Collecting and Submitting Swine Samples for Diagnosis
Selection and Collection of Tissues/Samples
- Samples for detection (bacterial culture, virus isolation, or PCR) of the pathogen should be fresh (refrigerated). Fresh tissue samples should be sufficiently large to allow culture; do not cut loops of intestines open. They may be placed separately in Ziploc® or Whirl-pak® bags.
- Formalin-fixed samples should be kept separate from fresh samples.
- Intestinal samples should be at least two inches in length. These samples should be kept separate from other samples to avoid contamination.
- If using culture swabs and transport media, be sure to use the appropriate media:
- For mycoplasma or viral isolation, always use the recommended medium.
- For bacterial isolation, avoid using mycoplasma or viral media which contain antimicrobials and may inhibit growth of the desired pathogen.
- All samples should be "double-bagged" to reduce the chance of leaking. This includes formalin-fixed samples.
- All samples (unless noted otherwise) should be refrigerated until shipped. For shipping, choose the method that will assure samples will be received in 48 hours or less. Avoid sending tissues over a weekend. Appropriate amounts of ice (cold packs) should be used. In hot weather, additional ice packs should be included.
- Free diagnostic shippers are available upon request.
