DNA-based methods have emerged as an additional tool for Brucella infection-confirmation at a herd level. However, their implementation may require the use of specialized equipment. In this context the recently developed loop-mediated isothermal amplification (LAMP) technique may constitute an additional and cost-effective tool for rapid and specific DNA detection, especially in low income areas. In the present study the usefulness of a newly developed LAMP assay aiming at the multicopy-IS711 sequence was assessed on a variety of clinical samples (n = 81 from abortions and ewes; cattle, n = 3; swine, n = 4) that were analyzed in parallel using real-time PCR and bacteriology. Although overall sensitivities obtained with the three methods were comparable (p > 0.05), our results highlighted the complementarity between bacteriology and molecular-based methods for increased sensitivity. Significant differences (p < 0.05) were observed with all techniques depending on the nature of the sample. Our results demonstrate the potential of the IS711-LAMP technique for direct Brucella detection.
