MAIN EDUCATIONAL POINTS from M184-1

1. Streptococcus agalactiae is a uropathogen responsible for urinary tract infection mainly in pregnant women, the elderly and those with significant underlying disease.
2. In non-pregnant adults, the Streptococcus agalactiae colony count definition for urinary tract infection is the same as the standard definition of a positive urine culture (≥10^8 colony-forming units [CFU]/L).
3. Streptococcus agalactiae bacteriuria should be reported from women in childbearing years regardless of the count.
