Theileria sergenti: transformation of zygotes into kinetes in vector ticks, Haemaphysalis (Kaiseriana) longicornis and H. (K.) mageshimaensis.
Invagination or transformation of a zygote of Theileria sergenti into a kinete was examined with Giemsa-stained smears of the midgut of vector ticks, Haemaphysalis longicornis and H. mageshimaensis. Zygotes invaginated almost simultaneously with the moulting of host ticks. They were round and oval, and measured 5.4 to 6.7 microns in diameter on average. The kinetes developing in the zygotes were situated in the periphery of cytoplasm and were spindle- or club-shaped.
