Abstract
(1) The transmission of heart water to two blesbuck is discussed.
(2) Infected A. hebraeum nymphae are capable of transmitting
heart water to the blesbuck.
(3) Heartwater could be demonstrated by blood sub inoculation
into susceptible sheep for a period of 35 clays in one blesbuck and for 9 days in another.
(4) The virulence of heart water virus did not change by passage.
(5) Infective nymphae do not loose their infection but retain
it to the adult stage.
(6) Clean larvae will pick up infection for transmission as
nymphae.
(7) Clean nymphae will pick up infection for transmission as
adults.
(8) The technique of tick breeding and feeding is briefly discussed.
(9) Both blesbuck died, one 13 and the other 7 weeks after tick
infestation.
(10) The significance of these experiments is discussed.
