A. Joachim et al., Identification, isolation, and characterization of a species-specific 30-kDa antigen of Oesophagostomum dentatum, PARASIT RES, 85(4), 1999, pp. 307-311
In the search for a serology tool for the diagnosis of nonpatent as well as
patent infections with Oesophagostomum dentatum in pigs a water-soluble, u
nglycosilated antigen of about 30 kDa specific for the third-stage larvae o
f the parasite was purified by ion-exchange chromatography. In Western blot
s, the antigen was first detected by antibodies at day 7 postinfection. Cro
ss-reactivity with O. quadrispinulatum, Ascaris suum, or Trichuris suis was
not detected. It is suggested that this protein is a suitable tool for the
species-specific serodiagnosis of O. dentatum infection in pigs.
