Streptococci, and especially Streptococcus suis, are well-known pathogens in the swine industry. It is the most frequently reported diagnosis in the Online Monitor, and often the subject of conversation at the Veekijkertelefoon. Streptococci is considered in 22% of reports of health complaints in the Online Monitor. In 21% of sections, infection with streptococci is also considered the main diagnosis.

Streptococcus suis is most often shown to cause sepsis and meningitis, which is mainly seen back in weaned piglets. Weaned piglets are also the animal category where streptococci have the greatest impact.

Finally, several serotypes of Streptococcus suis are known. A recent inventory of strains that have been typed shows that Serotype 9 is found most frequently (41%), followed by almost a third of isolates not recognised as type 1, 2, 4, 7, 8 or 9. Serotyping can contribute to a correct diagnosis and, in combination with an antibiogram, help in appropriate treatment.
