    The study evaluated the performance of an alternative culture medium, human blood agar with 5% washed red blood cells, for the development of Streptococcus agalactiae strains compared to 5% sheep blood agar. The sample consisted of 36 properly identified Streptococcus agalactiae strains. Results obtained from the ASHGL 5% medium showed 100% sensitivity and specificity after 24 hours of incubation. Positive and negative predictive values also reached 100%. The morphology of the colonies and the presence of beta-hemolysis on both sheep blood agar and ASHGL 5% agar were evident after 24 hours of incubation. Conclusion: The human blood agar with 5% washed red blood cells (ASHGL) is as effective as 5% sheep blood agar.
