title: Development of Babesia ovata in the ovary and eggs of the tick, Haemaphysalis longicornis.
abstract: The ovary and eggs of adult tick Haemaphysalis longicornis (H. longicornis) infected with Babesia ovata (B. ovata), were examined at regular intervals of time. As a result kinetes could be detected in the ovary for the first time 6 days after engorgement. The kinetics could be classified into three types on the basis of their morphological characteristics. On the 2nd day after oviposition, round-formed protozoa were found in the ooplasm of the egg. In 5 days after oviposition, these round-formed bodies were transformed into club-forms. On the 9th day after oviposition, the kinetes were observed in the ooplasm. Morphologically, it seemed possible that B. ovata is transmitted by eggs of the tick, H. longicornis.
