Anaplasma phagocytophilum
Active
Descriptions
A species of gram-negative bacteria in the genus Anaplasma, family Anaplasmataceae, formerly called Ehrlichia phagocytophila or Ehrlichia equi. This organism is tick-borne (Ixodes) and causes disease in horses and sheep. In humans, it causes human granulocytic ehrlichiosis. Source: National Library of Medicine, MeSH 2006
Human Granulocytic Ehrlichiosis (HGE) is an illness caused by a rickettsial bacteria transmitted by deer and dog ticks to humans. With HGE, also known as Human Granulocytic Anaplasmosis (HGA), neutrophils become infected by Anaplasma phagocytophilum and clusters of small bacteria may be seen within the neutrophils on blood smears during the terminal phases of the infection. Patients may exhibit fever, headache, malaise, myalgia, no skin rash, decreased WBC and platelet count and mild liver injury may also occur be present. Information from Emerg.

Anaplasma phagocytophilum is a rickettsial bacterium (formerly known as Ehrlichia phagocytophilum or Ehrlichia equi) that infects white blood cells and causes human granulocytic ehrlichiosis (HGE), also called human granulocytic anaplasmosis (HGA). A. phagocytophilum is a pathogen transmitted to humans by the bite of a tick (i.e., American dog tick, deer tick, and Lone Star tick), and may pose a risk of being transmitted by blood transfusion. The first symptoms of HGE/HGA normally begin one to two weeks after a tick bite, but a negative test for antibodies during the first seven to 10 days of illness is not always accurate. Both immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies usually rise near the end of the first week of illness. IgM antibodies are less specific than IgG antibodies and more likely to result in a false positive, so a concurrent IgG titer should also be run. Repeat testing several weeks after the original test, including comparison of antibody titers between the two time periods, is recommended. For IgG, the first sample typically shows a low or negative result, and the second typically shows a significant (four-fold) increase in IgG antibody levels.
