StrepB carrot broth tiles with growth promoting factors........ variable

pH 7.4 ± 0.1 at 25°C

Source: This medium is available from Hardy Diagnostics.

Preparation: This medium is supplied as a prepared broth in tubes.

The StrepB carrot broth tile is added to a tube just prior to inoculation

with a vaginal swab. The tile must remain submerged in the broth.

Use: For detecting the presence of Group B Streptococcus infections

in pregnant women. This new screening test is an improvement over

conventional methods, by increasing sensitivity, decreasing turn

around time, while lowering overall cost. Tubes show an orange to red

color change, typical of group B streptococci. The production of

orange, red, or brick red pigment is a unique characteristic of hemolytic

Group B streptococci due to reaction with substrates such as starch,

proteose peptone, serum, and folate pathway inhibitors.
