Abstract

Heartwater was diagnosed in sheep at the Umm Banein Livestock Research Station, Blue Nile Province, Sudan.Cowdria ruminantium was isolated from sheep by subinoculation of blood into a goat. AdultAmblyomma lepidum ticks fed as nymphs on this goat transmitted heartwater to a Friesian (Bos taurus) calf. Brain stabilates from this calf, either snapfrozen into liquid nitrogen or frozen slowly in a deepfreezer at −70°C, with DMSD as cryoprotectant, were infective to cattle when inoculated subcutaneously.
