The sequence of ultrastructural changes of bovine platelets during the fatal course of East Coast fever [caused by Theileria parva and transmitted by Rhipicephalus appendiculatus] was swelling; formation of vacuoles, pseudopodia and indentations; then thrombocytorrhexis and degranulation; and finally, thrombocytolysis. These changes led to thrombocytopenia and release of serotonin, resulting in petechiations and pulmonary edema.
