Figure 1From: Molecular evidence of Ureaplasma urealyticum and Ureaplasma parvum colonization in preterm infants during respiratory distress syndrome Agarose gel electrophoresis of urease gene PCR. 20 μL of amplified products for the urease gene were electrophoresed on 0.8% agarose gel in TAE buffer (40 mM tris-acetate, 1 mM EDTA, pH 8). A) Lanes 1–14: PCR results of TA samples of newborns with RDS; lanes 15–16: U. urealyticum and U. parvum PCR positive control; lanes 17 and 24: 100 bp ladder; lanes 18–23 PCR results of TA or NF samples of newborns without RDS. B: PCR negativity for Ureaplasma spp. of respiratory secretions from the control group; lane 13: 100 bp ladder; lanes 19–20: U. urealyticum and U. parvum PCR positive control.Back to article page
