Anaplasma phagocytophilum

Test code:
B0101 - Ultrasensitive detection of Anaplasma phagocytophilum (formerly Ehrlichia phagocytophilum) by real time PCR


Anaplasma phagocytophilum is a gram-negative bacterium formerly known as Ehrlichia phagocytophilum. It causes anaplasmosis in horses, and also in sheep and cattle, where it is known as tick-borne fever and pasture fever respectively. The bacteria tend to attack neutrophils and when they infect humans, they can cause human granulocytic anaplasmosis.

The bacteria are transmitted to humans by the bite of an infected tick. The black-legged tick (Ixodes scapularis) is the vector of A. phagocytophilum in the northeastern and upper midwestern United States. The western black-legged tick (Ixodes pacificus) is the primary vector in Northern California.

When humans are infected, it may take one to two weeks before symptoms develop. Symptoms include fever, headache, muscle pain, skin rash (in rare occasions), leukopenia, thrombocytopenia and mild injury to the liver.

When animals are infected with these bacteria, they may develop lethargy, ataxia, inappetence, and weak or painful limbs, but the most severe changes are anemia and leukopenia. The infection is often confused with Lyme disease, another tick-borne illness.

Serological detection of these bacteria can take some time to reach a definitive diagnosis. Molecular detection by polymerase chain reaction (PCR) is a highly specific and sensitive way to detect the presence of these bacteria, and should be considered as an alternative to the serological method (Kirtz et al., 2005).


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of Anaplasma infection
  • Help ensure that herds are free of Anaplasma
  • Early prevention of spread of Anaplasma among animals
  • Minimize human exposure to Anaplasma
  • Safety monitoring of biological products that derive from susceptible animals.
