Case of the Week 30

The two adult worms in this histologic section are within a mesenteric vein.
Identification (genus only)?

While only shown as a low-power, low resolution image, there are several features present that should allow you to identify the worms.

Well well that appears to be a beautiful example of Schistosoma spp with the male (larger) about to engage in lifelong copulation with the female.. bow-chica-bow-bow!!

I would put my head out and suggest that this is Schistosoma mansoni as the tegument is bumpy; the other intestinal Schisto species, Schistosoma japonicum, has a smooth tegument.
