Anaplasmosis – Definition & Meaning

Anaplasmosis is a disease that affects both humans and animals, caused by the bacterium Anaplasma. The disease is transmitted through the bite of infected ticks and can cause serious health problems if left untreated. In this article, we will explore the definition and meaning of anaplasmosis.


Anaplasmosis is a bacterial infection that affects the red blood cells. The bacteria responsible for the disease is Anaplasma phagocytophilum, which is transmitted to humans and animals through the bite of infected ticks. The disease can cause fever, headache, muscle aches, and fatigue.


The term anaplasmosis comes from the Greek word “ana,” meaning “up” or “again,” and “plasma,” meaning “form.” The disease was first identified in cattle in the early 1900s, but it was not until the 1950s that it was recognized as a human disease.
