I don’t even want to know what’s in those bottles on the shelves behind him.
Seeing as how he is into the study of human parasites, they appear to be a collection of parasitic organisms. I think I can identify Guinea Worm and a TapeWorm.
Guinea Worm is a particularly nasty affliction... you drink infected water and the long, slimy white worms burst out of the skin on your leg and must be slowly extracted over days by winding them around a stick until they finally pop out.

Once a Guinea worm begins emerging, the first step is to do a controlled submersion of the affected area in a bucket of water. This causes the worm to discharge many of its larva, making it less infectious.
The water is then discarded on the ground far away from any water source. Submersion results in subjective relief of the burning sensation and makes subsequent extraction of the worm easier. To extract the worm, a person must wrap the live worm around a piece of gauze or a stick. The process can be long, taking anywhere from hours to months. Gently massaging the area around the blister can help loosen the worm up a bit.
This is nearly the same treatment that is noted in the famous ancient Egyptian medical text, the Ebers papyrus from 1550 BC. Some people have said that extracting a Guinea worm feels like the afflicted area is on fire. However, if the infection is identified before an ulcer forms, the worm can also be surgically removed by a trained doctor in a medical facility.
