From human feces. Untreated, phase microscoic image, 400X. Seems they are hatched larva in a packet. The left one probably is a packet of eggs. Unmoving. Suspecting some kind of parasite, probably new species. Two US labs failed to detect the would-be parasites.

If anyone know what is this, please email me at Blueskywilsonfaith@yahoo.com. Thanks.
