Answer

The mode of transmission is believed to be through direct fecal-oral spread and, possibly, through the eggs of E vermicularis (pinworm). Pigs have recently been identified as a natural host for D fragilis, [3] raising the possibility of transmission from porcine waste and the parasite has also been identified in untreated wastewater.
