Carrot Broth One Step™ for Group B Strep

carrot broth one step banner

Our new tile-less system allows for fast results for the cultivation and identification of beta-hemolytic strains of Group B Streptococcus.

No supplementation or additional steps required, eliminating the need to add tiles!

Strep B Carrot Broth™ One-Step is used to screen for Group B Streptococcus in pregnant women prior to delivery. Our one-step test is an improvement over conventional methods by increasing sensitivity, decreasing turn-around time, and lowering overall cost. All formulary components are now included in the broth, so the use of additional tiles is no longer necessary. Positives require no confirmatory testing!

Features and Benefits

  • Easy one-step process! Adding tiles is no longer necessary.
  • Easy read-out. Development of any orange to red color indicates a positive result.
  • For positives, there is no need for further subculturing to confirm.
  • Lower cost when compared to the LIM Broth method.
  • Carrot Broth™ was found to be more sensitive than LIM Broth and even PCR!
  • Can be used with liquid and gel-based transport systems.
  • Negative cultures from Strep B Carrot Broth™ should be subcultured to detect weakly or non-hemolytic strains of GBS.
  • Carrot Broth™ One Step is available in multiple formats that work on many automated inoculating machines.

Clinical testing of Carrot Broth™ One-Step demonstrated a sensitivity of 98.8% and a specificity of 98.2% for the recovery of Group B Streptococcus from patient specimens when compared to LIM Broth.

GBS Detect™ for Non-Hemolytic Strains

GBS Detect™ is recommended for the isolation and detection of weakly or non-hemolytic Group B Streptococci by inducing beta-hemolysis upon subculture from enrichment broth procedures such as Strep B Carrot Broth™ media or LIM Broth. GBS Detect™ contains special hemolysis-enhancing supplements that cause otherwise non-hemolytic strains of GBS to appear as beta-hemolytic, thus increasing the sensitivity of methods used to detect GBS colonization.
