The efficacy of chloroquine treatment against naturally occuring Giardia duodenalis infection in lambs
Journal Title: Revista MVZ Cordoba - Year 2016, Vol 21, Issue 2
Abstract
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.
