The medical history of a previously perfectly healthy 45-year-old male patient with acute cervical pain is presented. From cultures of the discus C5-C6, Streptococcus agalactiae was isolated. The patient was treated with penicillin and clindamycin, and recovered quickly. Streptococcus agalactiae is reported as a cause of invasive infections in neonati and pregnant women, but in recent years, an increasing number of infections have been reported in adults. One of the reasons may be that, nowadays, there are more patients with immunocompromising diseases, such as diabetes mellitus and malignancies. Another factor may be an increasing virulence of Streptococcus agalactiae, caused by a myriad of virulence factors. Investigation of these factors may help to prevent a further increase of invasive infections with Streptococcus agalactiae by vaccination and antibiotherapy
