Contagious 3 PCR detects contagious organisms M. bovis, Strep ag., and Staph aureus. Complete 16 PCR detects contagious and environmental organisms that cause over 95% of mastitis cases.
  • PCR detection effective on DHI or hand-stripped milk samples from treated, fresh or late lactation cows
  • Pool up to five samples for cost-effective screening. Split positive pools to test individual samples
  • Convenient testing strategies:
    • High SCC samples focus on cows most likely to be positive
    • Fresh cows to optimize detection and minimize herd impact
    • Hospital pen to monitor infection status and verify clearance before reintroduction
    • Bulk tank or groups to provide ongoing surveillance
