• Anaplasma phagocytophilum (formerly Ehrlichia phagocytophilum)[2] is a Gram-negative bacterium that is unusual in its tropism to neutrophils.
  • Anaplasma phagocytophilum causes the disease human granulocytic ehrlichiosis(HGE) and is most often spread through tick bites and is thus widely studied.
  • Anaplasmosis is a disease caused by the bacteria Anaplasma phagocytophilum primarily spread to people by the bite of an infected tick.
  • Anaplasma phagocytophilum is a gram negative bacteria that can cause disease in a wide variety of mammals including cattle, domestic and wild animals.
  • Summary Anaplasma phagocytophilum is an emerging pathogen known to cause human granulocytic anaplasmosis (HGA).

  • Anaplasma phagocytophilum is an intracellular, obligate bacterium that causes the disease known as human granulocytic anaplasmosis (HGA).
