Popis: SUMMARYWestern blot analysis using an anti-globin rabbit serum Rb94 revealed a major band of 17 kDa in extracts ofOstertagia ostertagiadults and 4th-stage larvae. The adult stage globin-like antigen (OoAdGlb) was purified from total worm extracts by liquid chromatography. The protein has an estimated molecular mass of 36 kDa under non-reducing conditions, suggesting a dimeric structure containing 2 non-covalently linked 17 kDa monomers. Tryptic peptides were sequenced and showed strong similarities with the globins of free-living and parasitic nematodes. Immunolocalization revealed the presence of this globin-like antigen in the body wall musculature and/or the cuticle ofO. ostertagiadults. An enzyme-linked immunosorbent assay based on the purified OoAdGlb showed no differences in response between calves infected byO. ostertagiand/orCooperia oncophoraand the negative controls.
