In canine ehrlichiosis, morulae are found in which type of cells?

In canine ehrlichiosis, the presence of morulae is specifically associated with monocytes. Ehrlichia canis, the primary pathogen responsible for this condition, infects these cells, leading to the formation of morulae, which are aggregates of the bacteria within the cytoplasm. This relationship highlights the role of monocytes as key targets for the organism, as they are involved in immune response and can serve as reservoirs for the bacteria.

Understanding this aspect is crucial as it also underscores the clinical significance of monitoring monocyte populations in dogs suspected of being infected with Ehrlichia canis. Identification of morulae within monocytes is an important diagnostic feature when evaluating blood smears from affected dogs. This understanding of pathophysiology not only informs diagnosis but also supports appropriate treatment strategies in managing canine ehrlichiosis.
