waterborne parasitic infections of the developed world

[Jacqueline Boyd]

Hi,
I am a fourth year parasitology student at the University of Aberdeen,
Scotland and am currently writing an essay with the above title.  I was
just wondering if i was covering all relevant infections if i cover -
Entamoeba histolytica, Giardia lamblia, Cryptosporidium.  There are
others i have considered- Balantidium coli etc, bu ti havent found much
literature regarding their effcts in water supplies within the developed
world.
I would be most grateful for any information anyone could give,
Thanks
Jackie
