Abstract
A microcapillary-based loop-mediated isothermal amplification (µcLAMP) has been described for specific detection of infectious reproductive pathogens in semen samples of cattle without sophisticated instrumentation. Brucella abortus, Leptospira interrogans serovar Pomona and bovine herpesvirus 1 (BoHV-1) cultures were mixed in bovine semen samples. The µcLAMP assay is portable, user-friendly, cost-effective, and suitable to be performed as a POC diagnostic test. We have demonstrated high sensitivity and specificity of µcLAMP for detection of Brucella, Leptospira, and BoHV-1 in bovine semen samples comparable to PCR and qPCR assays. Thus, µcLAMP would be a promising field-based test for monitoring various infectious pathogens in biological samples. Highlights Detect infectious organism in bovines semen Reduction in carryover contamination is an important attribute, which may reduce the false-positive reaction. µcLAMP is a miniaturized form, which could be performed with a minimum volume of reagents. The µcLAMP assay is portable, user-friendly, and suitable to be performed as a POC diagnostic test.
