title: [Clinical significance of Streptococcus agalactiae isolation from urine samples of outpatients from health care centers].
abstract: BACKGROUND
  Streptococcus agalactiae is a well-recognized pathogen in the obstetric population and is a cause of invasive infection in adults with underlying diseases. Nevertheless, the role of S. agalactiae in urinary tract infections in the adult non-pregnant population treated in outpatient health care centers has been less extensively studied.
  
  
  METHODS
  The clinical significance of S. agalactiae isolation in urine samples from health care center patients was studied in five areas of Spain over a period of six months. The study protocol included the collection of personal, epidemiological and clinical data. A total of 85 patients were studied; 79 were women (17 pregnant) and 6 men.
  
  
  RESULTS
  Pyuria was found in 72.9% of the cases. A total of 26.4% (n = 18) of non-pregnant women and all the men had some type of chronic underlying disease and 35.3% (n = 24) had urinary disease. Among the pregnant women, 53% had asymptomatic bacteriuria and 35.3% had vaginal and/or urethral colonization. Among the group of men and non-pregnant women, the most frequent entity was non-complicated cystitis, seen in 66.1% (45 of 68) of cases, followed by complicated infection in 19.1% and asymptomatic bacteriuria in 11.8%. Of the 45 patients with non-complicated cystitis, 35 (77.7%) were over 40 years old and 19 (42.2%) were over 60 years old.
  
  
  CONCLUSIONS
  Among the population of non-pregnant adults treated in outpatient health care centers, S. agalactiae isolation from urine was found mainly in women over 40 years old and was the cause of non-complicated urinary tract infection in more than half of cases.
