Case of the Week 393
This week's amazing case was photographed by Emily F. in my lab. The specimen is a formalin-preserved stool specimen from our teaching archives - but not everything was dead! A great reminder for why we need to treat all specimens as potentially infectious - even when preserved in formalin for months.

Ascaris, beautiful!
Ascaris egg! Good chance this one was fertilized.

Long live the Ascaris. It really survived the preservation.

That is awesome and a little humbling... I saw this a couple of times after YEARS of preservation in Professor Cross' lab.
We see the same thing with Toxocara spp eggs in our lab, some of them have 4 or 5 years in formalin and the larvae inside still moves (were recovered from adult worms or from a sand pit from a public square).
