Leeuwenhoek wrote this letter to Henry Oldenburg about worms and (possibly) protozoa in animal bile; metals, skin, bladders, and taste.

Dobell, p. 220, offers the descriptions in this letter as the first of the "Sporozoa or upon any parasitic protozoon ... oocysts of the coccidian Eimeria stiedae."
