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

Killed C. parvum was used as an adjuvant for the production of non-specific resistance against T. annulata in cattle. Groups of cross-bred (Bos indicus X B. taurus) calves were administered C. parvum adjuvant subcutaneously and were then challenged with T. annulata-infected ticks 45, 60 or 90 days...

Abstract

Complement fixation tests for antibodies to T. annulata were positive at titres from 1:5 to 1:40 in 104 (53.6%) of 194 cattle on 3 dairy farms in Karnataka State, India. Antibody prevalence in pure exotic breeds, crossbreeds and indigenous cattle was 56.7%, 45.2% and 25%, respectively. Parasites...

Abstract

Calves receiving C. parvum alone, or with T. annulata antigen, were protected against lethal challenge 45 days later, whereas those with T. annulata alone died, inspite of the presence of complement-fixing antibodies. Those calves given C. parvum showed decreased neutrophil and increased monocyte...

Abstract

The preparation of a freeze-dried, inactivated vaccine from Hyalomma anatolicum ticks infected with Theileria annulata was described by D.K. Singh and others in 1979 (Tropical Animal Health and Production 11, 87-90). 200 mg of adjuvant from inactivated Corynebacterium parvum were added to each 2 ml ...

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...
