- Cat scratch disease is an infection caused by bacteria known as Bartonella henselae. Although about 40% of cats carry the bacteria in their saliva at some point in their lives, cats that carry Bartonella henselae do not themselves show any signs of illness.

- If you get scratched, bitten or licked by a cat, you could get what doctors call “Cat-Scratch Disease” (CSD) or “Cat-Scratch Fever.” While this doesn’t happen often, you should know all.

- Dec 28, 2017 Cat scratch fever (also known as catscratch fever or cat-scratch disease) is caused by a bacterium called Bartonella henselae. The Center for Disease Control states: About 40% of cats carry B. Henselae at some time in their lives, although most cats with this infection show NO signs of illness.

Bartonellosis in Cats
Bartonellosis is an infectious bacterial disease, caused by the gram-negative bacteria Bartonella henselae. It is also commonly known as cat scratch disease (CSD), or 'cat scratch fever.'
Cat Scratch Fever Symptoms
This is a zoonotic disease, meaning that it can be transmitted between animals and humans. In cats, the disease is generally transmitted through contact with flea feces. The bacterium is excreted through the flea and into its feces, which it leaves on the cat's skin. The cat, through grooming itself, ingests the bacteria, thereby becoming infected with the Bartonella strain. Humans do not acquire this infection from flea reservoirs. It is important to note that this bacterial infection can also be transmitted to humans and cats by ticks.
Although cats generally do not suffer from the infection, beyond possible fever, swollen glands, and some muscle aches, cat scratch fever can be passed to a human host when the infected cat scratches or bites a human. Saliva can also be a conduit for transmission, such as when an infected cat licks a skin abrasion or open wound on a human.
While infection of the Bartonella bacterium is usually mild in humans, the Centers for Disease Control and Prevention estimates that 12,000 people are diagnosed with cat scratch disease in the United States each year, and about 500 are hospitalized. Many of the infected are children, as children are most likely to play with kittens—which, in turn, are the most likely to scratch and bite as part of play.
Symptoms may become apparent within 7-14 days after the injury, but may take as long as eight weeks to present. Typical symptoms are swelling of the lymph nodes nearest to the bitten or scratched site, fever, headache, and a general malaise. Generally, the symptoms merit no more than a brief rest period until they resolve on their own, usually without medical treatment. Some patients require a course of antibiotics.
Fortunately, cat scratch fever is not fatal for humans, but it still poses great risks to immunocompromised patients, such as those with the AIDS virus, or those undergoing chemical treatment. While many cat owners do not need to concern themselves with whether their cats are carriers of this bacterium, those who must guard their health are advised to have their cats tested and treated, as well as to be especially vigilant against fleas.
Symptoms and Types
The majority of affected human patients are less than 21 years of age. In humans the following symptoms may be seen:
- Reddish small solid rounded bump or papule at the site of scratch or bite
- Swelling and appearance of infection at site
- Swelling of lymph nodes nearest the site of scratch or bite
- Mild fever
- Chills
- Fatigue
- General malaise
- Lack of appetite
- Muscle pain (myalgia)
- Nausea or abdominal cramps
Symptoms of cat scratch fever in cats include:
- History of flea and/or tick infestation
- No clinical symptoms are seen in most cases
- Fever, swollen glands
- In some cats, lethargy, lack of appetite, and reproductive difficulty may be seen
Causes
- Bartonella henselae bacterium infection
- Transmitted to humans through cat scratch or bite
- Transmitted to cats though fleas and ticks
Diagnosis
For affected humans, there is usually a history of being scratched or bitten, even lightly, by a cat. In many patients there is a characteristic small, reddish, rounded bump at the site of the scratch or bite. More specific testing may be required to isolate and identify the causative bacterium. As this disease does not cause any symptoms in cats, in most instances no diagnostic workup is required. In severe cases, your veterinarian will take blood samples from your cat for further testing. Complete blood profiles, biochemistry panels, and urinalysis often show no abnormalities.
Further testing will involve more specific tests for confirmation of cat scratch fever. Growing, or culturing, the causative organism from a blood sample remains the most reliable method for diagnosis. Polymerase chain reaction (PCR) is a more advanced test for detecting bacterial DNA, which may be done by taking a sample of tissue from the lesion. Even so, these tests do not always confirm bartonellosis as a cause for the disease, since the bacteria is not constantly circulating through the blood stream. Multiple tests may need to be conducted in order to ascertain the presence of Bartonella henselae.
Finally, an enzyme immunoassay (EIA) may be used to test your cat for an immune response to the Bartonella henselae bacterium, but the presence of antibodies does not necessarily mean that the cat is presently infected, only that is has carried the infection at some point in its life.
