In farms with a clinical or even a latent infection, the disease is identified by isolating the pathogen. Since Salmonella bacteria are not shed continuously, the most suitable method for this is the testing of several pooled faecal samples obtained from different pens. The herd can also be screened by collecting swipe samples from the floor and surroundings in order to identify introduction routes and areas in the pig houses with particularly high pathogen burdens.
Methods that can be additionally used to test sow farms for Salmonella include serological antibody detection or bacteriological detection in the ileocaecal lymph nodes.
The new PCR kit offers some key advantages compared to the classic microbiological approach
- Time: after an enrichment step (required for any analysis), differentiation will only take about 2 hours, instead of up to 5 days
- Matrices: the PCR can be performed from bacterial culture material, or directly from samples (swabs, boot socks, enrichment step required)
- Information: in addition to the reliable differentiation of the vaccine from field strains, the kit also identifies if a field strain is S. Typhimurium or S. spp
