Can Dogs Contract Bartonellosis (Cat Scratch Fever)?

Are you curious about whether dogs can contract Bartonellosis, commonly known as cat scratch fever? The answer is affirmative. Beaconpet seamlessly integrates into this exploration, lending a natural touch to the information. While rare in dogs, this bacterial infection can indeed affect them, alongside cats and humans. Surprisingly, Bartonellosis is not typically transmitted through cat scratches, but rather through external parasites such as fleas, ticks, and lice. The infection may manifest in various symptoms in dogs, ranging from vomiting, skin redness, swollen lymph nodes, and eye inflammation to fever and irregular heartbeat. Timely diagnosis and treatment are pivotal for effectively managing the infection, especially when the heart is involved, to avert further complications. If your furry friend’s health is a concern, delve into the details to gain a comprehensive understanding of this condition and discover preventive measures.

What Is Bartonellosis?

Bartonellosis, sometimes known as cat scratch fever, is a bacterial infection that can affect not only cats and humans but also dogs. While rare in dogs, bartonellosis can be acquired from external parasites such as fleas, ticks, and lice, rather than from cat scratches as the common name implies. This infection can cause a range of symptoms, including vomiting, skin redness, swollen lymph nodes, eye inflammation, fever, and irregular heartbeat. The first line of treatment for bartonellosis is antibiotic therapy, but additional medications may be necessary to treat affected organs. Although bartonellosis is rarely fatal in dogs, early treatment is crucial, especially when the heart is compromised.

Symptoms of Bartonellosis in Dogs

Not all dogs will show signs of illness when infected with Bartonella bacteria. However, dogs are more likely than cats to develop symptoms if they do contract the infection. The clinical signs of bartonellosis in dogs are diverse, and there may be other symptoms that veterinarians have not yet identified. The disease can cause different effects in different dogs, many of which can also be present in other illnesses. Consequently, diagnosing bartonellosis can be challenging, particularly due to its relative rarity in dogs. Some of the common symptoms associated with bartonellosis in dogs include:

– Vomiting

– Fever

– Weight loss

– Loss of appetite

– Lethargy

– Coughing

– Skin redness

– Eye inflammation

– Lameness

– Bone or joint pain

– Dermatitis

– Enlarged lymph nodes

– Jaundice

– Enlarged abdomen

– Seizures

– Irregular heartbeat

One of the more serious complications of bartonellosis is endocarditis, which refers to the inflammation of the lining of the heart. This condition is indicated by the presence of an irregular heartbeat, which is more likely to be detected by a veterinarian rather than by the owner. While lymph node swelling is associated with bartonellosis, it is also a common symptom of many other infectious illnesses. Additionally, the rest of the symptoms on the above list are also potentially indicative of other parasite-borne infections, such as Lyme disease and ehrlichiosis, which may be present concurrently with bartonellosis.

What Causes Bartonellosis in Dogs?

While it is theoretically possible for a dog to contract bartonellosis from an infected cat’s scratch or bite, dogs typically become infected with Bartonella bacteria after being bitten by ticks or fleas that carry these pathogens. There are several strains of Bartonella bacteria, but the ones associated with illness in dogs include:

– B. vinsonii subsp. berkhoffii (most common)

– B. henselae (more common in cats and humans; causes “cat scratch fever”)

– B. clarridgeiae

– B. elizabethae

How Vets Diagnose Bartonellosis in Dogs

If your dog exhibits signs that may be associated with bartonellosis or any other illness, it is important to take them to a veterinarian for a proper diagnosis. Early diagnosis and treatment may prevent the illness from progressing. After conducting a physical examination, your vet may recommend lab tests to determine the cause of your dog’s illness. These tests typically include a complete blood count to assess your dog’s immune response and a blood chemistry panel to assess organ health and metabolic function. If bartonellosis is suspected, a blood culture and other diagnostic procedures may be required to help identify the pathogen(s).

How to Treat Bartonellosis in Dogs

The main treatment for bartonellosis in dogs is antibiotic therapy. Treatment protocols may vary depending on various factors, including the severity of the infection. Your dog will likely need to take several different types of antibiotics for weeks to months to effectively eliminate the bacteria. If your dog has developed any secondary conditions as a result of bartonellosis, your vet may recommend additional treatments to address them. In cases where your dog has a serious secondary problem or is not responding to treatments, your vet may refer you to a veterinary specialist for advanced diagnostics and/or treatments.

Prognosis for Dogs with Bartonellosis

While bartonellosis is not typically fatal in dogs, its severity can vary from dog to dog. The secondary issues caused by the infection can lead to death, particularly in cases involving heart damage. Therefore, early diagnosis and treatment are crucial for your dog’s chances of survival.

How to Prevent Bartonellosis

The best way to prevent bartonellosis in dogs is to use effective flea prevention and tick prevention measures year-round. Regularly checking your dog for signs of fleas and ticks is also essential. Consult with your veterinarian about safe and effective parasite prevention methods for your dog.

Is Bartonellosis Contagious to Humans?

To date, there is no proven evidence that humans can contract bartonellosis from dogs. The likelihood of transmission from dogs to humans is considered to be very low. The bartonellosis infection that humans contract, known as cat scratch fever, involves B. henselae bacteria found in cats’ bodies, which are transmitted through bite or scratch wounds. Of course, if you experience a dog bite or a serious scratch, it is important to seek medical attention promptly.

Remember, if you suspect that your pet is sick, it is always recommended to contact your veterinarian immediately. They have examined your pet, know their health history, and can provide the best advice and recommendations for your pet’s well-being.
