Objective. The aim of the present study was to determine the efficacy of Chloroquine (Cq), an antimalarial medicine, administered at a dose of 2.5 mg/kg, orally, during 5 consecutive days, in Sakiz and Merino lambs naturally infected with Giardia duodenalis. Materials and methods. To this extent weaned 10 weeks of aged lambs were enrolled and randomly assigned into two groups based on treatment (group C, n=18 lambs treated with Cq) and placebo (group P, n=8 untreated control animals). Diagnosis was based on detection of trophozoit and/or cysts on fecal flotation. Cyst count per gram feces (days 0, 3, 7 and 10) was analyzed among groups. Results. During the trial, regarding the efficacy of Cq on days 3., 7., and 10. There was significant (p<0.01) reduction in cyst excretion; whereas evaluation of mean geometric cyst excretion revealed 100% reduction. Conclusions. There was a very high (100%) reduction in cyst excretion in the Cq treatment group compared to the positive untreated control group on days 3, 7 and 10, resulting in a significant (p<0.001) reduction, making Cq, safety, and thus highly effective treatment option of lambs with naturally occuring giardiasis.

Objetivo. El objetivo del presente estudio fue determinar la eficacia de la cloroquina, un medicamento contra la malaria, administrado a una dosis de 2.5 mg/kg, por vía oral, durante 5 días consecutivos, en Corderos Sakiz y Merino infectados naturalmente con Giardia duodenalis. Materiales y metodos. En esta medida destetados 10 semanas de edad fueron incluidos y asignados al azar en dos grupos sobre la base del tratamiento (grupo C, n = 18 corderos tratados con cloroquina) y placebo (grupo P, n = 8 animales de control no tratados). El diagnóstico se basa en la detección de trophozoit y/o quistes en la flotación fecal. Quiste recuento por gramo de heces (día 0, 3, 7 y 10) se analizó entre los grupos. Resultados. Respecto a la eficacia de la cloroquina en los días 3, 7 y 10 existió una reducción significativa (p<0.01) en la excreción de quistes; mientras que la evaluación de la media de la excreción Rev.MVZ Córdoba 21(2):5328-5335, 2016. ISSN: 0122-0268 ORIGINAL 5329 de quistes reveló una reducción del 100%. Conclusiones. Durante el estudio hubo una reducción del 100% en la excreción de quistes en el grupo de tratamiento con cloroquina en comparación con el grupo control no tratado positivo en los días 3, 7 y 10, lo que resulta en una disminución significativa (p<0.001) por lo que la cloroquina razonablemente es una opción de tratamiento por el costo, seguridad, y por lo tanto muy eficaz de corderos infectados naturalmente con giardiasis.
