Case of the Week 615

In the spirit of the American Thanksgiving holiday, I ' d like to present two related cases that were donated by two parasitologists in our wonderful parasitology community: George from Memorial Sloan Kettering and William Sears from the NIH. I ' m thankful for many things, and among them are this generous and supportive group that inspires and educates me each week. In his case, George noted the following in a stool concentrate:William was also kind enough to provide adults of this parasite, complete with more eggs (in utero and free). I ' ve seen similar adult worms in concentrated stool specimens.Can anyone put this whole picture together for us?
