Overview
Three strains of Ehrlichia (E. ewingii, E. chaffeensis, and E. Muris) are responsible for human infection. These resulting infections present themselves with very similar, if not the same, clinical manifestations. Endemic regions are different among the different diseases which may be used to diagnose the organism of infection.[1]
Classification
- Ehrlichiosis is a broadly used medical term for multiple bacterial infections.
- Three Ehrlichia species have been identified in Human infections:
- Ehrlichia Ewingii
- Ehrlichia Chaffeensis
- Ehrlichia Muris
- Infections with the above organism have similar or the same clinical presentation.
- Endemic Regions are different according to specific species.[1]
| Organism | Disease | Vector | Endemic Regions | Common Symptoms |
|---|---|---|---|---|
| Ehrlichia ewingii | Ehrlichiosis | Lonestar Tick | Southeastern and South Central United States | Fever, headache, chills, malaise, muscle pain, nausea, confusion, red eyes, and rash (60% of children and 30% of adults. |
| Ehrlichia chaffeensis | Ehrlichiosis | Lonestar Tick | Southeastern and South Central United States | Fever, headache, chills, malaise, muscle pain, nausea, confusion, red eyes, and rash (60% of children and 30% of adults. |
| Ehrlichia muris | Ehrlichiosis | Not yet established | Minnesota and Wisconsin | Fever, headache, chills, malaise, muscle pain, nausea, confusion, red eyes, and rash (60% of children and 30% of adults. |
- There are two types of Ehrlichia infections, human monocytotrophic ehrlichiosis (HME) and human granulocytotrophic anaplasmosis (HGA).
- HME is primarily transmitted by the Lone Star Tick (Amblyomma Americanum).
- HGA is caused by phagocytophilum.
- Clinical presentation is similar between HME and HGA, with symptoms such as fever, headache, and leukopenia.
