NettetIf suspected colonies are confirmed as GBS, the broth can be discarded, thus shortening the time to obtain culture results. ... LIM broth may also benefit from the addition of sheep blood, although the improvement in yield is smaller and sufficient data are not yet available to support a recommendation. Nettet14. jan. 2024 · Briefly, the LIM broth enriched samples were sub-cultured onto blood agar plates and incubated for 18 to 24 h at 37 °C in 5% CO 2. The blood agar plates without any colonies observed at 24 h were re-incubated for an additional 24 h. If after 48 h no colonies formed, the culture was deemed negative.
