For selective enrichment, aliquots were transferred to test tubes containing Tetrathionate (Oxoid) and Rappaport Vassiliadis (Oxoid) broths, and the respective tubes incubated at 37[degrees]C for 24h and at 42[degrees]C for 24h.
Selective enrichment broths for GBS are variations of Todd-Hewitt broth, with either 8 [micro]g/mL gentamicin and 15 [micro]l/mL nalidixic acid (TransVag broth) or 10 [micro]g/mL colistin and 15 [micro]l/mL nalidixic acid (Lim broth).
This finding might imply that: (1) intrauterine bacterial infections are present in certain patients; (2) low bacterial infection levels result in misdetection in samples directly smeared onto China blue and blood agar plates; and (3) certain bacteria require selective enrichment and suitable media for successful isolation.

Developed to give improved growth rates of Listeria over traditional selective enrichment media, LEE Broth enhances the expression of target antigens for most commercially available immunological test methods whilst maintaining suppression of non-target organisms.

By exploiting this difference, Li and colleagues showed that this approach could be used for the selective enrichment of fetal cell-free DNA fragments (to approximately 30%-50% of total DNA), thereby permitting the detection of otherwise masked fetal genetic loci, such as micro-satellite sequences, point mutations, or single-nucleotide polymorphisms
