Here, the parasites multiply again and then remain dormant until the eggs hatch and the larval progeny infest a suitable host. After
attachment of infected seed ticks, sporozoites in tick salivary glands are injected into the mammalian host at the next blood meal
and the Babesia is activated and development recommences. The infective forms of B. bovis are injected into cattle by larval ticks;
those of B. bigemina are injected into cattle by nymphal and adult ticks. Sexual development occurs in the tick. B. bovis is
transmitted transtadially (one tick stage to another stage) but not transovarially.
