From: Hunting dogs as sentinel animals for monitoring infections with Trichinella spp. in wildlife
Assay validation study: optical density and cut-off values of dog/fox serum samples by ELISA. Serum samples from presumably Trichinella spp.-free (n = 598) and Trichinella spp.-infected (n = 21) dogs/foxes were tested by ELISA using Trichinella spiralis and Toxocara canis excretory/secretory antigens. Out of the 619 sera, 47 tested positive for T. spiralis; of these, 26 sera from presumably Trichinella spp.-free dogs tested negative by Western blot (Wb), and 21 sera from Trichinella spp.-infected dogs/foxes tested positive by Wb (see Table 1). Out of the 619 sera, 233 (37.6 %) tested positive by ELISA for T. canis (see Table 1)
