Abstract
ABSTRACTAn enzyme-linked immunosorbent assay (ELISA) was developed to detect bovine antibodies to Histophilus somniexopolysaccharide (EPS), which is created during biofilm formation. When an index value of 0.268 was used, the sensitivity of the assay for infected calves was 90.5% at 3 weeks postinfection, but the number of positive animals increased by week 4. The specificity of the assay for healthy calves was 92.5%. The EPS ELISA may aid in identifying calves with H. somnidiseases.
