Abstract

Basophilic degeneration of the myocardium, which is considered to be a primarily human affection, was observed in two foetuses out from eleven aborted ones from a sheep-flock infected with Rift Valley fever. In sections stained with H&E the lesion appeared as a ba sophilic material subendocardially, in the ventricular septum, valves and appendages. This material stained positive with Meyer's mucicarmine and PAS stains, and menifested strong metachromasia with toluidine blue. The nature of the deposited material is discussed and is suggested to be a by-product of gyly cogen metabolism based upon the 8.8sociation of disturbance of glycogen metabolism in in fections with Rift Valley fever,
