Twenty susceptible calves aged 17 days to 7.5 months were infected with Theileria annulata by applying 25 infected Hyalomma anatolicum or by inoculation of ground-up tick supernate (equivalent to 25 infected ticks). All calves developed severe theileriosis and 19 died. Postmortem examination of the ...

Abstract

Each of 12 calves (6 to 84 days old) was inoculated with ground-up tick supernate prepared from 25 Hyalomma anatolicum anatolicum infected with Theileria annulata; a single intramuscular injection of oxytetracycline (20 mg/kg body weight) was given at the same time. Four similar calves were...

Abstract

The maturation of the Hissar strain of T. annulata in the salivary glands of Hyalomma anatolicum anatolicum was studied over 6-day periods in batches of ticks incubated at 36°C and equivalent batches fed on rabbits. Parasite maturation and sporozoite production were evaluated by 3 methods. By...

Abstract

Eighteen 7- to 21-day-old crossbred (Bos taurus × Bos indicus) calves were allocated to four groups (A to D). Groups A and B each consisted of six calves and groups C and D three calves each. Each calf in groups A, B and C was inoculated with ground-up tick supernate (GUTS) equivalent to two...

Abstract

Calves infected experimentally by s.c. injection of ground adult Hyalomma anatolicum anatolicum infected with Theileria annulata were treated with a single dose of buparvaquone (2.5 mg/kg body weight, given i.m. in solution) on day 7, 9 or 11 after infection. Body temperature had returned to normal ...

Abstract

20 cross-bred (Bos taurus × zebu) 7-to 21-day-old calves were inoculated with a ground-up tick supernate of Hyalomma anatolicum infected with the Hisar isolate of T. annulata. 6 calves acted as untreated controls and they all died of theileriosis within 17 days of infection. The remaining 14 calves ...

Abstract

Sixty-three 4- to 5-year-old crossbred calves were divided into 16 groups (A-P). Groups A and B were inoculated sc with ground-up tick supernate (GUTS) from T. annulata-infected or uninfected Hyalomma anatolicum anatolicum equivalent to 5 ticks/50 infected acini. Groups D and E received infected...

Abstract

Pooled immune serum from cattle with CF antibody titres of 1:160 to T. annulata was injected subcutaneously in three calves on days 4 and 8 of infestation with infected ticks. They developed severe theileriosis and two died. It is concluded that immunity to T. annulata is cell-mediated, not humoral.
