Surface Reactivity Patterns Amongst Strongylid Nematodes Using immuno peroxidase Assay

Surface-reactivity amongst strongylid nematodes viz., Haemonchus contortus, Oesophagostomum columbianum and Bunostomum trigonocephalum was evaluated by immunoperoxidase test. In this assay, third stage larvae of H. contortus was used as antigen source in the interface of heterologous sera of O. columbianum and B. trigonocephalum. A strong and intense surface reactivity was observed with homologous sera whereas mild and less intense surface reactivity was observed with the heterologous sera.
