A new Polymerase Chain Reaction (PCR) test can rapidly detect Streptococcus suis serotype 7 in pigs. This diagnostic tool aids in controlling infections caused by this common swine pathogen.

Area of Science:

  • Veterinary Microbiology
  • Molecular Diagnostics
  • Bacteriology

Background:

  • Streptococcus suis is a significant swine pathogen.
  • Epidemiological studies identify serotype 7 as frequently associated with diseased pigs.
  • Current diagnostic methods for S. suis serotype 7 are lacking in speed and sensitivity, hindering control efforts.

Purpose of the Study:

  • To develop a rapid and sensitive diagnostic test for Streptococcus suis serotype 7.
  • To address the limitations of existing diagnostic approaches for this specific serotype.

Main Methods:

  • Development of a type-specific Polymerase Chain Reaction (PCR) assay.
  • Utilizing DNA sequences of capsular (cps) genes unique to S. suis serotype 7.
  • Identification of target sequences through cross-hybridization against 35 S. suis serotypes.

Main Results:

  • Successful development of a type-specific PCR test for S. suis serotype 7.
  • The PCR test demonstrates high sensitivity and specificity for detecting serotype 7.
  • The method is based on unique genetic markers of the serotype 7 capsule.

Conclusions:

  • The developed PCR test provides a rapid and sensitive diagnostic solution for S. suis serotype 7.
  • This advancement is expected to improve the prevention and control of S. suis infections in swine.
  • The availability of this diagnostic tool will aid veterinary professionals in managing swine diseases.
