ABSTRACT<br />
DETECTION OF CRYPTOSPORIDIUM OOCYSTS IN THE WATER TREATMENT RESIDUAL<br />
PLANT OF TAIGUAIGUAY, ESTADO ARAGUA, VENEzUELA<br />
Cryptosporidiosis is a gastrointestinal parasitic disease of man and animals caused by a opport<strong>un</strong>istic<br />
protozoan called Cryptosporidium. It is a zoonosis that can be acquired through human and animal feces. The<br />
infective stage is the oocyst, which is resistant to adverse conditions in the environment. In Latin America<br />
there is an increase of mortality due to high prevalence in patients infected with Human Imm<strong>un</strong>o<strong>de</strong>ficiency<br />
Virus (HIV). In the present investigation was assessed by The presence of Cryptosporidium in the water<br />
treatment plant residual Taiguaiguay Venezuelan Aragua State was assessed by direct imm<strong>un</strong>ofluorescence<br />
(DIF). We analyzed 14 samples of water (7 at the entrance and 7 in the output of the water treatment plant)<br />
resulting 57% of the samples collected at the entrance of the plant contaminated with Cryptosporidium<br />
oocysts and 43% at the start, with an overall average of 50% of contaminated water with oocysts (maximum<br />
and minimum values fo<strong>un</strong>d in the input were 16 Ooq / L and 4 Ooq / L at the output of 6Ooq / L and 3 Ooq<br />
/ L), representing a risk level for human consumption.<br />
Key words: Wastewater, Cryptosporidium spp, direct imm<strong>un</strong>ofluorescence (DIF).<br />
RESUMEN<br />
La criptosporidiosis es <strong>un</strong>a enfermedad parasitaria gastrointestinal <strong>de</strong>l hombre y <strong>de</strong> los animales causada<br />

<strong>de</strong> heces <strong>de</strong> animales y humanos, El ooquiste es el estadio infectivo, resistente a condiciones adversas en el<br />
medio ambiente. En Latinoamérica existe <strong>un</strong> incremento <strong>de</strong> morbimortalidad <strong>de</strong>bido a <strong>un</strong>a alta prevalencia<br />
en pacientes infectados por el Virus <strong>de</strong> Inm<strong>un</strong>o<strong>de</strong>ficiencia Humana (VIH). En la presente trabajo se evaluó<br />
