Since the two organisms share the same tick vector, the diseases have a similar geographic distribution. All rights reserved. Dogs are by far the most common mammalian host, although rare reports of infections in cats, impalas, and sheep have been documented outside the United States.21,22. 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. The earlier in the course of disease the treatment begins, the better the outcome. In the United States, Ixodes scapularis is the primary vector in the upper Midwest and the Northeast, and Ixodes pacificus is the primary vector in the West. Early seronegative tests should not be considered a reason to stop therapy, because antibodies may take 1 week to develop in acute cases. though some pets may have minor or no symptoms at all. Reported signs include: A. platys infects the platelets and affect blood clotting. Anaplasmosis Treatment in Dogs A course of antibiotics such as minocycline, chloramphenicol, doxycycline, or tetracycline is typically used to treat Anaplasmosis in dogs. Laryngeal Paralysis In Dogs When To Euthanize? Animals infected with the most common form of anaplasmosis, A. phagocytophilum, will usally have symptoms for 1 to 7 days; however, some will have no or only minor symptoms. Collect these samples before initiating antimicrobial therapy because recent antibiotic administration, particularly tetracycline or its derivatives, increases the likelihood of a false negative result. It is important to remember that a dog diagnosed with one type of tick-borne disease may have other ones as well because of the shared vector. Treatment. More importantly, ticks carry a variety of diseases that can be passed to both dogs and humans. These are the same ticks that transmit Lyme disease, which increases the risk of coinfection with anaplasmosis. Some common antibiotics used to treat Anaplasmosis include, Doxycycline, Minocycline, Tetracycline, and Chloramphenicol. Many dogs we have worked with have responded wonderfully to our Antimicrobial formula. 15. As in many aspects of life, an ounce of prevention is worth a pound of cure.. WebDoxycycline is recommended for dogs of all ages. Once bitten, a tick must stay attached for 24-48 hours to transmit the bacteria. The first is avoiding exposure to ticks. However, dogs can increase your exposure to these ticks when they brush against vegetation where the ticks live and then unintentionally transport the ticks into your living environment. Canine anaplasmosis is often diagnosed by microscopic identification of morulae in circulating neutrophils in the peripheral blood (Figure 1) and sometimes the synovial fluid (Figure 2). Vet Pathol 2007;44:19. The most frequently observed clinical findings in dogs that would alert you to A. phagocytophilum infection are joint pain and lameness resulting from polyarthritis. Dogs infected with A. platys experience a cyclic thrombocytopenia. With this assay, many animals infected with A. platys will have positive test results for A. phagocytophilum. This form of anaplasmosis can be difficult to distinguish from Lyme disease, but new diagnostic capabilities are now available. They should be monitored and have their immune systems kept healthy using diet, supplements, and limiting exposure to unnecesary vaccinations, flea and tick pesticide products (ironically, but this is important - use natural methods instead) and other chemicals. Alleman AR, Wamsley HL, Abbott J, et al. Your veterinarian will begin by taking a full history of your dogs health and performing a physical examination. I recommend you add liver, eggs, oysters, spirulina, avocado and pomegranate juice to your dogs regular diet. You can consider giving your pup some immunity-boosting herbs like cats claw and echinacea along with oregano, thyme, and other herbs known for their antimicrobial properties. Many of our clients inform us that their dog is being treated for a tickborne illness after the fact. After starting medication, dogs often start to feel better in 1-2 days, but require treatment for at least two weeks. In some cases, an immune-mediated component may occur, making treatment with steroids and other supportive care necessary, depending on the patients clinical signs. Anaplasmosis can infect multiple mammal species but is not directly transmittable between animals, including, but not limited to dogs, cats, horses, cows, sheep, goats and humans. Anaplasma phagocytophilum morulae cannot be distinguished from those caused by E. ewingii, the causative agent of canine granulocytic ehrlichiosis.12 Clinical signs of E. ewingii infection are also identical to those seen with canine anaplasmosis, and these two infections cannot be distinguished by clinical (fever, lethargy, lameness, or reluctance to stand) or routine laboratory (complete blood count or synovial fluid analysis) methods. Anaplasma platys is transmitted by the brown dog tick. The best way to avoid tick-borne diseases such as Anaplasmosis is to use a veterinarian-recommended flea Most dogs with naturally occurring infection have mild clinical disease, although more severe clinical signs of fever, lethargy, pale mucous membranes, petechial hemorrhages, epistaxis, and lymphadenopathy can occur. Organisms may also be found in a small number ( 1%) of neutrophils in synovial fluid (Figure 2). The reason we mention this is because many animals are able to fight off tickborne illness on their own. In animals presenting with polyarthritis, synovial fluid analysis would reveal decreased viscosity and an increased leukocyte count (> 3,000 cells/l) with a predominant neutrophil population. However, direct transmission from animals to people or animal to animal is highly unlikely and has not been documented. 2. There are no natural treatment options that are clinically effective or recommended. Anaplasmosis in dogs is a lesser-known tick-borne disease that can affect the pet and the owner significantly. Ticks in the nymph and adult life stages are most frequently associated with transmission of anaplasmosis to dogs and cats, however this tickborne illness is much more common in dogs and so for the purpose of this article we will focus more on our canine companions. Limit the opportunities for your pet to bring ticks into your space by implementing tick control measures. Does My Pet Require Treatment for Anaplasmosis?

The antibiotic of choice is oral doxycycline. Though not always fatal, anaplasmosis should be diagnosed and treated on time to avoid any health risks. WebAnaplasmosis is commonly treated with the antibiotic doxycycline. Both A. phagocytophilum and A. platys are in the order Rickettsiales, which includes members of the genera Ehrlichia, Anaplasma, Cowdria, Wolbachia, and Neorickettsia. They are broad-spectrum and work against a range of bacteria including the good bacteria in the pets intestinal tract. Treatment for anaplasmosis concentrates on treating the symptoms of the disease and eliminating the bacteria from the body. Since PCR analysis can give false negative results, this assay is unreliable in detecting all subclinical, persistent carriers. Anaplasmosis is a bacterial disease that, in a dog, comes in two forms: Anaplasma occurs through many regions in the United States and Canada, correlating to the presence of the species of tick that transmit the disease. Prevention of Anaplasmosis in Dogs. WebTreatment of Anaplasmosis in Dogs. This does not make us happy; see side effects of Doxycycline above.

Dumler JS, Barbet AF, Bekker CP, et al. Anaplasmosis is often diagnosed with a blood test to detect antibodies. These tests are sent to a veterinary laboratory. Anaplasma platys infection can be diagnosed by light microscopic identification of morulae in circulating platelets. Most dogs are treated for 14-30 days, though improvement is often seen within the first few days of treatment. The areas with greatest incidence of canine anaplasmosis are the northeastern states, Gulf states, California, upper Midwest, southwestern states, and mid-Atlantic regions. How Is Anaplasmosis Treated? Anaplasmosis in dogs can be treated with a course of an antibiotic such as Doxycycline, Minocycline, Tetracycline, or Chloramphenicol. In light of these diagnostic challenges, once an animal with clinical anaplasmosis has been treated with the recommended course of doxycycline therapy and is clinically normal, administering a second course of doxycycline therapy or a different antimicrobial agent, in an attempt to obtain a seronegative status, is not recommended at this time. 8. An examination of the blood is the first step to evaluate the blood cells and platelets. Serological and molecular prevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, and Ehrlichia species in dogs from Minnesota. Infection with the more common form of anaplasmosis,A. phagocytophilum, often causes lameness, joint pain, fever, lethargy, and anorexia (lack of appetite). Though anaplasmosis is not a life-threatening condition, it can result in devastating long-term effects if left untreated for a long time. Experimentally, organisms appear in the peripheral blood between four and 14 days after inoculation and usually persist for up to eight days.5 Anaplasma phagocytophilum morulae may be seen in 1% to 27% of circulating neutrophils. Infection with A. platys results in a cyclic thrombocytopenia. Anaplasmosis is commonly treated with the antibiotic doxycycline. Grasp the tick close to the skin using tweezers or a device specifically designed for tick removal. Already have a myVCA account? European countries such as the United Kingdom, Norway, Sweden, Switzerland, and Germany also have reported infections in ruminants, dogs, and people. If an animal no longer produces antibodies to the organism, this may indicate that the organism has been cleared from the body. Doxycycline is the treatment of choice for anaplasmosis, and all other tickborne rickettsial diseases. Areas where Anaplasma phagocytophilum are more common include the northeastern, mid-Atlantic and north-central states, as well as California. An extended course of four weeks may be necessary for patients infected with Lyme disease at Many dogs we have worked with have responded wonderfully to our Antimicrobial formula.

When the blood test shows the antibodies for the disease, it indicates that the pets immune system is responding to the infection. A hallmark of this form of anaplasmosis is that it may result in subclinical disease or a chronic carrier state. Detection of granulocytic Ehrlichia species DNA by PCR in persistently infected dogs. The organisms are closely related and evidently share epitopes used in this ELISA. The vet may recommend completing the course of treatment even after symptoms improve. Minocycline, Holistic treatment for the disease can help the dog fight anaplasmosis by itself. There are several herb-based antimicrobial products available for pets that seem to work for anaplasmosis. Breitschwerdt EB, Hegarty BC, Hancock SI. You can consider including some beneficial herbs and supplements in its everyday diet to keep it protected against such infections. Int J Sys Evol Microbiol 2001;51(Pt 6):21452165. Infection with A. phagocytophilum, the species more commonly associated with anaplasmosis, causes lameness and is often confused with Lyme disease. Antibiotic susceptibilities of Anaplasma (Ehrlichia) phagocytophilum strains from various geographic areas in the United States. One of our concerns with the use of an antibiotic like Doxycycline is that this class of tetracycline antibiotics are known as broad spectrum, which means they are effective against a wide range of bacteria, including the beneficial bacteria that inhabit your dog and cats intestinal tract. I recommend you add liver, eggs, oysters, spirulina, avocado and pomegranate juice to your dogs regular diet. Signs due to thrombocytopenia are associated with A. platys infection.

The organism has a worldwide geographic distribution and is endemic in the upper Midwest, East, and Northeast regions of the United States as well as the western coastal regions. Since animals can have subclinical infections, it is important to recognize that clinically ill animals may have positive test results for A. phagocytophilum but be experiencing the clinical manifestations of an unrelated disease process. Antibiotic treatment is reserved for clinically ill dogs that have tested positive for the anaplasma bacterium. If there are no symptoms a complete blood count to check for abnormalities can be performed, if there are none then treatment should not be recommended with the animal monitored for anaplasmosis symptoms as always in the future. A wide variety of effective spot-on treatments, oral medications and tick collars are available to best fit your dogs needs; consult your veterinarian for the choice that is best for you.

The organisms disappear rapidly from the peripheral blood, and platelet counts rise quickly, reaching a normal value in three or four days. Treatment. Most animals will not need to be hospitalized. The vet may recommend completing the course of treatment even after symptoms improve. Maurin M, Bakken JS, Dumler JS. Clinical features and serology of 14 dogs affected by granulocytic ehrlichiosis in Sweden. 2023 MJH Life Sciences and dvm360 | Veterinary News, Veterinarian Insights, Medicine, Pet Care. 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. Pets who have a history of tick exposure, live in an endemic area, and have the appropriate signs are all considered at risk. As the two main anaplasmosis organisms infect different types of cells, the symptoms vary depending on which organism has infected the dog. Even so, alert owners of pets with known exposure to A. phagocytophilum to potential human exposure from infected ticks in the environment.
