The maturation of Theileria annulata in Hyalomma anatolicum anatolicum stimulated by incubation or feeding to produce sporozoites.
Adult Hyalomma anatolicum anatolicum ticks infected with Theileria annulata (Hissar strain) were incubated at 36 degrees C or fed on rabbits. Tick salivary glands were stained whole with methyl green pyronin or ground up and deposited on microscope slides and stained with Giemsa's solution. Separate batches of ticks from both treatments were ground up, centrifuged and filtered to produce sporozoite suspensions. The suspensions were examined as deposits on microscope slides stained with Giemsa's solution. The Theileria in the salivary glands of the fed ticks matured more completely and rapidly than in the incubated ticks. The peak numbers of sporozoites from the fed ticks was greater by at least tenfold than the peak from the incubated ticks. This peak was on the third day of feeding or on the fourth day of incubation. It was confirmed that fed ticks will be more suitable for sporozoite production for infection of cattle and production of stabilates.
