    Life Cycle:

    Life cycle direct without requiring intermediate hosts. The life cycle is in the range of 7 to 8 days.

    There are three probable modes of infection of the host: 1) direct ingestion of the eggs; 2) ingestion of food or water contaminated with the eggs; and, less likely,  3) retroinfection . Eggs depsoited in the environmane are believed to reamin viable for 4 wewks (Meade and Watson, 2014.
