Application of a loop-mediated isothermal amplification (LAMP) assay for molecular identification of Trueperella...

Area of Science:

• Microbiology
• Molecular Biology
• Veterinary Diagnostics

Background:

• Trueperella pyogenes is a significant opportunistic pathogen in both animals and humans.
• Accurate and rapid identification of T. pyogenes is crucial for effective treatment and disease control.
• Existing diagnostic methods can be time-consuming or require specialized laboratory infrastructure.

Purpose of the Study:

• To develop and validate a novel loop-mediated isothermal amplification (LAMP) assay for the identification of Trueperella pyogenes.
• To assess the specificity and reliability of the assay using various bacterial strains.
• To provide a low-cost and accessible diagnostic tool for T. pyogenes detection.

Main Methods:

• Design of a loop-mediated isothermal amplification (LAMP) assay targeting the cpn60 gene of Trueperella pyogenes.
• Isolation and culture of 28 Trueperella pyogenes strains from diverse sources.
• Testing the assay's specificity against control strains from related genera (Trueperella and Arcanobacterium).

Main Results:

• The newly designed cpn60 LAMP assay successfully identified all 28 tested Trueperella pyogenes strains.
• No cross-reactivity was observed with four species of the genus Trueperella and seven species of the closely related genus Arcanobacterium.
• The assay demonstrated high specificity and reliability for T. pyogenes detection.

Conclusions:

• The developed cpn60 LAMP assay offers a reliable and cost-effective method for identifying Trueperella pyogenes.
• This assay is particularly beneficial for laboratories with limited resources or specialized equipment.
• The findings support the potential of LAMP technology for rapid and accessible bacterial diagnostics.
