1885 Encycl. Brit. XIX. 854/1 The epimerite serves to attach the parasite to its host... The phase in which it is present is called a ‘cephalont’, the phase after it has broken off a ‘sporont’.

1900 Jrnl. Royal Microsc. Soc. 337 The macrogametes are fertilised by microgametes, and in each case an oocyst is formed round the conjugates. The new nucleus (sporont-nucleus) divides, the daughter-nuclei also divide, and later the protoplasm, so that four sporoblasts are formed within the oocyst.

1912 E. A. Minchin Introd. Study Protozoa 166 Generations of individuals, ‘sporonts’, appear which do not multiply like the schizonts, but which as gametocytes, give rise to the gametes.

1924 R. W. Hegner & W. H. Taliaferro Human Protozool. 281 When the intracellular form breaks out into the digestive cavity (usually), body cavity or blood vessels, and when the extracellular forms become free from the epithelial cells to which they were attached, the parasites are known as sporonts. The sporonts are uninuclear but may be septate or polycystid.

1947 Ann. Rev. Microbiol. 1 7 Fusion of these gametes in pairs produces eight zygotes which become sporonts.

1977 Jrnl. Protozool. 24 55/1 Binucleate and quadrinucleate sporonts..were observed.

1970 W. Peters Chemotherapy & Drug Resistance in Malaria iv. 123 Pyrimethamine alone at a dose of 0·078 mg/kg had no sporontocidal action.

1977 Martindale's Extra Pharmacopoeia (ed. 27) 343/2 The biguanides..have..a rapid sporonticidal action against some strains.
