A real-time PCR (RT-PCR) profile for the detection of Actinobacillus suis, Glaesserella (anc. Haemophilus) parasuis, Streptococcus suis, and Erysipelothrix rhusiopathiae is now available from Biovet.
As their names indicate, “suis-cides” diseases are life-threatening swine (“suis”) diseases (“cides”) caused by Actinobacillus suis, Glaesserella (anc. Haemophilus) parasuis, or Streptococcus suis.
Erysipelothrix rhusiopathiae can be related to this group of bacteria as it can also be fatal, especially in young animals.
Infections caused by these microbes are usually diagnosed by their laboratory isolation and the identification of isolates by the MALDI-TOF method.
In recent years, PCRs have been developed for each of these bacteria and allow them to be detected directly from various samples.
For some infections, PCRs have been shown to be much more sensitive and faster than culture. This is particularly true for meningitis caused by Glaesserella (anc. Haemophilus) parasuis.
At Biovet, we have developed a real-time PCR profile (RT-PCR) to detect these four microbes.
SUBMITTING SAMPLES (vary depending on conditions):
- Septicemia ( suis, A. suis, E. rhusiopathiae): filter organs such as the liver, kidney, spleen.
- rhusiopathiae (swine erysipelas): can also be skin biopsies.
- Pneumonia ( suis): the spleen.
- Meningitis ( suis, G. suis): meningeal swabs
- Polyserositis ( suis, G. suis): serous swabs and fluids from serous cavities.
Biovet will issue test results within 1 to 2 business days (after receiving samples).
These tests are performed Monday to Friday.
Each of these PCR tests is also available individually. To request these tests that are not on the form, indicate the name of the test in the Other Tests section.
