ABSTRACT. A survey on the presence of
Cryptosporidium oocyst and Giardia cyst in livestock
drinking water as well as the urban tap water throughout Taiwan
was carried out. Water examination for the presence of the
protozoa was conducted by filtering through a PTFE membrane
followed by immunomagnetic separation (IMS) and immunostaining
the sediment with commercially available monoclonal antibody
against Cryptosporidium and Giardia. Of the 55
different water samples from various sources examined, 2 were
found to contain both of Cryptosporidium oocyst and
Giardia cyst, 1 was found to contain Cryptosporidium
oocyst only. These protozoa-positive water samples, originating
from underground well and from the mountain spring, were also
used as drinking water for livestock. However, no
Cryptosporidium oocyst was found in the city tap water. This
is the first report of Cryptosporidium oocyst and
Giardia cyst being found in the drinking water for
livestock.
