A new integrated extraction and real-time PCR-based system for the detection of group B streptococci in antepartum screening samples enriched in Lim broth was compared to the CDC-recommended culture method. The BD Max GBS assay exhibited acceptable sensitivity (95%) and specificity (96.7%) compared to those of the culture method in this multisite evaluation.
Background Isolation of adipose tissue mesenchymal stem cells (MSCs) with current enzymatic methods has some limitations. For example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of MSCs. Also, it is accompanied with the increased risk of culture contaminations because of several handling steps.In this...
