This is a very typical stool exam from the tropics. There are fertilized Ascaris eggs, Trichuris eggs and an unfertilized Ascaris egg in the bottom photo.

Ascaris, both fertilized and unfertilied; Trichuris trichuria. I found myself scanning the photos for something tricky hidden in the debris but didn't see anything else.

Trichuris trichuria and Ascariasis!

Mixed infections of trichuriasis and intestinal ascariasis. Trichuris ova seen, most probably T.trichiura based on the sizes. Also noted fertilized ascaris ova in 1st and 2nd pictures, and unfertilized ascaris ova in the third picture.

Well, everyone has the correct answer. This case is a nice pressure relief from the last case.

Ascaris and Trichuris. It is most likely that they are A.lumbricoides and T.trichiura, however a number of other species within the genera can infect humans, i.e. contact with pigs could resolve it as A.suum and T.suis co-infection.

Some of the eggs are interestingly asymmetrical which is quite unusual for T.trichiura but a characteristic I have seen a lot in T.muris. I am not suggesting that this is a T.muris infection, just a fun observation.
