Ehrlichiosis in Dogs Overview of Canine Ehrlichiosis. Ehrlichiosis is a tick-born disease of dogs characterized by fever, lethargy, lameness and/or bleeding tendencies. It is caused by one of several rickettsial organisms that belong to the genus, Ehrlichia. Ehrlichia canis (E. canis) is the primary causative agent in dogs. Rickettsia are small microscopic organisms that are different from both bacteria and viruses.

Dictionary Definition Rickettsia is a genus of non-motile, Gram-negative, non-sporeforming, highly pleomorphic bacteria that can present as cocci (0.1 μm in diameter), rods (1-4 μm long) or thread-like (10 μm long). Obligate intracellular parasites, the Rickettsia depend on entry, growth, and replication within the cytoplasm of eukaryotic host cells (typically endothelial cells).

typhus The specific type of Rickettsia that causes the disease also varies, as does the specific insect that can pass the bacteria along. Epidemic typhus, which is sometimes called jail fever or louse-borne typhus, is caused by Rickettsia prowazekii, which is carried by body lice. When the lice feed on a human, they may simultaneously defecate. When the person scratches the bite, the feces (which carrys the bacteria) are scratched into the wound.

Background Their genome is very small, composed of 1-1.5 million bases. Rickettsiae are a rather diverse collection of organisms with several differences; this prohibits their description as a single homogenous group. A general characteristic of rickettsiae is that mammals and arthropods are natural hosts. Rickettsioses are usually transmitted to humans by arthropods.
