Development of Rapid Isothermal Detection Methods Real‐Time Fluorescence and Lateral Flow Reverse Transcription Recombinase‐Aided Amplification Assay for Bovine Coronavirus

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Bovine coronavirus (BCoV) is a notable pathogen affecting newly born calves and adult cattle, increasing mortality rates among calves and reducing productivity in meat and dairy industries, thereby causing substantial economic losses. Current primary laboratory methods for detecting BCoV include RT‐PCR assay, real‐time RT‐PCR assay, and ELISA. However,
