 100X magnification. You get larger parasites like some worms that can grow quite long and live in your intestines – you can find some great videos of them swimming around inside someone’s intestine on youtube.
