Key result
Seven different RT-qPCR methods for detecting FMDV demonstrated similar sensitivity and specificity, though noticeable distinctions emerged in samples with low RNA concentration.
Why the study?
Prompt and accurate diagnosis of foot-and-mouth disease outbreaks is critical to curb rapid transmission, prompting a comparative analysis of different RT-qPCR methods for FMDV detection.
Do different RT-qPCR methods perform similarly in detecting Foot-and-Mouth disease virus?
Do different RT-qPCR methods perform similarly in detecting Foot-and-Mouth disease virus?
Various RT-qPCR methods for FMDV detection perform similarly for high-concentration samples but show variations when RNA copies are low.
RT-qPCR methods show similar FMDV performance; leaves open optimal assay selection for varied samples.
The prompt and accurate diagnosis of foot-and-mouth disease outbreaks is crucial to curb the swift transmission of its causative agent, the foot-and-mouth disease virus (FMDV), which poses a substantial threat to the nation’s livestock. This study aimed to perform a comparative analysis of various RT-qPCR methods for the detection of FMDV. The methods evaluated for the 3D region demonstrated similar sensitivity and specificity. Nevertheless, noticeable distinctions emerged in samples with low RNA concentration. While these methods can be interchangeably utilized with consistent outcomes when handling a large number of samples sent to the laboratory to pinpoint an outbreak, minor variations may assume significance when working with a limited quantity of samples containing low FMDV RNA copies.
