title: [Group B streptococcal infections in adults, excluding genital infections].
abstract: Group B streptococcus (GBS) or Streptococcus agalactiae is recognized as a mayor cause of neonatal meningitis, sepsis and infections during pregnancy. However, in recent years there have been several reports concerning GBS infections in non pregnant adult population, specially in immunocompromised hosts and in patients with severe underlying diseases such as diabetes mellitus and cancer. We report a series of 45 cases which occurred in nonpregnant adult population during a period of two years. The average age was 50.8 years and most patients (38/44) had one or more risk factors: diabetes mellitus was the most significant underlying disease. The most frequent infection localization was skin and soft tissues followed by urinary tract infection. Several isolated cases of pneumonia, bacteremia, endocarditis, endometritis and peritonitis were observed. GBS infections should no longer be exclusively considered as perinatal and peripartum events. New clinical presentations are arising in non pregnant adult population with special incidence in immunocompromised hosts. We are obliged to keep this in mind and remember that SGB may be a possible etiologic agent for infections, particularly in skin and soft tissues of diabetic patients.
