PERSISTENT EHRLICHIA CHAFFEENSIS INFECTION IN WHITE-TAILED DEER [PDF]

Journal of Wildlife Diseases, 2001
Four white-tailed deer (Odocoileus virginianus) were inoculated intravenously with a deer-origin isolate (15B-WTD-GA) of Ehrlichia chaffeensis. The course of infection was monitored using indirect fluorescent antibody (IFA), polymerase chain reaction (PCR), and culture over a 9 m period. All deer became rickettsemic within 24 days post inoculation (DPI)

Reinfection withEhrlichia chaffeensisin a Liver Transplant Recipient [PDF]

Clinical Infectious Diseases, 2002
Human monocytic ehrlichiosis is an emerging infection caused by Ehrlichia chaffeensis, but reinfection with this agent has not been described. We report a case of reinfection with E. chaffeensis after a 2-year interval in a 56-year-old liver transplant recipient with frequent tick attachments.

Mitochondrial Dysfunction in Ehrlichia canis Infection

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transmitted by tick vectors, Ehrlichia canis (E. canis) is a Gram‐negative, obligate intracellular bacterium of zoonotic concern that infects both canine and human hosts. Its pathogenesis centers on the targeting of mononuclear phagocytes, where it establishes an intracellular niche by suppressing phagolysosomal fusion and evading immune detection ...
