The Foot-and-Mouth Disease Virus (FMDV), Serotype O, is the primary etiological agent of Foot-and-Mouth Disease, a highly contagious viral illness that affects cloven-hoofed animals, especially cattle, swine, sheep, and goats. It is one of the diseases with the greatest sanitary and economic impact on the global livestock industry, due to its rapid spread and the severe trade restrictions associated with its occurrence.
FMDV belongs to the genus Aphthovirus, family Picornaviridae, and has several antigenically distinct serotypes, with serotype O being the most widely distributed globally. Infection occurs primarily through direct contact between susceptible animals, aerosols, secretions, excretions, fomites, and contaminated animal-derived products.
Clinically, Foot-and-Mouth Disease is characterized by fever, intense salivation, lameness, and the formation of vesicles (aphthae) in the oral cavity, tongue, lips, nostrils, udder, and the interdigital region. In young animals, particularly calves, high mortality rates may occur due to cardiac lesions, even in the absence of classic signs.
The control of Foot-and-Mouth Disease is based on rigorous biosecurity measures, epidemiological surveillance, and official vaccination programs, where applicable. Immediate reporting of suspected cases is mandatory, as it is essential for the rapid containment of outbreaks and for maintaining the sanitary status of producing regions.
Laboratory testing plays a central role in the surveillance and diagnosis of Foot-and-Mouth Disease. Molecular methods, such as real-time PCR, allow for the rapid and sensitive detection of the viral genome, as well as the differentiation of serotypes, including serotype O. These tools are essential for diagnostic confirmation, monitoring viral circulation, and supporting eradication efforts.
Continuous surveillance, coupled with accurate laboratory diagnosis and official sanitary strategies, is fundamental to prevent the reintroduction of Foot-and-Mouth Disease Virus serotype O, protect animal health, and ensure the sustainability and competitiveness of the livestock production chain.

In this context, the Bioperfectus Foot-and-Mouth Disease – FMDV Serotype O rapid test serves as a strategic screening tool to support sanitary surveillance and provide a rapid response to clinical suspicions. The application of this rapid test enables the agile identification of suspected animals directly in the field, on rural properties, or at sanitary control points, allowing for the immediate adoption of containment measures such as isolation, animal movement restrictions, and notification to official veterinary services. Thus, the rapid test complements confirmatory laboratory methods, contributing to the early detection of outbreaks, the reduction of FMDV Serotype O spread, and the strengthening of Foot-and-Mouth Disease control and eradication efforts.
