Anaplasma phagocytophilum infection induces functional neutrophil
changes.
Using both Candida albicans and fluorescent-aggregate phagocytosis
assays,
we examined whether neutrophil and dimethyl sulfoxide-differentiated
HL-60
cell infection impairs internalization. A. phagocytophilum infection
significantly decreased phagocytosis compared to that of controls (P <
0.05). This further impairment of neutrophil function may promote
opportunistic infections and exacerbate disease.
