Figure 3

Optical density (OD) variations in ELISA Serum-specific IgG response using adult H. contortus antigenic extract in naturally infected goats, treated with doramectin and CP extract. Optical densities were measured by ELISA at 450 nm. Significant differences are indicated by an asterisk marks ( ). G1: negative control (untreated); G2: positive control (treated with doramectin, 1 mL/50 Kg b.w.); G3 and G4: animals treated with 2.5 and 5 mg/Kg of CP extract, respectively.
