We think that the somatic antigen derived from nematodes L4 stage induces the immune response to Th1-mediated diseases.
Haemonchus and Trichuris positive samples, based on coprological examination indicated 100% positive sensitivity for each genus of nematode by the ELISA, based on crude somatic antigen, while based on excretory antigen, showed lower (92%) sensitivity.
The results revealed that the Haemonchus contortus and Trichuris ovis positive sera samples (200) based on coprological analysis were also indicated 100% positive sensitivity by the ELISA based on excretory- secretory antigen, while with crude somatic antigen based ELISA showed lower (92 %) sensitivity (Table 4).
This can be accounted for by the demonstrated high prevalence of Salmonella antibodies in local healthy population and the fact that 50% of the patients had detectable levels of antibodies to the somatic antigen (21,23,27).
