Anaplasmosis (Previously Known as Ehrlichiosis) in Dogs
Most dogs with Ehrlichia spp. and Anaplasma spp. appear to harbor subclinical infections so it is important to learn the potential symptoms.
Dogs with disease caused by infection with Ehrlichia spp. or Anaplasma spp. commonly present with fever, lethargy, depression, anorexia, and weight loss.
Lymphadenopathy is occasionally seen, and petechial to ecchymotic hemorrhages or epistaxis related to thrombocytopenia may be evident.
Occasionally dogs may present with neurologic disease, vomiting, or diarrhea. Ocular lesions including uveitis, chorioretinitis, and retinal detachment have been reported.
Dogs with E. ewingii and A. phagocytophilum have been reported to develop polyarthritis and may present with stiffness, swollen joints, or reluctance to move.
Coinfection with multiple Ehrlichia spp., Anaplasma spp., and additional tick-borne pathogens has been documented and when present, may complicate interpretation of the clinical presentation and diagnostic assays.
Disease caused by infection with Ehrlichia spp. and Anaplasma spp. is less well characterized in cats, but fever, lethargy, anorexia, weight loss, petechiae, joint pain, dyspnea, vomiting, and diarrhea have all been described.
NB-In my opinion, this (and all) tick-borne disease only fully manifests when natural immunity is compromised. As with the otherwise fatal epidemics of the past, e.g. Cholera, Plague, Spanish Flu, etc. homeopathic treatment can be extremely effective. Both in acute and chronic manifestations. I have had some great responses in patients that have already been treated repeatedly with doxycycline.–Dr. Jeff
