APPROACHES TO IDENTIFY SURFACE PROTEINS OF ANAPLASMA PHAGOCYTOPHILUM DENSE-CORED ORGANISMS AS ADHESINS TO HUMAN P-SELECTIN GLYCOPROTEIN LIGAND-1
Anaplasma phagocytophilum is an obligatory intracellular bacterium that infects neutrophils to cause human granulocytic anaplasmosis. Sialyl Lewis x (sLex)-modified P-selectin glycoprotein ligand-1 (PSGL-1) is the confirmed receptor utilized by A. phagocytophilum to bind and invade human …

Anaplasma phagocytophilum remodels its host cell-derived vacuole into a protective niche by redecorating the vacuolar membrane with select Rab GTPases and bacterial proteins
Anaplasma phagocytophilum is an obligate intracellular bacterium that infects neutrophils to cause the emerging tick-transmitted disease, human granulocytic anaplasmosis (HGA). Following entry, the pathogen replicates within a host cell-derived vacuole that fails to mature along the endocytic …

THE ROLE OF OUTER MEMBRANE PROTEIN A IN ANAPLASMA MARGINALE CELLULAR INVASION AND ITS POTENTIAL AS A CROSS-PROTECTIVE ANTIGEN
Anaplasma phagocytophilum and A. marginale are the etiologic agents of human granulocytic anaplasmosis and bovine anaplasmosis, respectively. Both diseases can be severe, even fatal, and protective vaccines for each are lacking. We recently identified A. phagocytophilum outer membrane protein A …
