The direct blood smear detected infection in only 7 to 15% of cattle on 3 of the farms but in 75% on the 4th, which was at Panagarh where all the screened adolescent stock were ...

In India, 700 calves were immunized against Theileria annulata with a live attenuated schizont vaccine. There was no adverse reaction in the adolescent stock but 50% of the vaccinates ≤ 2-weeks-old died. At one centre (Parbhani) there was evidence that these young calves had already picked up a...

2 groups of 4 crossbred calves were inoculated with 16-tick equivalents of sporozoites or with 2 × 106 viable macroschizonts of T. annulata IVRI strain. 2 calves in each group had died by day 24 pi, and the survivors were challenged with a 32-tick equivalent of sporozoites on day 45 pi. Blood...
