Abstract:
As seen by prior tragic outbreaks in many places throughout the world, the foot and mouth disease virus, or "FMDV," is one of the most critical challenges in animal health. In this review, the major features of FMDV, as well as aspects of its interactions with cells and hosts, were discussed. On the other hand, present and upcoming FMD treatment approaches. The first vertebrate virus found was the foot-and-mouth disease virus (FMDV). A capsid protein and the viral genome (+ve sense single strand RNA) make up FMDV. The icosahedral symmetry of the viral structure is made up of structural proteins (VP1, VP2, VP3, and VP4) as well as non-structural proteins (L, 1A, 1B, 1C, 1D, 2A, 2B, 2C, 3A, 3B, 3C, and 3D). The viral replication takes place in the cytoplasm of the cell. Because FMDV has a short incubation period, it spreads quickly. Direct contact is the most often used method of FMDV transmission. The occurrence of direct contact via aerosol and mechanical transmission (fomites, feed, and water). The immunological response is stimulated by the infection with FMD. However, due to virus antigenic diversity, the immune response does not always protect against FMD (antigenic shift). FMDV is divided into seven serotypes based on antigenic variation. O, A, C, SAT-1, SAT-2, SAT-3, and Asia-1 are the serotypes in question. O is the most frequent serotype.
