Foot and mouth disease (FMD) is an acute, contagious viral disease that affects cloven-hooved domestic animals as well as over 70 wild life species such as elephants, deer etc. Symptoms of the disease include pyrexia, lameness, and vesicular lesions of the tongue, feet, muzzle, and teats [9]. Following a subset of the acute phase of infection, 50- 60% of the bovine population becomes a carrier or is persistently infected with FMD virus (FMDV). A carrier animal is one from which infectious FMDV virus [10] or genome detection [6] can be recovered 28 days after FMDV infection in the oropharyngeal fluid (OPF). FMDV persistence varies by species [2] and can occur in both vaccinated and unvaccinated animals [1]. Few researchers have previously reported that FMDV can be transmitted from carrier animals to susceptible naive populations under field conditions [8] or experimental conditions [5] and this could be due to the presence of infectious FMDV in oropharyngeal fluid of seemingly healthy animals [4,7].
