The SVANOVIR O.ostertagi-Ab is a semi-quantitative ELISA enabling the detection and determination of exposure levels of Ostertagia ostertagi in grazing cattle. This assay was validated in an EU-wide project that tested a high number of herds from different European countries, and shows correlation between the exposure and antibody levels as well as the economic impact on milk yield caused by infection with O. ostertagi.

Features and benefits:

  • Diagnose O. ostertagi during and after infection through antibody detection, unlike conventional methods that require parasite detection in the sample
  • Support better decision making for prudent use of anthelmintics
  • Diagnose herds where O. ostertagi may be impacting milk production and improve milk output through appropriate anthelmintic control
  • Use one single bulk tank milk sample to determine infection severity, optimize commencement of the lactation curve and assess subsequent seasons
  • Produce test results in an easy-to-use-and-interpret format
