Sendai Virus (SeV) is a respiratory virus belonging to the genus Respirovirus, family Paramyxoviridae, widely used as an experimental model in biomedical research and also recognized as an infectious agent of importance in laboratory rodent colonies, especially mice and rats.
Sendai Virus infection occurs primarily through the respiratory route, via the inhalation of contaminated aerosols or direct contact with respiratory secretions. The virus exhibits high transmissibility, particularly in environments with high population density and inadequate ventilation.
From a clinical standpoint, Sendai Virus is associated with respiratory infections ranging from subclinical forms to more severe manifestations, including rhinitis, bronchitis, and pneumonia. Young, immunosuppressed, or stressed animals are at a higher risk of severe clinical progression.
In laboratory animal colonies, Sendai Virus infection can significantly interfere with experimental results, as it causes immunological and physiological changes in infected animals. Therefore, rigorous sanitary control is essential to ensure the reliability of scientific studies.
Prevention and control measures include rigorous biosecurity practices, periodic sanitary monitoring, quarantine of newly introduced animals, and the elimination of positive individuals, when indicated. Currently, there is no specific effective treatment, making sanitary management the primary control strategy.
Laboratory testing plays a fundamental role in the epidemiological surveillance of Sendai Virus. Serological and molecular methods, such as real-time PCR, allow for the early detection of the agent, enabling the rapid adoption of corrective measures to prevent the dissemination of the virus within colonies.
Thus, continuous surveillance, combined with precise laboratory diagnosis and good management and biosecurity practices, is indispensable for the control of Sendai Virus, ensuring animal health and the quality of results in research environments and vivariums.
In this context, the Bioperfectus Sendai Virus (SeV) rapid test serves as a practical screening tool to support sanitary monitoring in rodent colonies and vivariums. The use of the rapid test allows for the agile identification of suspect animals directly within the sanitary control routine, aiding in the immediate adoption of measures such as quarantine, segregation, or sanitary disposal prior to confirmation by molecular laboratory methods. In this way, the rapid test complements conventional diagnostic techniques, contributing to the early detection of infection, the prevention of SeV dissemination, and the maintenance of sanitary quality and the reliability of experimental results.
