I had hoped that this would have been a better video. The opening text/visuals are very confusing, and the cartoon human looks like a sad penguin. Is it supposed to be a human? Or human cells inside the human? Or a bacterium? And why is it looking so sad? #SadPenguin

The composition and stability of the vaginal microbiota of normal pregnant women is different from that of non-pregnant women – Roberto Romero – Microbiome – February 2014

  • Subjects: 32 non-pregnant women, 22 pregnant women who delivered on time
  • DNA extraction: Bead-beating, ZR Fecal DNA extraction kit (ZYMO Research)
