Understanding Anaplasmosis in Cats
Anaplasmosis is a tick-borne disease caused by the bacterium Anaplasma phagocytophilum. While infections with A. phagocytophilum are more commonly reported in dogs, natural infections in cats are rare (NCBI). Understanding the transmission and risk factors for anaplasmosis in cats is crucial for prevention and early detection.
Transmission of Anaplasmosis
Anaplasma phagocytophilum is primarily transmitted to cats through the bite of an infected tick, particularly ticks of the Ixodes spp. species. Transmission of the bacterium typically occurs within 24 to 48 hours of tick attachment. Cats with outdoor access are more likely to have contact with ticks, increasing their risk of A. phagocytophilum infection (NCBI). Ticks serve as the primary vector for transmitting the bacterium, and the Ixodes scapularis tick is particularly associated with transmission in the northeastern USA (MSPCA-Angell).
Risk Factors for Infection
The risk of anaplasmosis infection in cats is influenced by several factors. Cats with outdoor access have a higher risk of exposure to ticks and subsequent A. phagocytophilum infection. In contrast, cats living solely indoors are less likely to have contact with vectors like ticks, and their grooming behavior may remove ticks before pathogen transmission occurs. It is important to note that while cats may be infected with A. phagocytophilum, they may have lower levels of the bacterium in their blood compared to dogs (NCBI). This can potentially lead to false-negative polymerase chain reaction (PCR) test results, making diagnosis challenging.
By understanding the transmission dynamics and risk factors for anaplasmosis in cats, cat owners can take appropriate preventive measures to reduce the risk of tick bites and subsequent infection. It is essential to provide appropriate tick prevention methods and limit outdoor access for cats to minimize their exposure to ticks and the potential transmission of A. phagocytophilum. Early detection and timely treatment are crucial for the management of anaplasmosis in cats. If you suspect that your cat may have anaplasmosis, consult a veterinarian for proper diagnosis and treatment.

Symptoms and Diagnosis
When it comes to identifying and diagnosing anaplasmosis in cats, it’s important to be aware of the clinical signs and the diagnostic methods available.
Clinical Signs of Anaplasmosis
Cats infected with anaplasmosis caused by A. phagocytophilum may exhibit non-specific clinical signs. These can include lethargy, increased rectal temperature, anorexia, conjunctivitis, and dehydration. Other less common signs may include tachycardia, abdominal discomfort, ataxia, hepatosplenomegaly, and neurological signs. However, it’s important to note that not all cats carrying the Anaplasma bacteria will display symptoms.
The clinical signs of anaplasmosis in cats may manifest within a few days to a week after a tick bite. These signs can include poor appetite, lethargy, fever, stiff joints, limping, enlarged lymph nodes, bloody nose, dark bloody stool, bruising, wobbly gait, seizures, conjunctivitis, and protrusion of the third eyelid. If you suspect anaplasmosis in your cat, it’s important to consult a veterinarian for proper diagnosis and treatment.
Diagnostic Methods
To confirm a diagnosis of anaplasmosis in cats, veterinarians employ various diagnostic methods. These may include a combination of clinical examination, medical history assessment, blood tests, and tick identification.
Blood tests, such as polymerase chain reaction (PCR) testing, can detect the presence of Anaplasma bacteria in the cat’s blood. This test identifies the genetic material of the bacteria, providing a definitive diagnosis. Other blood tests, such as serology, can detect antibodies produced by the cat’s immune system in response to the infection. These tests may help determine if the cat has been exposed to Anaplasma bacteria in the past.
Tick identification is also important in diagnosing anaplasmosis. If a tick is found on the cat, it can be sent for testing to determine if it carries the Anaplasma bacteria.
In cases where a cat displays clinical signs consistent with anaplasmosis but diagnostic tests are inconclusive, a veterinarian may recommend a trial treatment with antibiotics to see if the cat’s condition improves. If there is a positive response to treatment, it can provide further evidence of anaplasmosis.
If you suspect your cat may have anaplasmosis, it’s crucial to consult a veterinarian for proper diagnosis and treatment. Early detection and appropriate management can lead to a successful recovery.

Doxycycline is the antibiotic of choice for treating anaplasmosis caused by A. phagocytophilum in cats. It is typically administered orally at a dosage of 10 mg/kg once a day for a duration of 28 days (NCBI). This antibiotic has shown efficacy in combating the infection and reducing the clinical signs associated with anaplasmosis.
After starting antibiotic treatment, cats infected with anaplasmosis often show rapid clinical improvement within the first 24-48 hours (Wagwalking). However, it is crucial to complete the full course of medication as prescribed by the veterinarian to prevent recurrence and ensure the complete eradication of the infection.
Monitoring and Follow-Up Care
During the treatment period, it is essential to closely monitor the cat’s response to the antibiotic therapy. Regular check-ups with the veterinarian can help assess the cat’s progress and ensure the effectiveness of the treatment. Monitoring may involve blood tests to evaluate the cat’s response to treatment and to check for any potential side effects.
In addition to monitoring, follow-up care is crucial to support the cat’s recovery. This may involve providing any necessary supportive care, such as addressing any additional health concerns or managing symptoms that may persist even after the infection has been treated.
It’s important to note that prevention is key in managing anaplasmosis in cats. Preventive measures, such as limiting outdoor access, using topical acaricides or tick repellents, and performing daily tick checks, can help reduce the risk of exposure to ticks and subsequent infections (MSPCA-Angell). By implementing these preventive strategies, cat owners can minimize the chances of their feline companions contracting anaplasmosis.
In conclusion, the treatment of anaplasmosis in cats primarily involves the use of doxycycline antibiotics administered orally. Monitoring the cat’s response to treatment and providing appropriate follow-up care are essential for a successful recovery. Additionally, taking preventive measures to reduce the risk of tick exposure is crucial in the management of anaplasmosis. With proper treatment, care, and prevention, cats affected by anaplasmosis can achieve a full recovery and return to a healthy and active life.

Comparing Anaplasmosis in Cats
When it comes to anaplasmosis, cats have distinct characteristics and differences compared to other animals. Additionally, diagnostic approaches play a crucial role in identifying and confirming the presence of anaplasmosis in cats.
Cats vs. Other Animals
Anaplasmosis, caused by the bacterium Anaplasma phagocytophilum, is primarily transmitted to animals through the bite of infected Ixodes ticks. While infections with A. phagocytophilum are commonly reported in dogs, natural infections in cats are rare. Cats with outdoor access are more likely to have contact with vectors like ticks, increasing their risk of A. phagocytophilum infection. On the other hand, cats living indoors are less likely to encounter ticks and their grooming behavior may remove ticks before pathogen transmission (NCBI).
The clinical signs of anaplasmosis in cats may include lethargy, anorexia, fever, conjunctivitis, elevated nictitating membranes, and less commonly, dehydration, tachycardia, abdominal discomfort, ataxia, and hepatosplenomegaly. The mean duration of clinical signs before presentation is approximately 2.8 days (MSPCA-Angell).
Diagnostic Approaches
Diagnosis of anaplasmosis in cats involves several methods to confirm the presence of the bacterium. One common approach is to identify morulae within the cytoplasm of neutrophils on peripheral blood smears. This technique allows for direct visualization of the bacteria within the cells. Another method is PCR analysis of peripheral blood, which detects the genetic material of the bacterium. Both these methods aid in the identification of anaplasmosis in cats.
Serologic tests can also be useful in confirming exposure to anaplasmosis in cats. However, it’s important to note that a 4-fold increase in convalescent titers after 14 days is needed to support a diagnosis of active infection. Serologic tests are particularly helpful in chronic cases to confirm exposure to the bacterium.
By understanding the unique factors associated with anaplasmosis in cats and the diagnostic approaches used to identify the infection, veterinarians and cat owners can effectively manage and treat the disease. Regular tick prevention measures and prompt diagnosis are essential in ensuring the well-being of cats and minimizing the impact of anaplasmosis.
