Resumo
Phytotherapy is often used for parasitic diseases controlling in several animal species. This study aimed to evaluate the infective larvae (L3) of Ancylostoma spp. immersed in ethanol extract and Chenopodium ambrosioides L. essential oil in the in vitro test. It was used distilled water (negative control) and albendazole and commercial association of praziquantel, pyrantel pamoate and febantel (positive controls). The ethanol extract of C. ambrosioides L. at concentration of 0.5%, 1.0%, 2.0%, 3.0%, 4.0%, 5.0%, 6.0%, 8.0%, 10.0%, 12.0 % and 20% had insufficient activity to the larvicidal effect. The essential oil at concentration of 150µL.mL-1 was effective against L3. The formulation of a biscuit manipulated with a concentration of 37,5 µL.g-1 of the C. ambrosioides L essential oil reduced the number of eggs per gram of the dogs feces. Twenty-six adult dogs were divided into three groups for in vivo testing: F1 (biscuit without active ingredient), F2 (biscuit with C. ambrosioides L. active principle), F3 (biscuit with allopathic active ingredient). At the CBC, there were significant differences in F1 for values of red blood cells, hematocrit and mean corpuscular hemoglobin concentration (MCHC) and albumin in serum biochemistry. The F2 showed difference in MCHC and in biochemical the serum protein and globulin. The F3, lymphocytes and monocytes values in the blood count and albumin and globulin were different between M1 and M2. At the parasitological exam F1 remained parasitized, while the F2 reduced significantly the infection and F3 showed negative result in M2. It is concluded that the formulation of a biscuit manipulated with C. ambrosioides L essential oil reduced the Ancylostoma spp. infection in naturally infected dogs
