Phagocytosis of coxiella burnetii by hyalomma dromedarii tick hemocytes






Acta Virologica 28(1): 48-52

Phagocytosis of coxiella burnetii by hyalomma dromedarii tick hemocytes

Hemocytes of laboratory bred half-engorged H. dromedarii ticks phagocytized intracoelomally inoculated C. burnetii organisms. Significantly higher phagocytosis of phage II than phase I C. burnetii was observed, irrespective of whether live, killed untreated or killed organisms treated with chloroform-methanol (CM) mixture were used. HCl- or KIO4-treated phase I cells were phagocytized to a similar extent as pahse II cells. More consistent results were obtained with hemocytes of male than of female ticks. Phagocytosis of phase I killed and live organisms was significantly increased by their preincubation with phase I but not with phase II immune rabbit sera.
