Streptococcus suis infection has been considered a major and worldwide problem in the swine industry, particularly during the past 15 years. The natural habitat of S suis is the upper respiratory tract (particularly the tonsils and nasal cavities) and the genital and alimentary tracts of pigs.<sup>2</sup> The most important clinical manifestation associated with S suis is meningitis. However, other pathological conditions have also been described, such as arthritis, endocarditis, pneumonia, and septicemia with sudden death.<sup>2</sup> Although S suis is considered primarily a swine pathogen, it has been increasingly isolated from a wide range of mammalian species, including human beings, and from birds, which suggests new concepts about some epidemiological aspects of the infection.

<!-- InstanceBeginEditable name="ArticleMain" --> Streptococcus suis is a gram-positive coccus, possessing cell wall antigenic determinants related to Lancefield group D, although it is genetically unrelated to other members of this group, such as enterococci. Streptococcus suis is a capsulated bacterium, with the composition of the capsule defining the serotype. There are presently 35 capsular types or serotypes. The original classification of S suis into Lancefield groups R, S, and T is erroneous, obsolete, and should be avoided. Strains of S suis originally defined as Lancefield groups R, S, and T correspond to capsular types 2, 1, and 15, respectively.<sup>1</sup> Also available as a PDF.
