Ehrlichia chaffeensis. E. chaffeensis causes human monocytic ehrlichiosis and is known to infect monocytes. [1] It has also been known to infect other cell types such as lymphocytes, atypical lymphocytes, myelocytes, and neutrophils, but monocytes appear to best harbor the infection. [1]
If ehrlichiosis is suspected, treatment should not be delayed while waiting for a definitive laboratory confirmation, as prompt doxycycline therapy has been associated with improved outcomes. [8] Doxycycline is the treatment of choice. [citation needed] Presentation during early pregnancy can complicate treatment. [9]
Ehrlichiosis is a tick-borne [3] bacterial infection, [4] caused by bacteria of the family Anaplasmataceae, genera Ehrlichia and Anaplasma. These obligate intracellular bacteria infect and kill white blood cells. The average reported annual incidence is on the order of 2.3 cases per million people. [5]
Amblyomma americanum ticks spread E. chaffeensis and E. ewingii bacterial infection in the Eastern and Southeastern United States, while A. phagocytophilum is spread by the Ixodes scapularis tick in the Upper Midwest; 1,518 cases of E. chaffeensis were recorded in southeastern, south-central and mid-Atlantic areas of the country in 2013 ...
Ehrlichiosis ewingii infection [1] is an infectious disease caused by an intracellular bacteria, Ehrlichia ewingii. [2] The infection is transmitted to humans by the tick, Amblyomma americanum . This tick can also transmit Ehrlichia chaffeensis , the bacteria that causes human monocytic ehrlichiosis (HME).
Anaplasma phagocytophilum (formerly Ehrlichia phagocytophilum) [2] is a Gram-negative bacterium that is unusual in its tropism to neutrophils. It causes anaplasmosis in sheep and cattle, also known as tick-borne fever and pasture fever , and also causes the zoonotic disease human granulocytic anaplasmosis .
From blood samples, 16S rRNA genes were amplified using standard polymerase chain reaction (PCR), and the genes were analyzed using gel electrophoresis and a GAP (Genetic Analysis Program) system. [4] This data was compared to all other Ehrlichia species, and Anderson et al. found that CGE is most closely related to E. chaffeensis and E. canis.
E. canis is a small, coccus bacterium with a single circular chromosome.Minute in size, E. canis is smaller than the other species in the genus Ehrlichia. [8] [10]The cell walls of this organism lack peptidoglycans and lipopolysaccharides typically present in at least small amounts in most other Gram-negative bacteria, which is believed to contribute to its ability to resist the immune ...
