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 />
