Investigations included placental tissue samples more than twice as likely have compared without placenta (P = 0.017, 95% confidence interval 1.1, 4.5). Of where made, 81% involved infectious abortion, with Campylobacter spp. (32%), Listeria (25%) Toxoplasma gondii (9%) being three most abortigenic pathogens implicated. remaining 19% a wide range non-infectious diseases.
