ABSTRACT

The aim of the present study was to use staining with monoclonal antibodies to different cell surface molecules and flow cytometry to analyse the expression pattern of cell markers on camel blood eosinophils. Based on their light scatter charecterestics and green autofluorescence, camel eosinophilic granulocytes were identified as SSChigh/FSClow/Fl-1high cells within the granulocyte population. In comparision to neutrophilic granulocytes, camel eosinophils showed higher abundance of the cell surface molecules CD45, CD44, and CD11a but lower abundance of the cell markers CD172a and CD14. Collectively, the findings of the current study suggests a similar phenotype of camel, human, and bovine eosinophils.
