Streptococcus suis is a bacterium of significant sanitary importance in the swine industry, recognized as one of the primary causative agents of infectious diseases in pigs. It is a Gram-positive coccus belonging to the genus Streptococcus, widely distributed in swine herds worldwide, with a significant impact on productivity and animal health.
Streptococcus suis possesses several serotypes, with Streptococcus suis type 2 considered the most virulent and most frequently associated with severe clinical conditions. In pigs, the infection can cause meningitis, septicemia, pneumonia, arthritis, endocarditis, and sudden death, especially in piglets during the nursery and growing phases. Asymptomatic carriers are common and play an important role in the maintenance and dissemination of the agent within herds.
Transmission occurs primarily through direct contact between infected and susceptible animals—via respiratory secretions, saliva, skin wounds, and mucous membranes—as well as through vertical transmission. Factors such as stress, high stocking density, management failures, co-infections, and unfavorable environmental conditions increase susceptibility to the disease.
Prevention and control of Streptococcus suis are based on the adoption of good management and biosecurity practices, population density control, reduction of stress factors, and constant sanitary monitoring. In some cases, the use of autogenous vaccines may be considered a complementary strategy, according to the herd’s epidemiological profile.
Laboratory diagnosis is fundamental for confirming the infection and adopting appropriate control measures. Traditional bacteriological methods, combined with molecular tests, allow for the precise identification of the agent and the differentiation of Streptococcus suis type 2, aiding in the understanding of the disease dynamics within the herd.
In addition to its importance in the swine industry, Streptococcus suis is recognized as a zoonosis, capable of infecting humans—particularly professionals who have direct contact with pigs or swine products. Thus, epidemiological surveillance, early diagnosis, and sanitary education are essential to protect animal health, public health, and the sustainability of the swine production chain.

In this context, Bioperfectus’ Streptococcus suis type 2 rapid test represents a practical screening tool to support sanitary surveillance in swine herds. The application of the rapid test enables the agile identification of suspect animals directly in the field, including asymptomatic carriers, assisting in the immediate adoption of measures such as segregation, management adjustments, reinforced biosecurity, and the referral of samples for laboratory confirmation. In this way, the rapid test complements conventional diagnostic methods, contributing to the early detection of more virulent strains, the reduction of the agent’s spread, and the strengthening of control strategies for Streptococcus suis type 2, providing benefits for both animal and public health.
