Rapid identification of porcine bacterial pathogens using an artificial intelligence Raman microbial analyzer for biology

Rapid and accurate identification of bacterial pathogens is critical for effective disease control in pig farms. Conventional bacterial culture-based and molecular diagnostic methods are time-consuming and often impractical for clinical decision-making. Raman spectroscopy, combined with artificial intelligence, offers a label-free alternative and provides isolate-level identification within approximately 2 min. The aim of this study was to evaluate the performance of the commercial Artificial Intelligent Raman M…

In brief

Researchers tested a commercial AI Raman analyzer on bacterial isolates taken from diseased pigs at a Taiwanese animal disease diagnostic center between March and November 2025. Species identities were first confirmed by PCR, and the device was then assessed against those reference labels.

The work matters because slow culture and molecular methods hinder clinical decisions on pig farms, where bacterial disease causes losses and some pathogens are zoonotic. What remains unclear is how well the tool performs beyond the tested isolates and for less common species, since the authors stress its value for common, important bacteria.

Main points

  1. The AIRMAB system performed well across all 14 clinically relevant swine bacterial pathogens tested.
  2. Pasteurella multocida (n = 30) and Salmonella Choleraesuis (n = 20) reached 100% recall in the test set.
  3. Escherichia coli recall was 97%, Streptococcus suis 94%, and Glaesserella parasuis 93%.
  4. The method is label-free and uses Raman spectroscopy with deep learning to give isolate-level identification.

The gain

An AI-assisted Raman system identified 14 clinically relevant pig pathogens with high recall, offering results in about 2 minutes per isolate for faster veterinary diagnostic decisions.

The rundown

Isolates were collected from various tissues of diseased pigs at the Animal Disease Diagnostic Center, National Pingtung University of Science and Technology, Taiwan. Species-specific PCR assays confirmed each isolate before Raman spectra were acquired, so the reference labels were reliable.

The authors contrast the system with conventional culture and PCR, which they describe as reliable but slow and dependent on well-equipped laboratories. They also compare it favorably with MALDI-TOF mass spectrometry, calling it highly automated and cost-effective.

They argue that rapid identification could support clinical intervention and large-scale screening, protecting both animal and public health, since several swine pathogens are zoonotic.
