Abstract

  Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals and wild ruminants. It is caused by the foot-and-mouth disease virus (FMDV). Due to the contagiousness and aerosol transfer of FMDV, not all labs can handle FMDV. Only labs equipped with proper biocontainment facility (BSL3) can handle the work related to live FMDV. This may create hindrance in the expedition of sample testing by virus isolation. Thus, it is imperative to make the existing BSL-2 labs competent for testing the FMDV infected samples. Real-time PCR is one of the rapid ways of testing FMDV infected samples. Positive control of FMDV RNA is required for performing this assay. However, due to biosecurity reasons live FMDV cannot be used in BSL-2 labs. Therefore, one of the ways of obtaining FMDV RNA is extracting FMDV RNA from FMDV inactivated vaccine for its subsequent use in real-time PCR. In this work, we have extracted the FMDV RNA from inactivated FMDV vaccine and have subsequently used it as a positive control for screening oro-pharyngeal fluid from field animals (buffaloes) to confirm the FMDV carrier state. This work explores new opportunities to strengthen existing BSL -2 labs for testing the FMDV infected samples without virus isolation.
