coli has a complex structure, and has the regional difference and diversity;
somatic antigen (O) is the major antigen and until now 173 kinds of antigens are identified in E.
In any case, little is thought about the basic mechanisms of the caring effect of somatic antigen derived from L4 H.
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).
coli strains were then subjected to serological testing using ProlexTM Latex agglutination kit for detection of
somatic antigen i.e.
repens
somatic antigen (p=0.001) than controls (Figure 2).
Somatic antigens are associated with the bacterial cell.
In this study, we identified multidrug-resistant EAEC isolates belonging to ST38; the isolates had various
somatic antigens and [bla.sub.CTX-M] genes (Table).
Meanwhile the use of
somatic antigens, prepared from adult worm, was not successful in vaccination [18,11].
Identification of Salmonella enterica serotypes is based on flagellar and
somatic antigens. Of the 2,610 serotypes distinguished in the Kauffmann-White-Le Minor Scheme (1,2), only Gallinarum are obligatory nonflagellate and hence, nonmotile.
