Abstract

Two calves each were injected with ground-up tick supernate (GUTS) prepared from 25 adult H. a. anatolicum infected with T. annulata and incubated for 0, 72, 96, 120 and 144 h (groups A to E respectively) at 37°C and 95% relative humidity. A further 2 calves (group F) were injected with GUTS...

Abstract

Three groups (A, B and C) of 6 calves infected with T. annulata were treated intravenously with menoctone at 12.5 mg/kg body weight in 4 divided doses on consecutive days when parasitaemia was >10%. Group B were also given oxytetracycline intramuscularly, single 20 mg/kg dose. Group C calves...

Abstract

In experiments involving 32 crossbred calves (Bos taurus×B. indicus) the effect of immunization by infecting the calves with Theileria annulata by s.c. injection of ground tick supernatant, and simultaneous treatment with buparvaquone given i.m. at 2.5 mg/kg body weight was studied. Groups of the...

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

20 crossbred calves aged 7 to 21 days were experimentally infected with Theileria annulata by means of an extract of Hyalomma anatolicum. The 6 controls died within 17 days. Seven calves were treated with a single i/m injection of buparvaquone at 2.5 mg/kg on the 11th day, when clinical...

Abstract

Five 2- to 3-month old cross-bred calves Bos taurus × Bos indicus were experimentally infected with T. annulata. The blood histamine level (BHL) was estimated twice before infection and then at 4-day intervals up to 24 days after infection (PI). The BHL rose significantly from 0.158 ± 0.006 µg/ml...

Abstract

Groups A and B (4 calves each) were injected with supernates of ground-up Hyalomma anatolicum, which had engorged on T. annulata-infected calves, irradiated at 6 and 7 krad, respectively (each calf received the equivalent of 25 ticks). Calves in groups C and D were given non-irradiated supernatant...

Abstract

The use of the capillary-tube-agglutination test in the serodiagnosis of Theileria annulata infection in cattle is described. The accuracy of the test was demonstrated by negative reactions with 87 sera from 'clean' calves and positive reactions with sera from recovered calves after experimental...

Abstract

Ten disease-free male calves aged 1-16 weeks were experimentally infected with T. annulata through infected ticks and blood samples taken on alternate days. Two calves were examined PM at 30 days, and the remainder were observed for 154 days. All calves had parasitaemia ranging from 0.1 to 15%....

Abstract

Calves were exposed to either 30 Hyalomma anatolicum anatolicum (from a calf carrying Theileria annulata) to produce acute theileriosis (15 to 98% of erythrocytes infected, severe symptoms and death within 3 weeks) or to 3 ticks to produce chronic theileriosis (0.1 to 10% parasitaemia, less severe...
