PCR for Cryptosporidium detection?

Dear bionetters,
	I'm doing a research proposal on a biological problem in a non-Western
country for a microbiology seminar.   I chose to address detection of
cryptosporidium in Costa Rica.  From one article I've read , Giardia cysts
have been detected with a cDNA probe.  I imagine the same could be done
with Cryptosporidium oocysts, but I haven't found any published articles
(only immunoflourescence has been used).  Would a subunit of the 16s-like
rRNA be used, as in Giardia?  What gene specifically?  As a backup plan, I
will have the immunoassay method, but antibodies against what proteins?
	On a different but related topic, though I have two articles regarding
Cryptosporidium in Costa Rica, I would like to know what kind of water
treatment, if any, occurs in urban areas in that country and in urban areas
of other Central American countries.  I have statistics regarding diarrheal
agents, but not enough on water treatment.  It seems that urban Costa
Ricans would have better water treatment than their Central American
