Chronic, subclinical, persistent infections have been documented for more than five-and-a-half months in dogs experimentally inoculated with a Swedish isolate of A. phagocytophilum and for almost one year in dogs inoculated with a human isolate from New York (NY18).6,7 However, no confirmed reports of clinical disease occurring in animals known to be chronic carriers exist. Retrieved from http://www.drlwilson.com/articles/antibiotics.htm, Anaplasmosis.

The antibiotic of choice is oral doxycycline. Membrane-bound vacuoles of intracytoplasmic organisms (morulae) can sometimes be observed in circulating neutrophils and, rarely, in eosinophils in acutely infected dogs. This includes the use of antibiotics, pain relievers, and anti-inflammatories. The optimal dose and length of therapy have not been firmly established, but an oral dosage of 5 to 10 mg/kg given twice a day for 30 days has been recommended.12,16 In most cases, clinical signs resolve rapidly. Because the deer tick and the western black-legged tick are also vectors for other disease, it is not uncommon for dogs to be co-infected with multiple tick-borne diseases such as ehrlichiosis, Rocky Mountain spotted fever, and Lyme disease. These assays are species-specific and can distinguish between these two infectious agents. We have used natural treatments quite successfully for tickborne illnesses. Incidents of chronically infected carriers later developing clinical disease have not been clearly documented. Greig B, Armstrong PJ. After starting medication, dogs often start to feel better in 1-2 days, but require treatment for at least two weeks. As in many aspects of life, an ounce of prevention is worth a pound of cure.. 18. The long term prognosis for dogs who have undergone a full course of treatment is excellent. 3rd ed. Clinical disease is often mild in naturally infected dogs, but some animals may have clinical evidence of bleeding (epistaxis or petechiation), particularly during the initial bacteremic phase when platelet counts may be reduced to < 20,000 cells/l. J Clin Microbiol 2000;38(11):4219-4221. Larger dogs need larger medication doses. The best ways to avoid anaplasmosis and other tick-borne diseases in dogs include: Year-round tick preventatives for all pets, Backyard management (e.g. Bakken JS, Dumler JS, Chen SM, et al. Because chronic infection has not been directly related to clinical disease and a therapeutic regimen effective in clearing the organism from an infected animal has not been established, treating clinically healthy, positive testing animals is of questionable benefit and not generally recommended. Doxycycline is the treatment of choice for anaplasmosis, and all other tickborne rickettsial diseases. If an animal no longer produces antibodies to the organism, this may indicate that the organism has been cleared from the body. Anaplasmosis causes one of two clinical syndromes: Fever, lethargy, polyarthritis, and, less often, gastrointestinal, respiratory, or neurologic signs, which are associated with A. phagocytophilum infection. Clinical signs. Anaplasmosis in dogs can be treated with a course of antibiotics, with most symptoms improving within 24- 48 hours after beginning treatment.

Rodents are thought to be the reservoir for A. phagocytophilum while dogs are theorized to be the reservoir for A. platys. What are some ways that I can prevent my dog from contracting anaplasmosis? A mild to moderate nonregenerative anemia is occasionally seen. Antimicrob Agents Chemother 2003;47(1):413-415. In some cases, an immune-mediated component may occur, making treatment with steroids and other supportive care necessary, depending on the patients clinical signs. Holistic treatment for the disease can help the dog fight anaplasmosis by itself. However, a positive test result in a clinically healthy dog should not be disregarded.

Grasp the tick close to the skin using tweezers or a device specifically designed for tick removal. The treatment for canine anaplasmosis is the same as that for other closely related tick-borne infections, including ehrlichiosis and Lyme diseasethe antibiotic doxycycline. Anaplasma platys was first reported in the United States in 1978 and has since been recognized to have a worldwide distribution, being reported in many European, Asian, and South American countries.18 This agent is uniqueit is the only intracellular infectious agent described in people or animals to specifically infect platelets (Figure 4). Retrieved from https://vcahospitals.com/know-your-pet/anaplasmosis-in-dogs. The natural mode of disease transmission has not been conclusively determined, but A. platys DNA has been amplified from Rhipicephalus and Dermacentor species ticks.19,20 Therefore, tick transmission is highly suspected. Rarely, neurological signs such as seizures have been reported. Nucleic acid amplification is the most sensitive method for detecting organism DNA in the peripheral blood of an infected animal. Some common antibiotics used to treat Anaplasmosis include, Doxycycline, Minocycline, Tetracycline, and Chloramphenicol. Dogs infected with anaplasmosis generally show joint pain and limping. Int J Sys Evol Microbiol 2001;51(Pt 6):21452165. The disease has been less frequently reported in Asia and South America.

Already have a myVCA account? In our experience, if an animal displays symptoms that can be associated with anaplasmosis, such as lameness or lethargy, these will often resolve themselves within 24 - 48 hours though they can last up to 7 days. An IFA test is also commercially available, and serologic testing has indicated that seropositivity in dogs can be high in the Southeast and Midwest.23 There appears to be some cross-reactivity between A. platys and the A. phagocytophilum with the SNAP 4Dx assay. Infectious diseases of the dog and cat. Many dogs we have worked with have responded wonderfully to our Antimicrobial formula. WebDoxycycline is recommended for dogs of all ages.

Limit the opportunities for your pet to bring ticks into your space by implementing tick control measures.

Symptoms of the disease vary depending on the organism affecting the pet, often making it difficult to diagnose. Early seronegative tests should not be considered a reason to stop therapy, because antibodies may take 1 week to develop in acute cases. The earlier in the course of disease the treatment begins, the better the outcome.

Anaplasmosis is a tickborne disease in dogs and cats that was formerly known as Ehrlichiosis and has two different forms. Reorganization of genera in the families Rickettsiaceae and Anaplasmataceae in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehrlichia and Ehrlichia with Neorickettsia, descriptions of six new species combinations and designation of Ehrlichia equi and 'HGE agent' as subjective synonyms of Ehrlichia phagocytophila.

Doxycycline at the dosage described above for A. phagocytophilum is apparently effective in treating A. platys infection.12 However, animals with circulating A. platys organisms that have moderate to severe clinical disease or that do not rapidly respond to doxycycline therapy should be tested for other tick-borne diseases. Clinical signs must be consistent with those found in animals with anaplasmosis and should rapidly resolve in most cases shortly after doxycycline therapy is initiated. Malcolm Weir, DVM, MSc, MPH; Ryan Llera, BSc, DVM; Ernest Ward, DVM. It is unknown whether a chronic carrier state can later result in chronic disease. Animals from endemic areas are often exposed to A. phagocytophilum, and 40% or more of dogs in these areas may be seropositive.9 However, since the morbidity is low, it appears that many animals may have antibodies to A. phagocytophilum without having any concurrent evidence of clinical disease.
