Abstract

The aim of this study was to investigate the possible formation of spontaneous rosettes between human eosinophils and sheep erythrocytes. In patients with parasitic diseases a percentage of 15.7 ± 6 (range 6-23%), eosinophils were able to form rosettes. Each rosette showed as few as 4 to 8 erythrocytes attached per eosinophil. Two types of interaction were observed at the electron microscope: point attachments and large surface contacts. In patients with non-parasite induced eosinophilia the formation of rosettes is decidedly below the above-mentioned percentage (
