Spontaneous bacterial peritonitis and bacteraemia caused by meningococci serogroup W clonal complex 11
In recent years, the incidence of invasive meningococcal disease (IMD) caused by serogroup W (SG-W) has been rising, in particular SG-W within clonal complex 11 (cc11), which has caused epidemics and is believed to cause severe and atypical IMD. This is a case report of spontaneous bacterial peritonitis and bacteraemia caused by meningococci SG-W cc11 in a 60-year-old female with systemic lupus erythematosus in prolonged remission as her only risk factor. Antibiotic therapy was initiated at admission, and peritoneal lavage was performed. The patient recovered successfully without sequelae.
