taken together with some observations on the tissue reaction ( phagocytosis of the often discharged rodlets by macrophages and also the more specifically acting heterophilic granulocytes ; isolation of the rodlet cells from the adjoining tissue as seen e.g . with the ruthenium red method ) , an exogenous parasitic nature of these cells seems more plausible , even if the evidence is not sufficient for an exact classification of either the cell or its characteristical inclusions .
