Question

what are the most commonly found bacteria in the placenta

Answer 1

The placenta gives some protection against infection for your baby while it's in the womb, protecting it against most bacteria. However, it doesn't protect your baby against viruses. Alcohol, nicotine and other drugs can also cross the placenta and can cause damage to your unborn baby.

Maternal infections caused by most organisms which can cross the placenta (including rubella, mumps, poliomyelitis, smallpox, rubeola, syphilis, malaria, toxoplasmosis, and infections caused by S typhosa, V fetus, L monocytogenes, cytomegalovirus, and herpes simplex virus) may result in abortion or stillbirth.
