Pathogen Detection and Reagents

Dairy One has the ability to produce reagents for detecting different types of mastitis. Our labs can produce these reagents for other labs to use, dairy farmers to use on-site at their farms, or can test samples submitted to our Ithaca laboratories.

Pathogen Creation for Laboratories

Polymerase Chain Reaction (PCR) is a fast technique to amplify small segments of DNA in a sample. Specific small segments of DNA can be used to fingerprint the bacteria in a milk sample. This reaction can detect the DNA from both live and dead bacteria. Dairy One can produce PCR reagents that other laboratories can use for their testing services. Through the DevOps team at Dairy One, laboratories can also receive software support for their lab testing and technology.

On-Farm Pathogen Detection

Acu-POLARIS is an easy-to-use testing system that detects mastitis-causing pathogens in as little as three hours. Using this system, farmers can begin to control contagious mastitis and reduce somatic cell counts.

This system includes a thermocycler and software for farms to analyze samples collected at their location.

There are five pathogens tests that can be run on this system:

  • STREP – Streptococcus uberis and Streptococcus spp
  • STAPH – Staphylococcus aureus and Staphylococcus spp
  • MYPRO – Mycoplasma spp and Prototheca spp
  • SASUB – Staphylococcus aureus and Streptococcus uberis
  • MYCOB – Mycoplasma bovis

Sample Testing for Farms

Using a milk sample, Dairy One can test for the presence of Mycoplasma bovis. Samples can be collected by farms or on a test day conducted by a DHI Field Technician. A single milk sample can be tested for multiple things aside from Mycoplasma bovis, including component levels, if a cow is pregnant, and the presence of Bovine Viral Diarrhea or Johne’s Disease.
